its simple test for mud and snowtrails. i trying to recreate to old “renderman-deepopacity-displacement trick”.
instead of using a displacement shader with craps depth-information from a light. i rendering sperate passes and use nuke with timeecho node and expressions to create a animated displacement maps for the trails.
i am trying to create with python a one-renderpass workflow like with the smart rendermanshader setup in maya
the displacment map out of nuke
