After some further playing around I discovered what Dec 3, 2019 · I'm trying to update the values of a groupshared array in a function, but it has no effect, however when I take the same code out of the function it works as expected. Saves the given properties as part of the material asset, and uses the values stored in the material asset during rendering. The simplest one is to always initialize the array at some size larger than you need, or at some max size. EDIT: It looks like You're using 8 textures A shader model is a shorthand for a group of GPU features; internally, it is the same as a #pragma require directive with the same list of features. However, Unity3d does not recognize my dds file correctly. If you're really intent on doing it that way, keep the texture array linear and convert the albedo in the shader. 1. Dec 31, 2014 · I know that I can sample textures in the vert shader with tex2Dlod, but I can't seem to find a texture array equivalent.

I already read some forums about surface shaders, checked the documentetion multiple times and can't figure out whats wrong. Obviously, you can do that only if the number of possible array sizes isn't to high. For example these shader A program that runs on the GPU. But on large like arrays like > 128x128x128 it becomes a pain.
