Normal map issue

Moltar · Nov 2015

A perfect circle is appearing in part of my normal map for a Scifi gun im modeling. There is no reason at all why this is happening, I cant figure it out. Im using a cage which is correct, the HP is not protruding through the cage nor is there any geometry behind it that would project onto the handle.

Edit - The Uvs are also fine.

Anyone have ideas as to why this is happening?

What software for modeling, for baking, for rendering? Show the normal map pls? Show the UV wireframe?

Moltar · Nov 2015

I used 3dsmax for the modeling. Headus for the UV packing and Xnormals for the baking.

Sorry, should have provided this info the start with.

Thanks for the info.
Floater? What does the HP look like in the Xnormal preview?

It's not letting me screenshot the model in the 3d viewer, even when I hit F8. But it looks completely normal with no floaters.

Today I took the gun handle padding out of the HP mesh and baked a new normal map. With the padding gone there is no circle baked onto the actual handle so Im thinking it's something to do with the padding mesh/geo?

Sounds like a padding bug then. You can simply pad in Photoshop instead.

Thanks for trying to help Eric. I've fixed thee issue now by modeling a new pad for the handle. I thought I would ask here first before I done anything like that just encase there was an easier and faster fix.

You should consider sending the erroneous model to @Jogshy to see if there's a Xnormal bug that needs fixing.
