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

  1. Cool!
    Can you have it bottom out after a certain depth value to reveal ground substrate or simply flatten out? That would make it even more believable.

  2. its easy to do… you create add extra noise in nuke and display it in realtime… you almost can sculpt the animated the map… its very flexible system
