I'm trying to texture a model using a blank image as base, with transparency. However, no changes are being shown, which is driving me insane. Using not-blank textures works fine, so what am I missing?

enter image description here

Thanks in advance.

  • $\begingroup$ Add, only "Alpha" enabled (disabling isn't fixing it though). $\endgroup$

  • $\begingroup$ Your image is entirely transparent, that probably has something to do with it $\endgroup$

    $\begingroup$ The blank texture has alpha, and if you use Add Blend type it will not do anything to the texture. $\endgroup$

Your issue is the blend mode you're using. When you paint with the add blend mode, it doesn't effect the alpha channel at all. So if you paint on transparency, it's still transparent. When you paint on a part that partly transparent, it only effects the color, and the opacity stays the same.

The solution is to instead use the mix blend mode. Instead of adding to the values of the image like the add blend mode does, this mixes the two values.
