I do understand that the triplanar node rely on the world/object space position and displacement map alter the position, hence we wont be able to use triplanar map for displacement. (I guess it is the case)
I am trying to do a pre-triplanar solution that I calculate the triplanar blend weights and xyz axis uv assignments in Vex and passing the information through the new attribute solution. However, it still doesn't work. It looks like the vertex(point) attribute reading node is executed after the displacement node...
Is there any workable solution?
