Can the Spherical mode of the ImageProjection node be used to project equirectangular spherical images, like you might get from a Nodal Ninja? If so what’s the trick?
This is what I get with a test sphere and spherical projector at the origin. Note that I’ve decreased the horizontal field of view from 360 so it’s easier to see that all of the image edges are converging at the pole. Back face culling is also off so we are looking at the outside of the sphere.
This is what I was expecting to get using a lat-long equirectangular image with the top and bottom rows converging at their respective poles.
As I was writing this I just realized that maybe even though the docs say lat-long image perhaps the Spherical projector is actually expecting a environment map, i.e. mirror ball image? I’ll have to try reprojecting and see if that works better.
