A ChunkMaterial can't be derived from NodeCore, so this doesn't do
anything. You'll have to check for Geometry and get the Material from
the Geometry.

^^
You need to use the Mask, not the ID for begin/endEdit. this applies to
all cases, I hope you're not doing this everywhere in your program. Then
again, I can't think of any case where you would need to use the Id, you
can probably just replace Id with Mask and be fine.

That is strange. Did you begin/endEdit the BlendChunk when changing its
parameters?

Try the Mask, and make sure you begin/endEdit the BlendCHunk. If that
doesn't help we'll have to look for something else.
