How to mix two textures by "screen". Tweet

[R_Flash]

Hi. I need mix two raster textures in material by "screen". I find only multiply. Cinema "layer" work with errors. Thanx!

did you see mixtexture? It's for mixing two textures. you can put any other texture to amount slot or just use slider of amount

Indeed! With the base texture as texture 1, a RGB white as texture 2 and the "screen" texture as amount in a MixTexture node, you'll have the same result as screen fusion in Photoshop.

Thanks guys! It`s worked

atome451, could you be so kind to provide an cinema scene with two textures mixed in "screen" mode.
I got two textures one is "asphalt" and the other is " white road marks", you said that "screen" should be placed in the amount channel, but there's no screen in octane
Thanks

Hi

A while ago I made a few blending mode setups. There's much more than just screen. Check out the scene files. I hope that helps.

Edit: also new 3.06 test release has this functionality built in so setups like this will not be needed in the future.

Nice but it's easier to do with OSL nodes anymore.

Cool! I don't know much about OSL nodes. How would setting up a blend mode work? I searched the forum but didn't find anything.

Something like this, very simple.
