Quote - haven't noticed any recent problems, but most common complaint: GC caused scenes set up using poser 4, 5, 6  techniques to appear washed out.  they used sets with dozens of lights to fake GI.  they may still be doing that now.

I bought an environment set by a very well respected set maker recently that came with such a light set. Numerous infinite lights, named "ambient".

Likewise, a material set, from another vendor, specialising in textures, which seems to have all the ambient channels, in each shader, set to ambient = 1.0.

As far as I understand it, neither of these approaches will work well with GC, or indeed IDL... and are old school Poser workarounds, from the pre-GC, pre-IDL days??

These were from two of the biggest vendors in their respective marketplace categories. I'm not saying they didn't know what they were doing. I guess they were maybe just targeting the majority?

So, perhaps no wonder most Poser users are still struggling with this... it seems to me that perhaps the majority of marketplace products are quite likely still not properly compatible out the box??
