What I’m trying to achieve is to have this position reveal the terrain in a spherical manner using the alpha. It is based on “PlayerPos” This works on editor when in object space. However, the position is incorrect when translated to device.
I’ve tried to use the Polyspatial Volume to World, however, that seems to only be for world space.
Is there anything else I am missing to get it to translate right in simulator/device?
Right; the PolySpatial Volume to World node can convert from the “world” space output from the Position node to actual Unity world space. Unfortunately, the reverse transformation isn’t possible at the moment, partly because Apple doesn’t provide shaders with matrices that can map the visionOS world space to the local space of the scene root. If you’re interested in that functionality, I would suggest that you provide feedback to Apple.
