Projection 360 HDR onto geometry?

#1

Hi,

I am struggling to project a 360 hdr onto simple primitives in maya…

Found lots of tutorials for projection normal pictures onto geo but no good/ complete ones for projection 360 panos to primitives…

My HDR is of the inside of a warehouse- I want to project just one wall because I moved my object (a car) closer to the wall and my HDR was shot in the center of the warehouse. So I just want to move this ‘wall’ closer by projecting the hdr onto it, thinking I could get better reflections

I searched here and found this but it doesn’t make total sense to me http://forums.cgsociety.org/showthread.php?f=87&t=390324&highlight=hdr+projection

Here is my result, stretched crap on my wall instead of a nice clean brick wall that I was hoping/ am aiming for

the best way to do this is HDR set reconstruction, do a tutorial search on that , is quite easy.

Lol are you kidding me… if it’s so easy why didn’t you just tell me? First thing I mentioned in my post was i couldn’t find any good tutorials for exactly this -_-

Please, either point me towards a tutorial about this specifically or let me know what I’m missing :slight_smile:

No matter what I search for on youtube vimeo google chaosgroupforums cgsociety forums I can’t find whatever it is I’m missing. There are many tutorials for general camera projections but not for spherical HDRs to primitives…

I would texture it in mudbox or mari…
Thats the fastes and cleanest way…

the distance between the 3dtexture manipulator and your geometry is important, you will have more or less stretch.
Once you have exactly the projection you want, group your geometry and your 3dtexture manipulator to move them together to place it where you want.

update- turned out I had it hooked up correctly, but it only shows up in render. don’t know why I expected to see it in the viewport! doh
