image based blending?

[calmasacow]

Bump!

Come on guys no one has any pointers on how to do this?

[calmasacow]

am I not being clear?

What I need is to have a texture that that for arguments sake is a painting of blue and red.

then I have to shaders let say one is lizard skin and one is checkered.

How do I use that texture file of red and blue to control the placement and blending of those 2 shader

Please I know this is possible.

use a layered texture, put your two bump maps into it and blend between them with an alpha map

To blend the two bump maps, you could also use a blendColors node and have the blender attribute controlled by the color of your texture.
Remember that blender is a single channel attribute, while color has three channels. So you need to decide how you're gonna connect the out color of the texture to the blender attribute. For example, you could focus in the Out Color R of your texture so that only the amount of red would drive the blender. Or you could pass the Out Color through an rgbToHsv node and get the Out Hsv H to do the job. The results could be a little different. It depends on how your colors vary in your file texture. I mean, the red and blue you said you're using... Do they vary only in hue? Do you have smooth transitions like gradients? How are these red and blue blending into each other?

Good luck!
Kako.
