As I explained earlier, the goal is to map a texture so it’s planar from a point of view, but independent of the camera, to produce renderings like that:
I checked how it behaves in the new Beta and it’s as buggy as ever.
Using the same file as before, the results have not improved (still using spherical mapping with “Ray” projection). The Rendered style viewport is almost correct but Raytraced and Render are weird.
Can I expect some improvements soon?
