I would like to understand the meaning of the wrapping methods.
I didn' t find the answer in the manual, neither on the forum.
I tested the 6 methods with the same image and I got some ideas but too vague and a lack of depth understanding.
So what are they doing ? Spherical, Hemispherical, Angular probe, Center, Tile and Fit.
Thanks for your answer.
Spherical wraps the whole image around the scene as if it were painted on the inside of a large sphere surrounding your scene.
Hemispherical only maps the image to half of a sphere that is a dome over the top of the horizon line around your scene
Angular Probe uses the projection used in any HDR that says "probe" in the name of it. otherwise, if you load a probe into a spherical projection, then it will have a black hole in the top or bottom. Angular Probes usually have a thumbnail that is a circle of the image with the 4 corners black.
Center Tile and Fit... I've not played with in Thea, but if they are like in Kerkythea, do not use them, they do not contribute to lighting of the scene, nor to reflections, they are only for putting a 'dumb' background picture behind your object... they are what I would consider 'legacy' items there from ages back.
