Thanks a lot bepeg4d

I'll try that out. My only issue with hdrs/exrs is y that they render too dark and sarurated, so I end up using jpg versions of them in Octane. So I'll mix the 2 as you suggest, a sunsky to get hard shadows and a jpg applied as IBL to get nice window reflections.
I'll post my progress soon
Regards,
Alvaro
