Octane Composite Material Tweet

[Greggers]

Would anyone have a link or knows if there is an issue with the composite material in blender octane latest build. I need to create a tiled texture but with variations of it using masks across a plane. I heard vray has a way of doing this in max but when i looked for an octane equivalent i found out about the composite material. I cant seem to get 2 different materials to be separated via a mask texture, I see no masking in the render.

EDIT - I plugged the mask in the wrong node. Silly me.
