Useful Resources


WE HAVE FLAIRS!

Please use the solved and unsolved flairs appropriately. If you mark your post as solved, please also post the solution if it is not already in the comments. Mods may add flairs when they have time. Please be considerate to the mods and the helpers and add your unsolved flair, and change it to solved when your question has been answered.


Rules:

1) Try by yourself first!

Try to find a solution by looking it up online – most issues can be resolved this way!

Doing your own research will save everyone time, and help you learn faster!

2) Be as detailed as possible

Describe your goals in detail. Explain what you've already tried and what went wrong. Add reference images if needed. Try adding a link to file so helpers can investigate issues you wouldn't know to. If you link a video, provide a time stamp.

Summarize your problem in the title, but add additional details-- text, images, links-- in the post body or in comments. Don't just write "Help!"

If images can help explain your problem, use clear, uncropped screenshots, not phone photos.

3) Let us know when you've solved it!

When you have figured out the solution, please mention it in the comments if it is not already there.

Also, apply the "Solved" flair so others know that the problem is resolved!

4) No artwork, tutorials, and feedback requests

Don't post finished art or tutorials. This includes vague requests like "What can I improve?" All posts must be focused on a specific problem you've encountered.

If you need to include someone else's art as a reference, add it as a link rather than an image in your top level post.

Feedback requests and tutorials should be posted to r/blender instead.

5) No bug reports

If you are sure you are doing everything correctly, but Blender is crashing, freezing, corrupting your files, etc – this is a bug. Make sure you are running the latest version - it might have the fix!

If the bug persists and you can reliably reproduce it, check out this guide for reporting bugs. By making a detailed report, you can help the Blender team identify and fix the bug! Posting your complaint on Reddit is unlikely to get help.

6) Be nice

Please be respectful that everyone has a different level of Blender experience, and all Blender users are welcome to post here.

If the community is helping you, try helping others too! The best way is to browse the "New" posts for unanswered questions and see if you can help.

Do not make mean comments or give unsolicited harsh criticism. Use the least inflammatory language you can to express your point.

No ALL CAPS titles. No question spam.


Other places to ask

Blender Stack Exchange

BlenderArtists

And don't forget the Blender manual itself.

If you ask multiple places, think about providing links to the various places the questions are asked. Seeing how others reason about the problem can be useful for helpers, and it will certainly be useful to those searching for the solution in the future.

How to add detail

To take an uncropped screen capture of your active Blender window in Windows, hit alt + print screen. You can paste this image directly into many image hosts like Imgur.

Reddit doesn't host arbitrary files (like a .blend) itself, and most users will not want to share their email address for attachments. You can host a file using a variety of file sharing services, such as Dropbox, Google Drive, Mega, or WeTransfer. Helpers will want the .blend file, not the .blend1 or .blend2 or any other automatic backups.

If your file is large, try enabling "compression" on the sidebar in the file save dialog. If helpers will need images, pack external data into the file. If they won't, unpack all external data to save space!

Consider making a simplified version of the problem for a linked file. This is an essential first step in troubleshooting most problems anyways, and will save your helpers time and bandwidth.

If you can't share the file because of commercial concerns, then consider recreating the problem in a different context, without any "trade secrets".

IK rig affecting other bones

So I have been trying to rig these leaves so that way they can split open, almost like tentacles. I have all of them parented to the bones with an IK rig set up so each leaf has an IK. I already checked weight painting, and all of it is affecting the appropriate model. However, when in pose mode, after transforming one IK, when I go to move another one, it glitches out a ton and somehow affects the other transformed bones. I don't know why it is doing that, and what I should do to stop it. I added a link to a GIF of whats going on below as well. Any help is appreciated, thank you!

Pixelated render on smoke simulation/animation

I'm trying to create a smoke simulation/animation I can use as vfx overlay onto live action film. I'm going for a colored smoke affect, like a smoke bomb in situations I can't film an actual smoke bomb.

I've created two spheres with liquid simulation to generate smoke, material nodes to thicken/color some, a smoke domain, and a turbulence object. The simulation seems to work, but the render is highly pixelated. I followed several tutorials and looked at some old help posts, and tried suggestions such as increasing resolution divisions on smoke domain as well as being sure to apply scale to all objets. Even at 512 resolution divisions, the smoke is pixilated.

I'm rendering with Cycles - 64 max samples, denoise on.

Blender 4.0 Sequencer option in render-no video or no audio

When I rendered my animation the first time it was all black, but had sound. Did some googling, clicked the "sequencer" option and it fixed the video, but then it rendered without my audio. My professor is MIA and my assignment is due in a few days. Please help?

