[SOLVED] Shadows don't appear with imported model

[pspeed]

@yaRnMcDonuts

I am also noticing that any models that are animated in the .vert shader (like grass or trees swaying in the wind) will always cause artifacts

If they don’t have a preshadow technique then they won’t render shadows.

But for example, SimArboreal trees render shadows just fine and they animate the vertex shader for swaying in the wind.
