Hi Connor, here's a starter:

Fantastic! I'll implement this now! Let you know how it goes.

Choice, Patch works great. However I get a crash. Im using jit.gl.render instead of jit.world. So whenever I enable a light with "@shadows 1" it crashes the patch. My Max log consists of stack underflow.

Any ideas?

please post your patch

Take a look, let me know what you think. I think this is partly because I'm using a matrix output to affect the triangle polygons. This could be the issue?

don't use jit.gl.render for drawing, instead use jit.gl.mesh (i know our material is outdated in this regard)

Wooo! Cheers Rob you have fixed my problem!

is there a way to maintain the shadow rendition on a surface materialized with manual heightmap_modes? A jit.gl.mesh seems to only support shadows on its surface when operating @auto_normals 1, using manual heightmaps and normalmaps on an attached jit.gl.material makes the shadows disappear. Any flag I can tick perhaps? Appreciated!

not currently but there is an open feature request for this functionality and I hope to look into it soonish

Thank you Rob, looking forward to it
