Glass UV mapping issue


Go to solution Solved by Cerbera,

Hey everyone !

 

I just modeled a low poly champagne flute but I have weird issues with the UV mapping.

 

I only care about the visible polygons of the "exterior body part" of the flute (not thoses inside):

But when I load a material on the object, the material is applied on the wrong face of the polygons.

Meaning I can't see the material, but it's there.

In the Texture Tag, if Side is set to Both, I see the material, if set to Front no (it's on the back). If I set the material to Back I can see it.

 

It's like if the back and the front were reversed ???

I never had such a thing and I don't understand why it's doing that.

 

I shared the original .c4d file with the spline/lathe and the .obj so you can check if needed. Ju stry to load a material on it and you'll see the issue.

 

Thank you in advance for your help !

edit I thought It was related to the UV map but even if I set the material to another projection type like Cylindrical it does the same thing. So maybe I did something wrong with the modeling ?

Yes, your polygon normals are incorrect, as indicated by the blue colour of them here - that should be orange - select all polys, right click, and choose 'reverse normals' to fix that.

This happens when you use a lathe sometimes and is to do with spline direction.
