I recreated the sphere material in blueprint using the volume vector locations as the absolute world position, but that isn’t quite working. Getting some weird spoon shaped formation.
Apart from the opacity mask, the math is set up exactly the same way(unless I read some of the material stuff incorrectly). Basically everything that feeds into World Position Offset.
So, if the math offsets an individual pixel into a sphere shape, then it should also do the same for an actor. Except it isn’t.
I attached a sample of the material converted into blueprint. I will keep working on it.
