Water over rocks
Posted: Tue May 09, 2017 3:10 pm
I have been trying to teach myself more about the Octane material system and how the different texture nodes work. And so I have been trying to get as many different effects using as few elements as possible.
This little river scene was done entirely from within Octane SA and it uses just a single LUA generated plane.
I baked an 8k displacement map from a procedural texture and then used that to extrude the rock shapes from the plane.
To isolate and color different heights of the extrusion I used some mix textures and gradient node.
The water is just a procedural texture input to the bump channel of a specular material, which in turn is mapped to the displaced plane via a mix node.
Finally I used the AnimateValue_SG script to move the water’s specular bump coordinates along Z axis.
Some motion blur and minor color correction added in After Effects (I guess it is not possible to create motion blur in Octane from an animated UV property).

FYI: I have the Blender Plugin but when learning how things work generally in Octane I prefer to use the stand alone version. That we could animate quite a few properties with these LUA scripts is a great bonus! Though I’m really looking forward to the Blender plugin gaining the ability to import ORBX files. That way I can set things up material wise in Octane and export to Blender for more sophisticated animation control.
