I noticed that not all intrinsic material HLSL functions have a node. It would be nice to have them all. For example, for an effect I’m making, I would really like to know the angle between a the UV coordinates of the current pixels, and some UV coordinate that is the center of my effect. In HLSL I would use arctan2 for it (atan2), but it seems there is no node for this function. Also other are missing like acos, and asin etc.
Hi BramV,
Thank you for your request. I have entered a feature request, UE-21999, to be considered by the development staff.
