In the post process material blueprint, what’s the difference between Scene Depth node and SceneTexture:SceneDepth node? or are they actually the same thing?
SceneTexture:SceneDepth outputs a color value consisting of 4 components, as described in documents, and which specific channel value can be used as a depth value, or all of 4 can be used?
What I want to do is to replace the alpha channel of a capture2d’s rendering result texture with depth value. I’m not sure how to do it correctly. My post process material graph looks like below.
