Thanks for letting me know - and the link to the limitations page.

Joe Williamsen (jwilliamsen) added a comment to T67408: Cycles Motion Blur Intermittently Renders Rigged Mesh With Severely Stretched Triangles.

Thanks again for the information, Sergey. I had no idea that you could play back subframes - this does show that there is some weird mojo happening in this animation, sometimes with the armature doing a full 360 degree rotation in one frame. I'm guessing this is due to something breaking in the FBX import of the animation, as once you look at the curves (focusing on the Hips bone) it's obvious what's going on.

Thanks for the reply, Sergey. This is good information ... that I've never run across. I went ahead and did some tests to see what worked and what didn't, and I've found that it's not necessary to disable AutoSmooth - but you DO have to click the "Add Custom Split Normals Data" button under "Geometry Data". This is a detail that I don't think I've ever run across (not that I'm a Blender Guru), but it seems important enough that there should be a pop-up warning when someone goes to render an animation with Autosmooth enabled, without Custom Split Normals Data added to a mesh. The reason behind this is that anyone coming into Blender/Cycles who doesn't know this requirement is going to write off Cycles as a renderer almost immediately - *I* was getting close to giving up on it. The difference in blur quality is dramatic:

That would have been nice if that's what was causing it ... but it looks like that's not the (only) issue since after cleaning up the model with the 3D print tool, I still get the same rendering artifacts:

Ah - Thanks - what I get for following someone else's example without really LOOKING at it.

Joe Williamsen (jwilliamsen) added a comment to T60733: Subdivision Surface Performance Degrades Markedly With Non-Quad Meshes.

Agreed - it's very likely it's the same underlying cause. FWIW, I didn't see the same behavior in 2.79, so it's something new.

I can confirm this on the Windows build as well (failure to import OBJ files) - Windows 7 X64

Joe Williamsen (jwilliamsen) added a comment to T53821: FBX Import Fails to Import (some) rigged FBX Files Correctly.

I think it might have something to do with Softimage's bones having "roots" and "effectors" by default. If I export the FBX without the roots and effectors, I get a different result - still broken, but different.

Absolutely! Anything to bring Blender's FBX compatibility up to par. I'm seriously considering migrating to Blender for my work and FBX compatibility is critical for me. This would be a huge PLUS in Blender's favor :)

Sorry - that RAR is a Version 5 archive - incompatible with version 4 (so you need the updated WinRAR).
