Quote - Every time? No matter what the content or settings? I had a user yesterday tell me that IDL takes 10 hours on her machine. Turns out she had the settings at completely ridiculous values, now it renders in 12 minutes.

Yes every time. I tried different settings. When I render the poser screen is black with tiny red dots. I'm assuming that when poser calculates the IDL. Depending on the scene it takes cca 30 minutes but when it actually starts the real render FFrender stops working.
