Multi greyscale image to mask multiple textures

Hello there folks.

I’m worknig on a close to realistic earth/planet texture at the moment. I know there are nasa earth images for such an occasion but want to be able to control the texture myself.

I have been working with a black and white jpg image and am able to get two types of textures to work on each of the colours fine. I want extra detail in some areas and not others so I can control green areas and dry dessert areas procedurally. Is there a way to set the texture up so I can import a greyscale image with solid areas of upto 4 different shades between black and white and get different textures/effects on each of those shades?

I’ve tried all manner of solutions but can’t seem to split the textures over any more than two shades on an imported image. At present I’m just importing a simple white background image with a black box and a grey box on it. I can affect the white background to work as a texture but both the black and grey boxes come out the same texture, I can’t seem to split them easily.

Any advice would be greatly appreciated.

Think i might have figured out a solution using RGB and black to seperate out all the sections I need… Let’s hope I don’t need to use more than four colours or I’m really stumped.

Please refer to the video

Apologies for the rediculously tardy reply to this, Many thanks for the video. I’ll check it out. Think I might have found a useable solution to the problem in the end… albeit a convaluted one.

Thanks again

In case you need some other help in this, I set up a Cycles and Eevee friendly version of the old 4 Color Splatter shader.
