Baking low poly help!

ross185

Hi guys,

I am hoping someone will be able to help me as I've tried multiple ways to get my high poly bake into my low poly without skewing or distortion...

I've looked at my vertex and face normals, softened the angles, added more geometry, redone the UV's multiple ways but nothing seems to work...

So last try is to see if someone has an idea on here! The annoying thing is I've done it before and it worked perfectly but that was a test so i deleted the files.

The main problems is fairly obvious, it is the bolts that are stretched and the tire tred is jagged/not straight?

Any help would be life saving!

Thanks,

Ross

Can you post a pic of the mesh and UV map?

If your tire treads aren't aligned, I assume either your UV's aren't 100% straight/aligned, or your low poly isn't overlapping your high poly properly.

Also, check to see how your projection cage looks. Maybe tweak those individual vertices. You want your cage to be very close to the mesh but not too much that the rays can't shoot properly.

How does it look on the geo though?

Hey,

thanks for getting back so fast, I may have to look at the cage like you suggested as the UV couldn't be much straighter for the tred.

I've also added what the Geometry looks like. I've added edge loops into the sides to see if that would make a difference but it didn't... as previously the wheel had less edges.

This is with the normal layered on top of the UV.

No, what does the geo look like WITH the normals applied?

+1 to what slosh is saying, try testing it on the mesh in a real-time viewer like marmoset toolbag or unreal etc...

Unless you are getting something crazy going on with it applied to the mesh, the bake looks absolutely fine to me.

Are the bolts on the HP normal 5 sided nuts? need pix of the HP, and the low poly with the Normal applied.

Normal information can bake "crooked" if your UVs are distorted slightly (square UVs when they should be more trapezoidal, for example). Like everyone else is saying, always check it against your mesh before making conclusions.

Here it is with the normal map on the geo... annoyingly I tried a new uv/redo of the low poly and turned out worse

You have a great deal of the tire mapped in a strip when only the tire tread should be mapped that way.

Also for the nuts I would drop a lot of that Geo in the middle where the nuts are and have the vertex normals point straight outwards (x axis in this case) so you don't have skewing, hell with the Geo you save you could model the nuts quite convincingly.
