3ds Max 2012 Normal Map madness, please give a hand :)

kostyasazonov

Hello guys!

I've just installed new Max 2012 and can't understand - what is it doing with my normal maps?
So here is screenshot of two renders with same model, quality, prefs etc. First is Max 2011, second - 2012.

3ds Max 2012 does something mad with uvs, realtime render shows exactly same problems as other. The seams start affect lighting on surface a lot. I can't undestand the problem with new Max.

Please, help me if u have some time, guys!

I also rendered it in Marmoset. I flipped Red&Green and normals became fine and proper.
When I inverted Y axis, it started look like in 3ds Max 2012. In Max none options (flip/swap in material editor) can help

Does anyone know where the problem is? Is something wrong with mesh or may be uv's?

im quite new to all this but i have had the same problems with a few of my models where they look fine until the normal map is applied
have you tried rendering it out in UDK? i found that the errors seemed to become none existant with the UDK engine

3ds has the green channel inverted to match udk, but that's the opposite of most other engines, what did you bake the normal map in?

We discovered this problem recently, ChaosEidolon found the solution... disable Gamma Correction. We should probably spend some time understanding gamma, to set it up properly. But for a quick fix, disabling it solved the problem with normal maps.

Gamma/LUT fix works. I read help, it is thing for video guys, seems to be useless in assets for games. And after disabling LUT - normal map displaying not so ugly in MAX.

Thanks a lot!

you could also just flip the green channel in Photoshop.

They changed the standard settings for Gamma/Lut in 2012 that´s why it works in older versions out of the box.If you save with an older version and open it with 2012 it will even ask you if you want to keep the gamma/lut settings(disabled) from the file or use the activated ones.

Not sure if it was ChaosEidolon who found the solution but that´s the solution for many fucked up things in 3dsmax(Textures beeing to dark/bright,Normals looking wrong, lighting totally fucked etc.)

Yeah, don't know about the bigger picture, but he did offer the solution here in our studio.

LUT is the first thing i turned off in 2012.

Victory!

Ran into this awhile back before as well. Just to let anyone know exactly where to fix the issue, go to Customize > Preferences > Gamma and LUT tab > Uncheck Enable Gamma/LUT Correction.
