When you do the first render it comes out overly bright and is fine in the second render

how get around this if you set up to render multi. sceens over night ?

SR3?

SR3, yes

I don't remember this bug, but what you described tickled enough of my memory to cause me to think I ran into it.

Does this 1st-render problem happen after loading a new scene or just after starting Poser?

How are you currently doing multiple unattended renders? 

If it's a startup problem only, perhaps a script could be used to load and render multiple scenes without starting Poser over and over. But I suspect that's already what you are doing.

typically I'll work on a project once Iam happy with it I save it close poser and re-start it for the render, because you know memory problems and such it gets buggy and heavy so a fresh re-start less problems. most time's I have 1 IBL. on the re-start and it comes out washed out.  what I do is make a tiny area render and then the full render no big deal.  Because the sceens are bigger and more complicated they take longer to render so why not get a script to render 2 or 3  at night but no point if I use Ibl

tested a sceen rendered with default poser lights then loaded a Ibl light set from libary

and its needs 2 renders, technically I guess it needs to  calculate Radiosity ?

does this happen in poser 8 or pro ?
