Problem with CanvasTexture and DecalGeometry

Hello, I have a problem showing the canvastexture only once, instead the texture is repeated on the back side as a mirror, I want it not to be repeated and occupy 100% of the geometrydecal (mesh body only)

Depends - how does the UV map look on the model?

What is the size parameter of your decal? It the decal projector is too big, it will go through the back side. Try with a size that penetrates the front side, but does not exit from the back side.

Muchas Gracias, I found a solution with position z of decalgeometry; 0.5 frontside and -0.5 backside (solution only works in my model and mesh position), thanks
