Kray version 1.611 is out.
Kray has beed updated. Improvements include:
Multiplier of secondary bounces added
You can find it under Photons tab "Multiplier". It will boost the secondary bounces so you can use if for example you don't want your sun to get blown out.
Faster blurred reflections/refractions
You can now control how blurred reflections are rendered. There is a setting in Misc tab: Blurring accuracy limit. This means that if the reflection blurring on a surface has a this value or higher, then Kray will only use irradiance map in to compute reflection which is much faster then doing the FG reflections. You can set this to 20% and all your surfaces that have blurring set to 20% or more will get rendered much faster.
Lightmap walkthrough animation
There is no switch for that. Just set up your animation and fire up kray.... it should work just fine.
