Normal Maps Error - Please Help!

Cyph3r

Hey all, getting back into 3D after a long time away... This is probably a super noob error but with my normals I'm getting this:

no normals:


normals:


I've checked the unwrap, there's no inverted faces or anything... Can someone help please?



Not only is is the corners of the case, but the ridges on the bottom of the case have baked out fine, but on the top of the case, they're inverted(?)

Thanks

Are you still getting that error in Marmoset or are you only looking at it in 3DO. It may just be the viewer.

I haven't tried Marmoset but even just looking at the normal map you can see it's wrong, so surely that would translate over to other viewers? I'll give it a try in Marmoset/UE4 tonight though.

if you post your files I can take a look at it

Doesn't like there is any padding on your normal map? (can setting padding pixels when you are baking the normal map).

Also make sure all your vertices are welded too (This still happens to me!).

Depending on your topology too - it might worth re-unwrapping the UVs for the bottom of the case so that its one UV shell too?

This looks like you need to invert the green channel of your normal map.

Padding was set to 16!

All vertices are welded as well. I did reunwrap the pieces as well and it had the same result? I'm at a complete loss as to whats going on

James O'hare right? (Your profile picture is familiar). Long time no speak!

I shall try inverting the green channel when I get home.

*EDIT*

You were bang on, inverted the green channel in max's RTT dialog and it's solved the issue!
