A Salesforce ticket reports that entering the above code into a custom node in a Material Function causes a crash. I was able to repro his crash reliably.
This is a regression. Working as expected on 4.25.4 CL 14469661.
return CalcSceneDepth(ScreenAlignedPosition(GetScreenPosition(Parameters)));
Expected Result: Material changes are applied. No any errors and SCENE_TEXTURES_DISABLED_SCENE_DEPTH_VALUE value from function result
Actual Result: Crash.
