Hi -

I'm having trouble with HDRIs and have formed some questions that I hope some light (no pun intended) can be cast on.

Untransparented Poser Eyebrows/Lashes.  It seems that some HDRI maps I use produce transparented brows and lashes while others with the same rendering settings (ie. all transparency light throughs checked) do not.  Is that true?  Can the properties of the individual HDRI maps make or break that?

One render I did produced an overall blue tint to the model - all transparencies worked in that render.  What's up with that?

Are there steadfast rules to rendering with HDRI?  SkyLight only?  Indirect only?  Either or both ok? Also, are high intensities recommended?  Should one leave the intensity setting of the HDRI map area at 100% and only make higher intensities at the SkyLight/Indirect Light levels?

I think I read once that adding a bulb light to the scene can fix the no transparency on the brows and lashes no matter what - is that true?

Is there a tute or difinitive list somewhere that addresses everything HDRI (for carrara 5 pro)?

Thanks if anyone can help with any of those - I've spent a lot of time experimenting without getting difinitive results so I'm finally asking.  Thanks.

David
