Shadow mapping is the common technique for rendering shadows. Quick Look. It's traditionally used to compute shading, but you can output whatever color you wish. I'm new to shader programming, so I decided to use Unity's shader graph for that. For example: smooth changes to alpha or emission are not working, it's more like 1 (object visible) and 0 (object invisible) there's nothing much in between. 99. URP and HDRP however have a concept of batching that's supposed to replace (the need for) GPU instancing. obj file from MagickaVoxel): 1. So its not neccesseraly going to be faster in vulkan than in unity. If there is material information in the vox file, then setting it to some information material already works. Geometry shaders are a great tool for simple (often-repeating) shapes, like cubes in a voxel world or grass leaves on a large outdoor field. The ocean shader and the skybox were the first things I tackled - made them fit my stylized/low poly style more. A compute shader can then transform this data into whatever data the actual rendering needs, most likely id's or lookups into the virtual textures. This asset uses a combination of compute shaders and a geometry shader to create map chunks with Perlin Noise and display them quickly. Voxel terrain is probable the most common application.
