Experimental idea for EXR2Mesh

[Igors]

Hi All

Look at first attachment. Both terrains have same geometry. The difference is that left uses vertices normals, right one - bumped normals.

Second attachment shows the trick. First "ResetNormals" shader turns all surfaces normals up. Next (top) bump map is same EXR image that used in plug-in with Bump Factor = Height (in plugin).

This technique is not perfect because bump is a cheap/trick. Typically artifacts appear as black outlines at places where model/normal are mismatch. But it's simple and interested to experiment

Good luck :rolleyes:

Hi Igors,

Thank you for the Shader. I cannot import my .exr image into bumps and displacement.

Where do I go wrong? :blush:

Hi, Richard

You did nothing wrong, it's an old nasty bug in texturing, not related with concrete shader/image.We see that one of texture's params is invalid and blocks further textures adding, but we don't know what steps/actions caused this. If you can reproduce how to get such situation - it would be very helpful.

It's easy to avoid - just delete shader and apply it again, all will be fine.
