arkit - Scenekit - add red tint to camera -


is possible add red tint given camera in scenekit? accomplish without (what consider be) hacky solution of trying shove red object < 1 opacity in front of camera. solution haven't had great success in scenekit showing object right in front of camera.

also, ideally, fade red tint in , out using scnaction or other way.

finally, perfect solution work in arkit, , give red tint whole world around you. have more red scenekit light.

scncamera's colorgrading property can (that efficient option). using scntechnique apply custom post process work requires additional pass. both options faster blended node in front of camera, or red-ish spritekit overlay or uiview on top of scnview.
