Greetings,

As the title says.

Example
2 textures, the main texture for the mesh & a second texture placed on top.
The second texture is simply a transparent image with color information on one section of the map.
Can this be done without the second texture being (desaturated) by the main texture?

What do you mean exactly?

To blend a texture over another:
- load both images in an image texture node.
- create a texture mix node. Connect the texture1 input to the first image and texture2 to the second.
- Create an alpha image texture with the second texture. Connect it to the amount input of the mix material node.

I guess we have another spambot.

Octane currently supports only two blending modes; mix & multiply. The mix mode has an "amount" parameter that defines how much the two textures are mixed at a certain point. So, in your case you would have to load the second texture twice; once as an RGB image node and the second time as an alpha node. You wold then set the alpha node as the amount for mixing.

This basic example image should help. Each color is its own image texture uv mapped to the cube. The red and blue colors do not mix with the yellow texture.

you currently can't layer textures in octane, so it would work like roeland wrote (using mix nodes and alpha maps)...

Thank you t_3
