Export mesh as greyscale image?
show user profile  magarlick
Dear all

I have created a terrain in Max using a variety of functions. Here is a shot:

https://www.dropbox.com/s/9l7907ecirxytpv/Untitled-1.jpg?dl=0

I want to edit this terrain in Photoshop, which I am much more familiar with and which will give me a lot more control. So what I am trying to do is render the terrain in Max as a greyscale map, such that height corresponds to shades of grey. I then want to import this render into Photoshop and edit it, then bring it back into Max to use it as a displacement map to create a surface. Trouble is, I can't see how to render the heightscale map. I have tried applying a Top/Bottom map to the mesh, with black at the bottom and white at the top. Blend is 100 and position is 50. I thought this would colour the above mesh so that it's black in the troughs and white higher up. It doesn't nothing of the sort. Instead, this is the result:

I've looked at Render Surface Map, which doesn't do what I need. Seems like this should be a doddle but I can't find it. Any help appreciated.

M.

You could try a standard gradient map, with the right UV mapping it would be fine.

Thanks, Dave, I just about figured this out before your post. Very much appreciate your reply, however. All the best.

Alternatively, you could render a depth pass through an orthographic camera.
