Material ID's breaking with frame interpolate

Deprecated XMesh Alpha Bug Reports

VRay (but the issue is visible in the viewport also)

I just read Bobo’s post about why not to use frame interpolation, so this won’t be an issue for us, but I thought I should report it anyway…

Create an XMesh loader and load a sequence.
Assign a multi-sub material. Everything looks good.
Change loading mode to Frame Interpolation (or Subframe Interpolation) and it still looks ok.
Change to another frame and material ID’s are lost (all faces are material ID 1).
Change back to Frame Velocity Offset, it’s still broken.
Change to another frame, now it’s ok again.

Confirmed.
It also fails to load the Smoothing Groups in those two modes.

Thank you for your report!

Per-face channels, such as material ID and smoothing group, are currently missing in frame interpolation mode. This should be fixed in the next build.
