I have a colour image that I wish to use as a displacement map. But is there a system in Max to allocate colours to variable degrees of strength? What I mean is I want the red in the image to be at 20% strength, and yellow to be at 10% and maybe purple to be 80%.
as per my experience with max you can not override colour sensitivity in max.
instead u use whatever colour you want in diffuse for rendering purpose and for displacement purpose.....u do this
1. take your diffuse colour map in photo editing app
2. apply black to white colour banding with different gray shades as required ( I hope u know that, gray values are used for all other slots for calculations other than diffuse.)
3. apply gray intensities as per your required % values
4. apply that may in displacement or whichever slot you want.
