Robert Rioux (riouxr) added a comment to T73076: Optix render kernels constantly reloading on Linux.

In my case, it rebuilds every time I change a settings in the shader. I added a brightness contrast node. If I change any of the two parameters, it reloads. It's unusable.

Robert Rioux (riouxr) added a comment to T80032: Shrink mask doesn't work if all polys are masked on non-watertight geometry.

There is boundary automasking which already pins mesh borders.

Robert Rioux (riouxr) added a comment to T80032: Shrink mask doesn't work if all polys are masked on non-watertight geometry.

In Maya, there's a cool feature for sculpting that I dearly miss. If you have vertices selected before going into the sculpt tool, then only the selected vertices will be affected by the sculpt tool, so no need to deal with masks (masks are also available). There are many ways to select vertices in Blender and that would be super useful. It's much faster than having to create masks. This is the point of view of a hard surface modeler. It seem like the sculpt tool was design with organic modelling in mind, X mirror being on by default (which is very annoying for hard surfaces). X mirror should not be turned on by default or at least it should be in the prefs somewhere to that the user can decide. OK, I'm done.

Robert Rioux (riouxr) added a comment to T80032: Shrink mask doesn't work if all polys are masked on non-watertight geometry.

I tested it again and I realized that as soon as the mask reaches the edge of the geometry, it won't shrink again, so it's not only when everything is masked.

Robert Rioux (riouxr) added a comment to T80032: Shrink mask doesn't work if all polys are masked on non-watertight geometry.

I wrote non-watertight because if you grow the mask all the way on a sphere, then it won't have a way to know from where to shrink, unless Blender keeps the history in memory. Anyway, as a user, I don't really care how the code works. If the function is called shrink mask and in that situation it doesn't do it, then it's a bug. :-) Cheers

Yeah, I see what you mean. So if you make keyframes but don't modify the handles at least once, the function doesn't work properly but if you do make a change, then it's ok. Well, now I have a workaround. Thanks Richard for taking the time to figure it out. Your help is appreciated. Cheer.

Robert Rioux (riouxr) added a comment to T79804: Changing extrapolation in graph editor modifies the tangents. .

No offense but when a tool doesn’t do what it’s supposed to do, that’s a bug. Here, it’s supposed to extrapolate the curves. That means keeping the tangents the way the are and extend them to infinity. This is not what’s going on. It screws up the animation curves and gives you a totally wrong result. Again, the tangents should not be modified at all when calling the function. The documentation is wrong as the example doesn't show what happens in the case I showed in my example. I gave you a picture to show you that it's broken. I would ask you to please reconsider.

I tried all the way back to 2.80. Looks like it never worked on my system. Or the nVidia driver was updated and it broke it. Hard to tell. I actually have two graphic cards, a 780 ti and a 980.

Robert Rioux (riouxr) added a comment to T77154: Alembic doesn't correctly interpolate between matrices with negative scale..

I juste checked in Maya. At 30 fps, the animation runs from 1001 to 1075. If I switch Maya to 24, it goes from 1251 to 1344, so 93 frames. The animation is interpolated to match the new frame rate. This is just a single object but imagine if you get a vehicle with wheels and doors and all and half of them have negative values. that would be a major issue. There must be a way to fix that. Alembic is designed to move animated objects from one software to another. That's the main reason we use it, so you have to find a way to make it work. In our company we keep exchanging assets from Maya, Nuke, Houdini and Blender. Alembic is the only method that works on all platforms.

Well, no offense, but it must be mathematically possible if Maya and Nuke can handle them properly. Sometimes you get alembic file from client and you can't always ask them to regenerate them. Cheers :-)

The problem is not with the frame range. If you play the animation at 30 and 24 fps, you will see that the animation itself is not the same. It's fine and smooth at 30 but at 24 the geometry flips back and forth. Just put a texture on it and you will see.

On the same file I sent you, sometime when I reopen the file, the explosion to the right will render in the viewport but not in the render view. The one on the right uses the principal volume and the one on the left is one I did myself. The one I did renders way faster but I can't get all the details and color variation that the principal volume shader does,. That's not a bug, it's me complementing you on your shader :-)

Robert Rioux (riouxr) added a comment to T72734: UDIMs don't behave properly on imported geometry.

I actually don't understand why you need to make a tile list. I don't know of any 3D package the requires the user to create UDIMs. If you move the geometry outside 1,1, then it's on another UDIM and that's it. You just need to make sure that there's no overlap from one tile to another (a checking tool for that is a must). You can see on this image some geo where the UVs are on different UDIMs. But I didn't create them. I just moved the UVs where I wanted them.

In this case, you would not turn on the tile option. This is just regular UV mapping.

Robert Rioux (riouxr) added a comment to T72734: UDIMs don't behave properly on imported geometry.

You (the user) don't want to rescan for textures. When you call the rendering engine, the engine will find the textures as it knows it's looking for UDIM textures (by choosing the tile option).

Robert Rioux (riouxr) added a comment to T72734: UDIMs don't behave properly on imported geometry.

Actually, the way it works is the following. You open or import a file with UV spread on different UDIMs. Textures are irrelevant at this point as the UVs are part of the geometry. When you assign a textures (I use Maya as an example), when you select one of first tree options as mentioned in my previous message, the texture name will change from foo.0001.jpg (or foo.u1v1.jpg) to foo.<UDIM>.jpg. Then Maya will seek textures according to the UVs. If it finds a texture in UDIM 4,5 (or 4005), it will assign the corresponding texture to the geometry. UDIMs are not created according to textures, unless you manually create them.

Robert Rioux (riouxr) added a comment to T72734: UDIMs don't behave properly on imported geometry.

Maybe this can help. Different software use different ways of dealing with UDIM names. Maybe it would be important to support all 3 systems as you never know where stuff may come from. This is from Maya.

Robert Rioux (riouxr) added a comment to T72734: UDIMs don't behave properly on imported geometry.

You have to support tiles being in any order possible (but never go beyond 10 on a row, that's the standard). If you get a model, let say, from Turbosquid that has UDIMs, they may not be in the perfect order. Or if you delete part of your geometry and it creates gaps in the UDIMs, it needs to be supported. So generating the tiles dynamically according to the image name is the way to go. Otherwise it's pointless. Last model I worked on had aver 100 UDIMs. I don't see myself moving UVs around and renaming all textures. That would be insane. :-)

Ok, either it's a bug or it's the way it was designed but I just realized that the ones that didn't get parented are the ones with selection icons turned off. Now the question is, if I do select something and want to parent it to something else, should it be influenced by wether the selection icon is turned on or off? Personally I think it should get parented no matter what. I did select them after all.