Textures showing up as black/Heavily Darkened

I've been trying to get these textures to work for a while and they seem to always default to a glossy black or a veryt dark version of the actual textures. The model and textures are from dark souls 3 and I fixewd the uv maps so the corresponded to the correct portion of the texture map but it still shows up darkened or just black. I was able to get the transparency setup on the hair and it only looks black in viewport so that is fine but everything else is not working properly.

It could be my node setup but im not to great at the shader part so I could have screwed up there any help would be great and I can send the .blend if needed

Thanks

Unable to edit Premade Animation from a model I downloaded from SketchFab

I downloaded the Solus the Knight model from SketchFab for a personal project Im working on. When trying to edit any of the prebuilt animations Im only able to alter the variables around the animation (location, scale, rotation etc...) and not the animation itself. My goal was to make this animation slower and travel a bit further. Can anyone give me a solution to this issues?

Here is a video to help you visualize the problem: https://youtu.be/xXC8j84bA7Y

Textures didn't apply on Blender

Firstly, I'm a beginner on Blender and like to make objects photogrammetry, which I take a 360 angle photo around a specific object by camera and then put those photos on Meshroom to export the object by its texture. Furthermore, I import the OBJ file on Blender and soo on. I use it around 2 months but I face some issues with applying the texture on Blender.

My last object goes well which all textures were applied.

That was the texture file which Meshroom exported.

So then, I started to make another photogrammetry object and here the problem begins. When Meshroom finished and the texture file get exported, I noticed that their is extra EXR file for the texture in the main texture file.

The \"texture_1002.exr\" file is the extra file.

The problem is when this extra EXR file get exported and then I import the OBJ file on Blender, their isn't texture applied as every time this file exists the texture on Blender get disappeared.

That is my object which is zero texture applied.

I want a solution from the experts on Blender or anyone who faced this problem before and solve it, for that problem please as possible.

Ceramic floor tiling tips?

Hello guys! I was wondering if anyone would know something about more exact approach to floor tiling from single image downloaded from manufacturer site in correct real life dimensions? So far, I know that i can use Materialize to get all of the texturing maps for a material from single image, but is there some kind of a way in Blender that would make me able to randomize tiles so that I avoid repetition? Or should I do that part of the proces in Photoshop/Illustrator? And how can I set the repeating image of a tile to correct size like 60x60 cm, 120x60 cm and so on..? Havent managed to find any kind of tutorial that would cover all of these questions in once, so there it is..

Campfire Silhouette Halo Effect

How to approach creating albedo textures for low poly buildings.

Hi. I would appreciate your advice how would you create textures for mobile game asset.
I mean particualty in the same style as in the blog post by Martin Teichmann
https://www.artstation.com/blogs/mayday/Lae3/miniature-city-unreal-5
Textures consist only of albedo without any fancy PBR channels, but it's a little bit hard for me to grasp how to begin learning this technique. Ian Hubert texture style could work, but it could be helpful to receive suggestions from other people. His tutorials are called lazy for a reason. Thanks.

Help with fluid simulation

Processing img zfzqnbgzqexc1...

Hi blender community, I'm trying to create a fluid animation with bubbles. Unfortunately when adding bubbles function and linking it in a sphere Blender becomes very very laggy, literally can't do anything RAM and GPU goes almost 100%.

I'm working on a MacBook Pro M2 32GB Ram and never had and worried about these kind of issues.

Is this the wrong machine for this kind of fluid simulations? Thank you for helping.

How can I cut a shape without the procedural texture going crazy?

Kind of new to Blender (at least in the procedural material part of blender).

I'm trying to do a TPLO surgery animation, and I need to "cut the bone" on the head, but I'm using a procedural texture and it's just making a mess because of the boolean.

https://preview.redd.it/u8btoznbnfxc1.png?width=1919&format=png&auto=webp&s=ae9ff62b71d7e42c91d102feb2741505a63eaac8

I know the boolean is destructive, so my question is: is there any other way to do it? Does it have to be manually made or is there a way to do it?

I already tried:

  • Split Edge modifier
  • Manually fixing the topology
  • Marking as sharp/seam
  • Using UVs

Is there no way to do this?

This is the procedural material I'm using, just in case a picture of it is needed:

https://preview.redd.it/i3vus50cpfxc1.png?width=1446&format=png&auto=webp&s=f30960dffc6eaa53c4bebe4593cebe21c6cc7e64

I 'm almost sure that the specific culprit is probably the "pointiness" geometry connected to the color ramp, but I'm not sure how to fix that without having to change the texture, not sure if there is a method to "ignore" certain parts of the mesh.

