xnormal normal map generation problem

art73

Hi All

I`m trying to convert an hifi amp object in xnormal and i cant seem to get decent results.

I`ve uploaded 3 images. The first is done in xnormal without a cage, and its missing details like the logo and head phone jacks.

The second image is with a cage i created. That has those missing details but the inserts where the volume dials have turned into moon crescents.

The third image is a maya transfer which seems to be the best. But wondering why I cant get it to work in xnormal?

Any ideas?

Thanks

Your fine details need to have beveled edges for the normal map baker to catch them. If they are totally flat with 90 degree edges, when the baker looks straight it it, there isn't any information to record. Normal maps can't bake depth, only changes in direction/angle.

The skewing issue is covered here: http://www.polycount.com/forum/showthread.php?t=147227

You should probably look into some basic normal map tutorials as well.

The Maya bake still has problems.

The normal map is missing parts of the round shapes. The high-poly model is probably not built well for normal map baking.

There are large gradients across the normal map. This will cause shading artifacts when the normal map is compressed in a game engine.
You're making me hard. Making sense of hard edges, uvs, normal maps and vertex counts

The bake does not have anti-aliasing enabled, so we see jagged edges in the normal map.

There are skewed details in the normal map. The low-poly model is probably not modeled well for baking.

Also I see some long triangles in the normal map. This could be from duplicate overlapping surfaces in the high-poly model, or some other wonkiness there, check the model carefully. It could also be overlapping UVs in the low-poly model. http://wiki.polycount.com/wiki/Texture_Baking#UV_Coordinates

Thanks guys. I did bevel in the volume dials inserts to make sure they were picked up by the normal mapping. Will check the other details out.
