Here’s a relatively simple script thats already saved me many headaches.
Basic Gist: as its set up It will create a directory called ‘Calcs’ under the directory where your maxfile is at, and will switch your filenames for vray irradiance maps and light cache back and forth between saving to, and loading from file in that directory, it will save the calcs as “maxfilename_cameraname.vrlmap/vrmap’
its set to use a UNC directory where possible, and to use irradiance map and light cache. Theres not much error checking in it, its currently set up to work for us internally, If anyone has issues with it, you can contact me. I think its helpful, but not ‘solid?’ enough to drop up onto scriptspot as yet.
