Hi mightyenigma.
I have used this many times in world widgets inside VR applications. There isn’t any noticeable pixelation from our experience. You need to make sure anti-aliasing is configured right for animation 3D widgets and it works like a charm.
This only thing about this solution is that it can be a sod to get to animate from a particular point, i.e. animate out of the centre rather than the top left, however, if you’re confident with widgets, it just requires a little restructuring.
If you’re happy with this as a solution, please vote and mark it as an answer for others to find, otherwise, let me know any other questions you have.
Good luck
