I am looking for a way to transform a mesh according to a texture, as I do in Unity with the addition vertex function of a surface shader. I am trying to use shader chunks to modify the vertex shader of the standard material, but I do not know which chunk or variable I should use.
I do not need to take animation and rigging into consideration.
Thanks for your attention!
Hi @Aryous,
Usually the chunk to modify for controlling the vertex position is the transformVS:
You can modify either the localPos or the resulting dPositionW.
Check these examples on how to get started with shader chunks:
