Web19 hours ago · This time, the creator showcased a neat parallax shader created with Cycles, which enables one to create a detailed 3D parallax effect and fully dynamic self shadowing with any lighting. According to the author, the shader supports various texture sets, including procedural textures, and works with 3D decals. WebOct 19, 2024 · Texture fetch is an expensive operation. We want to minimize the number of fetches as much as possible. The good news is that our volume is static. The voxels are generated when we create our 3D texture (section Generating a Volume). It’s thus possible to pre-compute all the gradients and save them into another 3D texture. chin\u0027s 8t
