1 sided projection

[atoyuser1]

I'm trying to project a material on one side of a plane, with another on the back

I know I can do this using the Side node and Mix Texture mode (following Octane's documentation), but I want to use a base layer, with the front side on top of it

It produces a blank back to the plane:

Is there a way round this? I've tried to use an imageTexture node with alpha set, but that didn't work either:

I've attached my C4D file in case anyone wants to take a look

Hi,
you are working with two different materials

There are two ways:

1. Transform both materials into submaterials:

then copy one of the in the other one and connect the submaterial to the new Composite material created, using the Side node in the Mask:

2. Add a Diffuse Layer to one of the material, and use the Side node in the Mask:

Here is the scene, on the left the Composite Material version, on the right the Layered Material version:

Finally got Octane running again - Side node on the opacity worked a treat! thanks