I also tried assingning specifically that border another material, but it obviously doesn't work as I want it to. Could anybody point me in the right direction? Thank you in advance

Reflection of a lens for a particular object?

https://preview.redd.it/g7r4x689qfxc1.png?width=1293&format=png&auto=webp&s=63cb2077c76d2f15e59e72d89e45ac38c0d6ace6

Hi, this is a frame of a gif for a scientific presentation. As you can see, you are able to see the refraction of the black planes through the lens. I don't want this feature because it is not realistic, but I don't want to change the features of the lens because it looks realistic and I need this type of refraction for other objects.

Is there any way that I can tell it that I don't want to see the refraction fro the two black/white planes? Thank you

Modeling | Circle Topology

Hi,

as seen in the screenshot, I have two models. The mesh on the left (new) is the one I have a problem with. The mesh on the right is the old one which I made but I'm redoing it since it has really bad topology.

On the right mesh you can see the circle in the middle which is cut in half. The same I want to do on the left mesh, but this time in the correct way. I tried many approaches, but I'm always ending up messing up the mesh. The right mesh looks ok in renders, but modifying it, for example using the decimate modifier, does not work because of the bad topology.

What is the best way to archieve the same results as on the right mesh but with a good topology?

Thank you for any hints. If this questions is somehow a duplicate or is missing any details, please let me know.

Help cutting shape out of object please

Hey,

Sorry if this is a stupid question, I'm a complete noob to blender and just trying to help someone out

I'm trying to make a teardrop shape with this shape cut out of it.

I've created the teardrop shape with a cube, scaled the top points to 0 and then adding a subdivision modifier. To get the larger circle I've then added a circle and used the knife project tool to try and cut out the shape but when I do this it doesn't remove a full circle (it goes like this).

I've tried this with both a cube and a plane but I'm having the same issue.

I've figured out that it's something to do with the subdivision but I'm not sure where to go from here.

If anyone could suggest any better ways to either make the teardrop shape or to cut out the shape that would be appreciated.

thank you

Can't parent mesh to armature with empty groups/automatic weight

I have my mesh and my armature, and I want to parent them together so when I move an arm of my armature, the mesh moves as well.

Right click -> Parent -> Armature Deform With Empty Groups/Automatic Weights Hasn't done anything very useful for me... When I move the entire armature, the mesh moves as well, but body movements like arm or legs rotation in the armature don't do anything in the mesh. (see images below)

Textures Will Not Stop Flickering after Animation

Hello,

I'm in the rendering stage for my newest project and I've noticed that after I render there are alot of textures that seem to flicker continuously throughout the animation. I've tried the following based on my google searches but nothing seems to work.

-Flipped normals of object for all those are were facing the wrong way.

-Selecting the objects individually and clicking "merge by distance" to get rid of any double faces. When I did this the popup message at the bottom stated "removed 0 veriticies.

-Checked to make sure objects were set on auto smooth. Example

I provided a short example of the some objects flickering. In the video, if you look at the room to the left or the floor to the right, or the right plane I put in for this test, you can see that the texture seems to shimmer/flicker. I have a feeling this might relate to the lighting but I'm not sure as nothing I found on google/youtube seemed to point to this being the issue.

Also maybe important to mention, alot of the textures I use come from the add-on "Sanctus Library". I'm not sure if that has anything to do with it or not.

Should I upgrade RAM or it's something else?

About every fourth render Blender crashes due to exceeding the limit of available memory, including page files

Previously, it was enough to simply optimize the project, tweak the subdivision, remove some objects, in general, reduce the amount of geometry in the frame. However, recently such methods stopped working because projects are becoming heavier and more details are being added. Sometimes an entire system freezes for several minutes; from my experience and observation, the problem I described occurs.

Rendering is done exclusively on a video card (rtx 2060 super 8 gb) which is enough for me

The Ryzen 5 2600x processor is definitely a little old, but it gets the job done

The system is on an SSD, the blender and projects are stored on another drive, also an SSD

How does using limited dissolve affect the overall model?

Hi everyone,

sorry if this is the wrong format I dont post often, I had a university assignment recently and used blender to make my models but i had to keep my poly count low so i resorted to using limited dissolve whenever i could to remove extra vertices and have less triangles. Visually i dont see a difference (except in edit mode which didnt really matter) but i want to know if it affects the model negatively or if its bad practice or anything

How to change origin point?

I'm a beginner trying to do Proportional Editing on an object and I want to smooth some vertices. Every time I enable the circle on Proportional Editing it stays at the origin point in the middle of the scene, but I want the point to change depending on what I've selected, if that makes sense.

For example, in this video the VTubers were able to select Scale and have the origin point change to be in the center of the object. Whereas when I try to do the same, my origin point remains where it was when I first opened the program. I can't find an explanation for this in the video so does anyone here know how to fix this?
