Need help with alpha blending issues. in Mesh Posted 8 hours ago On 1/18/2020 at 3:23 PM, Nergal Ninetails said: The problem your facing is called Alpha Z sorting, Essentially it's the draw order of the mesh itself causing the Alpha Z sorting problem, Right. The key thing to realize is that, for alpha blending, depth sorting is for the entire face, not per pixel. If you have something with a complicated shape in near-contact with something else, like hair, head and clothing, it's ambiguous which face of which object is on top. For hair vs head, you can kind of make this work by making the hair partially transparent, with an alpha value around the middle of the range. With alpha masking, depth sorting is per pixel, and the GPU does it. But alpha values are reduced to "on" and "off", using the threshold you set in the texture pane of the edit window. So the right stuff is on top, but the transition is abrupt. To get a good sense of this, make a simple X of two intersecting flat surfaces, with a texture with an alpha channel on each. You can do this with prims.View this with all the combinations of alpha blending and alpha masking. That will let you see how these modes work.
