Hi everyone!

So I coloured a surface with hydrophobicity and exported it to .obj. What happens is that this surface is exported with thousands of materials, one per color value. Most 3d applications have issues opening this file with these many materials.
I tried opening this in blender and other apps and it just crashed.
What needs to be done is for this surface to be exported with just one material and these color values exported as a weight map. Obj supports this and in a 3d app (blender, lightwave, houdini) we can use this weight map to drive properties, such as the color that we can feed into the single material.
Thanks!
Luis
