Andrew Walsh (andywalshart) added a comment to T85313: Using curves as bevel profiles causes unexpected issues with scale.

Update: if you start off with a bez curve (shift+A, Curve, Bezier) and use your shape as a bevel profile, this error does not occur. It's only when you create a circle privative (and either leave it as a circle or edit the shape of the circle) and bevel that.

sorry I deleted it. I'll try again next time it happens.

The project is missing other texture files, perhaps those are causing the issue. Could you please either pack all files used in the example project into the *.blend or create an archive that contains everything that is needed?

Any theories? I see other issues with dds textures here: https://developer.blender.org/T64758

Ok here we go. The dds file format seems to not be friendly in general. I can't open this kind of file in Photoshop. So likely Blender isn't happy either.

Update: I realised I had to delete the materials too, as that's where the problem lies. Now I can render again. Will see if I can drill down any more on the material. It's probably something to do with the image texture used.
edit: sorry, just saw your response. I'll see what I can do.

Andrew Walsh (andywalshart) added a comment to T84541: Eevee volume shader on imported VDB influences other volumetrics density (specified density attribute makes a difference).

Watch the attached video. Open the new Blender file and do what I do in the video. I've attached the vdb file. Essentially import the vdb cloud file, add the default volumetric shader and then scale it up and down and watch the density of the large cube's volumetric shader go in and out in proportion to the vdb file. It's a scaling issue of some kind related to some aspect of certain vdb files.

Andrew Walsh (andywalshart) added a comment to T84541: Eevee volume shader on imported VDB influences other volumetrics density (specified density attribute makes a difference).

I uploaded a video to show how it looks for me. Unfortunately the audio didn't capture but if you just re-read what I said above it's about as precise as it needs to be. In the video I open the file, note that there's nothing visible in the scene because the fog density of the shader (that's applied to a cube encompassing the scene) is set to 1.0. I unhide the vdb file and it erroneously causes the fog density to change, so now, once the vdb file is unhidden, we CAN see the scene. However, the density has not changed from 1.0. At the end of the video I re-load the file and it's still broken (the volumetric fog is neither 0 or 1, it's somewhere in between). You have to restart Blender to fix it. Using Eevee.

Try this. There's a cube in the scene with fog density set to 1.0 so you can't see anything. Look in the scene collections for the vdb file which is currently hidden. Unhide it and the fog will reduce in density visibly but will still be at 1.0

ok, thanks for all the info. Sorry if I'm unable to devote more time to it, I just get really busy. But I think in future I'll try to keep texture sizes as small as possible and see if that helps.

So I can confirm that the GPU is being used as per the check you mentioned in the Task manager. So that's cool.

Quick question while I look through debug logs. Is it fairly normal for the text file to be hundreds of megabytes?

Think this might be relevant too. Sorry. I'm crashing so many times I'm not sure if all these text files relate to the same crash. I think they do.

Not sure what the above means but it crashed again. Although I will say that I didn't start Blender with the blender_debug_gpu.cmd, I started it with blender_debug_log.cmd because I was expecting a non-gpu related crash. But just in case, here are the files (this is 2.90.1):

Just had another crash in 2.90 and wanted to run the logs past you just in case it was something different. I felt like this scene should have been a bit more stable for some reason. Crashed while activating cycles in viewport.

Do you think it's worth maybe saving incrementally and noting any new assets imported between increments? I have this happen all the time and if I had to guess, I'd say it was after importing a model.

usually this is resolved by restarting Blender. It's rendering again but the big issue is that it's just not using the GPU. I can select it and when it renders, the RAM is maxed out and GPU is around 0% and renders take 10 x as long.

oh, never mind, that was my confusion. I did test on 2.91 as instructed. I just thought that 2.91 was now released, so I tried on 2.90.1 this time. So yeah to confirm, I had also tested on 2.91 and it still crashed.

Confirmed that it also crashes in 2.91 alpha both in viewport and regular render window. Rendering fine in 2.83. Just to emphasize, my scene was rendering fine for a good while, it just suddenly stopped being able to. But I have had a few random and sudden crashes during rendering in 2.9x

Andrew Walsh (andywalshart) added a comment to T77882: Cycles VDB Artifacts (EEVEE WORKING).

Just to add some other examples of this bug. You can see the squares in the mist pass and then in another scene (circled in red) it's very subtle. Then I added some water (test002c) and you could faintly see the squares so I put some emission on the vdb just to really highlight the problem. Then I added a cube just to see if it was the water that was the issue (test002d) and what's odd is that I didn't touch the settings on the vdb material but it looks way different. The water is a cube with some volumetrics added. Let me know if you want the Blender file.

Andrew Walsh (andywalshart) added a comment to T78301: hitting undo once sends me back hours.

Update: I can confirm that closing Blender and re-opening it fixes the initial undo issue, but need to check that it doesn't come back as I've generally had weird issues with the undo function over the last few days.

Andrew Walsh (andywalshart) added a comment to T78301: hitting undo once sends me back hours.

Also worth noting with my current Blender setup is that I can't undo camera moves using CTRL+SHIFT+Z, nor does the global undo work for this. Just mention because it's undo-realted.
