Does a polymesh node require a matrix? Geometry in question is baked but does it still need an identity matrix?

'kick -info' for polymesh node shows:

MATRIX[] matrix (empty)

Render log shows:

WARNING | <name of polymesh>: shape has degenerate (non-invertible) matrix transform

Using version 5.1.0.1

Thank you!

If I delete the matrix from an ass file and kick the ass file, I don't get that WARNING.

Same if I put matrix NULL

What do you have for the matrix?

Since the geometry is baked, a matrix is not specified in the assfile, so it would fall back to the node's default for that param.

Thank you,
