Here’s a working patch demonstraton. Its a modification of the ‘dynamic model from noise’ helppatch with UV coordinates and the tangent fix.
Note that it references directly Stride.Graphics.dll
Includes textures for a test material for normal mapping
In case any future VL.PolyTools user stumbles across this thread in future I added a hidden ‘Calculate Tangents’ option to the PolygonPlane and PolygonExtrude nodes. And new helppatches about the entire topic of texturing these 3D poly things.
