First, for my first message, i want to thanks all the babylonJS developer for their awesome work !
I recently tried the Terrain Meterial for generating a custom terrain with a mixmap...
All is good so far, i even found a process to generate a mixmap with Blender and Cycles from a heightmap (I attached an image to the post for people who want this).
I still have an issue with the shadows or the TerrainMaterial, started though i was making a mistake, because my scene is more and more complicated,
but i reproduce the bug on the playground, and i got the same error :
Unfortunatelly i'm new with WebGL, BabylonJs and all this stuff, and i can't understand nothing nothing about this material, it's way too more complicated for me...
Can someone tell me if it's a bug, or if the Terrain Material maybe cannot support shadows yet, or perhard i just made an horrible mistake XD
