Hi there,
I’m trying to load an hdr image into ZBrush for lighting purposes, but every time I try to load the .hdr-file, ZBrush crashes on me. When I save it as psd, it’s just plain gray in the preview (Mac OSX). In ZBrush it’s the same with a lot of artifacts.
Any suggestions? should I just convert it down to jpg?
thanks in advance!
I have the same problem!
Mac os x snow leopard (latest version pre lion) ZBrush v 4R2. Loading in any HDR file (that works in any other 3d app normally) crashes zbrush immediately. I’ve tried loading it into light-background sub palette asper the new manual and crash… I’ve also tried to load it into lightcap image import as well and I think texture import. All of them crash immediately…
Submitted a ticked to support and when I hear back any thing that will help I’ll post here.
Thanks
Ben
I started a thread last week about this crash but more reports to support the better.

I have the same problem with HDRI’s crashing ZBrush (Mac OSX 10.6.8)
Confirmed
OSX 10.6.8
No hdri for OSX users then.
balls. and what about Mac OSX Lion?
I also noticed that environment pictures in zbrush4r2 folder are just 8bit jpg images…
Or
you may try to save as psd in Ps.
This time no crashing but after waiting for~1 min you have this beauty.
yeah, got the same result with PSDs 
the only thing that kind of worked for me was copying the hdr within photoshop and pasting it into a new picture. that way, it will look the same, but you can save it as JPG and import it safely into ZBrush…
still, not the solution I had hoped for
I was just going to ask the same thing… I know Lion isn’t supported by Autodesk (Maya 2012) but with Z4R2 (DynaMesh, new lighting and rendering) I no longer need Maya lol… 
- Z4R2 is pretty seriously fantastic. DynaMesh literally blows my mind. no more lame basemesh topology NONSENSE. I have wasted far too much time welding verts and re-projecting… THANK YOU for DynaMesh you have no idea…
