Title: Normal Map Display problem in keyshot
Post by: clau1000 on August 15, 2013, 10:50:05 AM
Hello,

I am trying to get normal maps to display properly in keyshot, but they are acting pretty strange, and there seems to be not much of a difference when the Normal Map option is checked or unchecked, under the bump map texture type, using an advanced shader.

So I made a simple example to test the difference between maya normal map display and keyshot. It's basically a half sphere on a plane (highpoly geometry), that is baked onto a plane (lowpoly geometry), using Xnormal. Here are the results -

This is the baked normal map, showing the sphere :

Plane with normal map applied, rendered in maya viewport (with high quality) :

Plane with normal map applied by using an advanced shader, under the bump texture type, with normal map checked :

Obviously keyshot is not displaying the normal map correctly. Please help, thanks in advance. I have also attached the obj of the plane for testing purposes.
I am using Keyshot 4.1

Does it look the same from the other side of the plane too ?

Yes, it looks exactly the same from the other side too.

Very strange, will have to wait for an expert opinion on this one.

We are looking into it.

There was a bug (has been fixed now), where you would not be able to toggle into a normal map (so it would look like a bump map, which is what you are seeing). You can send an email to beta@luxion.com if you want to try a beta KeyShot 4.2, where this is no longer a problem.

we have the same problem in our keyshot. but it is the newest version (4.1.35).
could it be, because it is still a trial-version?
