I am trying to use a stencil using an Alpha Mask so I can place a typography (png image) to a 3d model. I tried it a few days ago an it was all fine however i made a new mesh and now its seems that I cant make it work.
I made two basic bsdf materials, along with a texture with 0 alpha level, the texture attached to the secondary material. The texture (material base color) is also connected with the fac of the Mix shader. The Brush is set as "Mix". I also checked to flip normals in case I have been painting on the inside of the model.
