Height map from node material

Hi all, amazing library!

I have a ground mesh with a node material that modifies the VertexOutput node to give the ground variable height, and it’s been working great. Now I want to add collision detection, but the ground’s bounding box is just a flat plane. Is there a way to generate a height map from the vertex output of a node material?

Unfortunately you can’t retrieve on the CPU side the updates you have made in the vertex shader (using a node material or a built-in material). Those changes are only known to the GPU side.

ah okay thanks
