Nathan Vasil (vasiln) added a comment to T73756: Animating influence of 'Child Of' bone constraint causing motion blur errors..

Just as a work-around, considering that this is related to a current, probably commercial, project, baking to visual keyframes should eliminate the weird in-betweens that happen from animated child-of influence.

Thanks, sorry for the duplicate.

Nathan Vasil (vasiln) added a comment to T79679: Unknown black lines on model in Cycles render. The fix for this suggests it's a bug or an unforeseen problem..

While it does, that's not the cause of the problem. While investigating this for OP, one of the things I did to troubleshoot it was to create brand new geometry at the same positions, with the same angles-- just two quad faces, sharing an edge, triangulated (but that doesn't matter), with vertices snapped to the same positions as the original geometry. This new geometry showed the same problems, with the same fixes, even when giving it a solidify modifier to make it fully manifold.

It's shocking to me that a few hundred units (meters) is leading to precision issues. (Applying scale doesn't fix the problem, just moving closer to world origin.) It would be easy to imagine animators that wanted to cover that distance in a single take. It's also surprising to me that Cycles is calculating in world space rather than camera space. (Maybe to maintain a static BVH or something? But then, there ought to be some options for which space it operates in.) Moving geometry is not always an option, because of things like physics (inertia is tied uncontrollably to the world.)

Nathan Vasil (vasiln) added a comment to T73942: Eevee mipmaps not respecting border mode.

Extra info: problem exists regardless of linear, cubic, or smart filtering. No problem, of course, with closest (no mip) filtering.

Nathan Vasil (vasiln) added a comment to T73941: Custom normals from normal edit modifier ignored by further modifiers.

I was mistaken about this being also true of data transfer modifier. Custom normals from a data transfer modifier are being read correctly by a displace modifier. For that matter, they're also reading custom normals from a normal edit modified mesh appropriately. In fact, this can be used as a workaround-- make one mesh, likely non-rendering, to get the normal edit modifier, and a second mesh to copy normals via data transfer from the first mesh.

Nathan Vasil (vasiln) added a comment to D1929: Quaternion SLERP/SQUAD Rotation Modes.

I know this is old, and apparently not going anywhere, but lerped component interpolation is still a problem with Blender. Particularly with abstract or mechanical animation, or when exporting animation (as what you see ends up not being what you get.) And it's one of those problems that requires enough technical expertise that most users aren't even going to realize what's happening and are going to bang their head into the wall and eventually give up.

@Sybren A. Stüvel (sybren) Please take another look. The issues remain if you connect finger1-1.R to its parent. If you need, I've done this for you in the attached file.

Nathan Vasil (vasiln) added a comment to T61031: Cycle cross-product node does not give true cross-product.

Not sure if you're asking me, but whether something's a bug or not is in the eye of the beholder. If you were to see cross3(vec3, vec3) and normalizedCross3(vec3, vec3) in some library, and both gave identical output, one or the other or both would be a bug. Even if they had identical code-- just on the basis of the name. Same as there's nothing buggy about a function named returnZeroNoMatterWhat(vec3), so long as it does what it says.

Nathan Vasil (vasiln) added a comment to T54526: Data Transfer modifier's Max Distance field working strangely.

Coming back to add that there's a reasonable workaround, which is to use a vertex weight proximity modifier to determine the distance from each vertex before the weight transfer, use a custom (constant) curve to modulate that vertex group, and then use it to modulate the data transfer. It's a bit more work for the end user, but perfectly reasonable, and it wouldn't seem unreasonable to just drop support for max distance from the data transfer.

Nathan Vasil (vasiln) added a comment to T59376: Skin modifier prevents UV modifiers from working.

I think you might not understand. I don't care about the original UV map. The issue is that the mesh will not accept any kind of UV mapping from modifier after the creation of the mesh. The problem is not that the mesh doesn't keep a UV map from before the skin modifier, that's obvious. The issue is that no UV map can be created following the skin modifier-- unless you apply the skin modifier.
