lucas veber (lucky3) added a comment to T62584: Linked armature issue.

Alright, I think I got it... We have to create the proxy right on the linked collection, without instancing it like we did in Blender 2.79. Fine :)

Thanks for the feedback, but sorry I don't understand. How are we supposed to fix this then?
In Blender 2.79 we can link the group (which is now the "collection") containing the same objects hierarchy, and make a proxy of the armature without any issues.

Then it's a serious issue... If the user has a custom keymap active, how an addon can know if the user has set left or right click for selection?
There's a bunch of existing addons based on selection, it would break them all.

@Brecht Van Lommel (brecht) Even if not perfect, the "bias" solution could work in many cases, it's still better than no solution at all.
As far as I understand, it's all about computing the shading ray starting slightly above the face normal. I assume you know the principle, but just in case see the page 2 of this doc:

Ok. I was thinking these were shadow issues, but actually it's not since turning off shadows does not fix the issue, it's more related to the way the faces themselves are shaded. I probably won't be able to help, I don't know how pathtracers work... Good luck with it :) Indeed, renderers such as Arnold and Guerilla have fixed it.

lucas veber (lucky3) added a comment to T37814: Artifacts in Cycles render for lowpoly models..

@Brecht Van Lommel (brecht) pardon me if I say something stupid, but... as far as I understand, this shadow issue happens when a face projects its shadow to one of its adjacent face. So isn't there a way to prevent faces to cast shadows on their adjacent faces? Dismiss them from the shadow say, when smooth shading is on?

lucas veber (lucky3) added a comment to D3869: Fix T57852: Mesh X Mirror option not working.

If you are animating, you could certainly argue that it could be useful to use a certain pivot or orientation with a certain object or bone. You might also want to use a certain transform tool with certain bones always. You don't ever want to move a wheel, but you always want to rotate it. So X-Mirror is no different. It's just a tool setting.

lucas veber (lucky3) added a comment to D3869: Fix T57852: Mesh X Mirror option not working.

Since you ask for feedback from artists, I'd support the per-object X-Mirror, as Julien Kaspar explained when working with several objects in the scene, it's the easiest way to keep it enabled for some objects and disabled for others. It may seem counter-intuitive but actually it's way more useful. I'm a 3dsMax and Maya user too, and I still prefer the way it's implemented in Blender.

I'm a little concerned by performances though, "to_mesh" creates a new mesh data block, so I thought it may be slower than the bmesh method. But maybe i'm wrong.

lucas veber (lucky3) added a comment to T54118: FBX export of armature using Spline IK looks very wrong.

The main problem in this scene is the cyclic dependency, that is likely introducing issues when it comes to animation baking.
It's a common problem with Spline IK constraints. You can open the Blender console to see the error log, and when moving the rig bones, there's also a one frame lag which is due to the cyclic dependency issue.
The dependency graph is being re-written for Blender 2.8 to avoid this (as far as I know), for now only this kind of rig setup should be used with IK Spline constraints:

Seems like a scale/stretch related issue? If so, it's not a bug, Fbx does not support it: the scale value of each bone inherit the scale of the parent bone.

lucas veber (lucky3) added a comment to T53908: Fbx export: random, weird bones rotation artefact.

While praying for this bug not to be forgotten in the dark, i've simplified at maximum the example blend file (attached) to help. It now only contains one mesh and two bones. When exporting to Fbx and importing in other apps, such as Unity, "bone2" is imported with Rot X = 179.8, instead of -90.
Rotating in Edit Mode bone2 1 or 2 degrees in Blender fixes the issue. However it's not a clean solution, it may happen in other situations. Seems to happen when a bone is making 180 degrees x-axis angle with its parent.
After further investigations with the Fbx exporter code, tracking the exported rotations values seems to output correct values. However it's the way these values are read in other app that is the problem. Likely to be an euler issue, if only Fbx used quaternions...
