Here is an OSL projection shader that implements Parallax Occlusion Mapping. This is a way to simulate displacement without actually adding new geometry.
Compatibility: Octane 2020.2 or higher.
Very basic test scene, experiment with your own materials and textures. Manual setup:
1. Add a Projection node of type OSL projection and point it to the OSL file.
2. Plug the displacement texture into this node.
3. Set the projection on the displacement texture node to "OSL delayed UV".
4. Use the parallax mapping projection as the projection for any texture used on the material.
5. Play with the Depth scale value to tweak the effect.
One of the differences is that the one here uses a texture node as input instead of a file name.
Don't hesitate to send remarks, usability suggestions, bugs, advantages/drawbacks compared to Texture or Vertex displacement, etc.
