Certain models don't animate in GUI #494

Open moofMonkey opened 1 year ago

moofMonkey commented 1 year ago

Describe the bug

Exported glTF model animates correctly, however GUI doesn't seem to apply animations at all. idle idle $cave_head_stone_fracture_new$ $cave_head_stone_fracture_new$

What Valve game does this happen in

Aperture Desk Job

Reference file in a Source 2 game

Only one reference file so far, models/cave_office/cave_head/cave_head_stone_fracture_new.vmdl.

Expected behavior

GUI should actually animate the model

What version of VRF are you using? On what platform?

master, 6b14a61 so far

The model VBIB lacks BLENDWEIGHTS, so it multiplies by zero in the vertex shader.

BLENDINDICES is RG1616_SINT, so is it two components or what?
