Normalmap issue

Hello community,

i have an issue with normalmap baking using the projection in 3dsmax.
I´m using an highpoly model and an lowpoly model with the uvw coordinates.

After the rendering the normal map looks screwed What could be the reason for this issue?

Make sure your low-poly object is all in one smoothing group.

An easy way to do this is to add a Smooth modifier and just click the "1" button in the list of SG buttons.
Or you could select all the faces in the object and click "1" down in the Smoothing Groups rollout.

Thanks for your reply. All of the smoothing is in group 1. It makes no difference on the normal map. What else could be wrong?

Do I have to remodel an unwrap the lowpolay model again?

Don't look at the Render Frame Preview Window when baking its totally useless and can't be trusted. Instead apply the map to a copy of the low poly and render it. That will people a whole lot more.

It looks like the UV's on the low are un-welded or jacked up in some way. Can you take a screen shot of your UVW Unwrap Editor Window? I've seen this happen a lot with meshes coming out of older versions of Zbrush. You might want to just re-unwrap the model in max if they're all screwed up.
