How to apply colored displacement?

I downloaded a Surface Mimic texture. It is comprised of a grayscale displacement map, plus a color-texture.

How do I apply both to the same object, so that they match 100% perfect?

What I tried already:

  1. Applied the color-texture to the material assigned to the object (terrain.3dm). As the object is a piece of terrain, Surface Mapping seems most appropriate. Not important at the moment: There is distortion in one direction, which could be removed by cropping the texture to be a square.

  2. I ran ApplyDisplacement on the object, selecting the displacement map. The result is that I see the displacement. However, now the color-texture is replaced by a uniform brown, which is not the color of the material sans texture.

Note, I need this for 3D printing. So, a bump map is not an alternative.

Felix, can you please also post the images used?

@Pascal, see the free sample behind the link that I posted earlier. The images are PSDs. I converted them to JPEG using Xara Designer Pro X10. I’m afraid, I’m not allowed to post the JPEGs here without violating copyright.

Yeah, that’s fine, I see a similar result with my own images. Not sure yet what to suggest, still poking…

It looks like Surface mapping is not working with this process - but the default, with no special mapping, is UV and this is the equivalent of ‘surface’. If I open your file, assign a material with a texture and then apply Displacement, not having done anything ith mapping at all, it works - I get both color and displacement. As soon as I apply surface mapping the color goes away; Planar is OK. So it looks like something is amiss here.

Thanks a lot @pascal! When I posted this I didn’t think that it may be a bug. I just thought it’s me being too lazy to read all the documentation.

Aha! The truth comes out!

What is an easy way to reset to default?

Of course, I can export the geometry, then delete the surface, then import the exported geometry. That would give me a surface with default material properties. Out of curiosity, I wonder if there is a quicker way.

Hi Felix - RemoveMappingChannel - enter 1 as the channel to remove.
