I just wanted to ask because I could never really work with HDRIs inside Rhino with V-Ray. For some reason I never end up getting the result I am looking for, but most importantly, it is always a pain to work with them.
Mainly because they take too long to load and display changes. I have a pretty powerful pc and still it is not like I see with other 3d software where you can rotate hdris live, and get a preview instantly. Blender, Cinema, w/e.
Also, I find the controls are lacking customization. I work a lot with horizon images. Most of the HDRIs come with a ground, so that is a problem. Even when using ‘hemisphere mode’ some things of the ground still come up in my background sky (buildings, mountains, etc). I just need to lower the texture a little bit in the z axis, but there is no way to do that. All I have is an awkward Rotate V, which tilts the whole picture diagonally. Not sure why someone would use that… I often feel super constrained because of this, and can’t concentrate only on the light because I need to try different minimal rotation values just to hide portions of the HDRI I don’t want to show. Like, Rotate V two degrees, then Rotate H some more to hide this behind that geometry… it just doesn’t feel right. And the fact that v ray is so slow at updating changes, having to make a ton of small changes (0.1 degree) makes it all so much worse.
Does everybody experience this and just accepts its the way it is or I am missing something?
PS, I have two small questions:
With a 8k HDRI I need to input 7680 value into Tex. Resolution right?
Is it common to use Rhino Sun + HDRI or should I use them separately? Do I need to tick some setting to combine both?
