What you can do to solve this is to force that the transparent objects write to the depth buffer. The upcoming HD SRP properly handles transparent shadow receiving, as did the LW SRP at one point, though they broke that recently. This determines which render pass URP renders the material in. It seems that in Unity 5, all my transparent shaders are not blending correctly. . One consideration for this shader is that the Base texture’s alpha channel defines both the Transparent areas as well as the Specular Map. I just discovered that in my case A LOT more shader flags have to be set and that only the transparent -> opaque conversion worked with the subset of flags shared earlier. - does not have automatic shadow culling at fixed distances. Then im setting the color. In this equation: finalValue is the value that the GPU writes to the destination buffer. When I test this; initially nothing seems to happen, except that I can see the material name has changed in the Inspector. Meshes make up a large part of your 3D worlds.
