Re-baking lights changes these coordinates each time. 5) before the texture scaling is applied. When you place a model in that folder and reimport it, Unity will calculate soft ambient occlusion specialized for trees. vertex - input [0]. These are added by Unity automatically and can be used to tile or offset the texture coordinate if shader allows. Ready to work: (1) Create a new material and name it SingleTexMat. An unlit shader for unity covering all the common use cases without any overhead for the features you don't use. Next, because I want to reflect the result of the projection to the texture, I replace the main texture with a RenderTexture at first, then call Graphics. The shader is simple as well (just simple projection texture mapping) and I posted it below. Now, all the clouds are moving in sync, but I'd like to have them move a little more random. However, the logic applies to other engines, especially when it comes to shaders and scripts. • Clipping plane offset - X - vertical offset of reflection; Y - near clip plane; Z - far clip plane (affects performance). 3. public class Example : MonoBehaviour { // Scroll main texture based on time. The color is applied to your material (red). This scene does not use any textures or animation assets; everything you see is colored and animated using Shader Graph. However, vertex Shader constant register #255 (c255) is now reserved by Unity, and all vertex shaders get two instructions automatically added to do the adjustment. Learn more about bidirectional Unicode characters. Tiles and offsets the value of input UV by the inputs Tiling and Offset respectively. Shader works perfectly, it can coloring, thickness, all that you need. 5 . Generally, we will grab a complete screen image (or texture), use the Shader to process its pixels on the GPU, and then return it to the Unity renderer to render to the screen, which is a post-processing process. Trees must use the Nature/Soft Occlusion Leaves and Nature/Soft Occlusion Bark shader. Of course we get tiling and offset controls for each texture that we add to the shader.
