Could Jan 31, 2021 · Hey there, I have a fairly simple simple unlit transparent shader that I would like to have write values to the depth buffer for later use in a post-processing shader. this is my result: it could be an exposure thing? When using a forward shader in Unity you can write out to the depth buffer using the HLSL semantic SV_Depth. 3, and this is the setup that gives depth based on the distance between the objects: 134216-capture. In URP the SSAO can use DepthNormals, there is also the option of using Depth but I specifically need DepthNormals… I’m working with custom lighting in ShaderGraph & currently to do that you use an Unlit URP Shader graph to avoid any sort of double contribution from lights. Although the shader code itself is the same, it is encapsulated in HLSLPROGRAM blocks, instead of CGPROGRAM. Find this & more VFX Shaders on the Unity Asset Store. cginc include file contains some macros to deal with the above complexity in this case: UNITY_TRANSFER_DEPTH(o): computes eye space depth of the vertex and outputs it in o (which must be a float2). This is an alternative to ray tracing. Unity - Scripting API: DepthTextureMode. A fragment shader can receive position of the pixel being rendered as a special VPOS semantic. Most of the shader I have so far is based off of this youtube tutorial. Please set your cookie preferences for Targeting Cookies to yes if you wish to view videos from these providers.
