Converting Hdri Spherical Maps Into Hdri Cubemaps

[rgkovach]

anyone have any pointers on converting HDRI spherical skymaps into HDRI cubemaps?

the only solution i can come up with is to:

1. export a separate LDR image for each exposure
2. map each image onto a Sphere, and render out a cube map for each exposure level
3. reassemble the 6 images in photoshop for each exposure level
4. recomplile them all again into a single HDR file

is there an easier way???

I don't have it in front of me but I think HDRshop can do the trick ... Have a look at www.hdrshop.com, the version 1 of the software can be downloaded for free, thanks to Mister Debevec ...
