Normal map projection sucks!

heyba

Hello everybody!

I'm Cg artist since 7 years, i work in the realistic photo render.
Now i'm tying to learn the worklow for a games assets, i've just create a Boots 3d model in full poly and a low poly for the projection (normal map) but i've a big problem with that.
 i join a few images for explain my problem.
In fact the normal projection dont doesn't work. What is a problem? my lowpoly? or all?

Soft: 3dsmax / Xnormal

Sorry for my English!
Thx!

It could be so many things, it's hard to tell. Probably your uvs are wrong.

Thx for your reply!

It looks like your smoothing groups could be causing problems. Make sure you have a hard edge at every 90 degree angle and uv border. Also your uv layout could stand to have fewer pieces and a bit more spacing between certain edgeloops around the base of the boot

Are you using a cage? If you're doing a cageless bake, it probably can be your settings too. What are you using for baking your normal maps?

Thx for your help!
This is my smoothing groups (the color ID match to smootinhg groups number), it's correct?

heyba

Yes i'm using Xnormal with a cage (low poly model + Push)

If I remember correctly, only using the push modifier and exporting it does make some bugs. Try to do a cageless bake, see if the result gets any better, and if it does, then your cage is the problem.

It looks like the rays are not hitting the soles of the boot. I would check the 3D viewer to make sure that the highpoly parts are aligned correctly with the low.

Or try baking in Toolbag 3, these sort of issues are generally easy to identify.

In general, I would say you have far too many UV islands and smoothing groups as well.

Thx for your reply, i finally succeeded some adjustement again!
And this is the next: the cloth marvelous designer high poly and baking normal to xnormal
