That is not initially easy! I have imported a Poser file into DAZ Studio and did two 3072x3072 Render-To-Disk renders. The OpenGL rendered in almost a FLASH!. The non-OpenGL took several minutes, but looked quite different from the original Poser image- mainly like the lighting was set too high. An interesting image, but NOT the same. Bottom line- in this ALPHA stage, it is hard to compare Apples to Apples. There doesn't appear to be an immediate translation of identical light levels- so you can't make exact comparisons. This is an ALPHA release- meaning NOT EVEN BETA! I'm amazed that my Poser files even load an look similiar!
