I guess something is wrong with material but I have no idea how to add gradient to blue color. I have a translucent material that needs to darken things by distance, but the only thing that does that is scene depth, which ends up using the camera instead of the object itself.

I’ve programmed UI materials that utilize SceneTexture nodes to create transparencies based off SceneDepth and CustomDepth/Stencil settings, but I’m running into a problem where the resulting mask is not I mean the scene depth texture literally gives you the distance to the camera in a buffer, so if you plug it into a smooth step with values like 500 for min, 1200 for max you'll automatically have a mask where evything closer than 500 is 0, everything between 500 and 1200 interpolates between 0 and 1 and everything above 1200 is 1. to make it have the desired range I had already tried everything I thought about (multiply by small numbers, add the min expected distance) and the picture above was the best Oct 6, 2016 · Hi!

Person A: “Using a Scene Capture 2D, I can not manage to make ONLY one actor visible and everything else ALPHA, I want the texture to be 100% transparent except the actor. It’s useful as a visualization but it’s not helpful as a depth map. When I plug it directly in to the output to see what’s going on, it seems to just be outputting a uniform white (output value 1?) for the entire screen regardless of depth. This is not the desired result. In the pixel shader I’ve tried: returning a struct struct PS_OUTPUT { float4 Color Similar to what happens with real-world cameras, Depth of Field (DOF) applies a blur to a scene based on the distance in front of, or behind, a focal point.
