I did some test with the new user_ibl shaders and I found that the user_ibl can only takz inputs of type file. it's not a pribleme if we want to use a hdr file, but it's not possible to use a simple ramp or constant color. Exept if we bake it into a file.
So is there a way to use color inputs instead of file inputs ? is that a hard limitation in the fonctionnement of the user_ibl ?
I also noticed that the environment is fliped and rotated for 180 degres when compared to the native ibl when plugin the same hdr in an environment lookup.
I know there was the same flip issue with the old ibl node. so which is the good one now ? rotating the ibl is easy, but fliping it means doing it in another programme. the user_ibl seems to ignore the place2dTexture when using a maya file instead of a mentalRay file.
edit: could a moderator correct the error in the title ? (the "c" in user_ibl_env), I can't change it. thanks !
