Easy texturing question

[Builtdown]

Hi,
This should be really easy, but I suck with node texturing and would like to know how to do this:

I have a UV´d box with a red glossy material.
I add a black and white concrete texture as a UV texture to it.
I would like the box to stay glossy red but add only the white parts of the concrete texture to it as with Photoshops Screen-blending mode.

How do I do this?

Thanks!

Hi,

You have several nodes to add, mix or multiply textures that can be used also with an Octane RGB node to process any texture map using an RGB color, as you can see in the attached image.

Thanks,
