Reflection blur amount

[gristle]

Hi all, first post here.
I'm having some issues with reflection blur. There seems to be a huge difference in the amount of blur between Lightwave/FPrime and Kray. For example, 20% ref blur in LW/Fprime looks like 200%+ in Kray.

Should I be using much smaller blur amounts, or is there a ratio to use as a guide?
I had a search but could not find any information.

Cheers!

This is because LW changed blur amount behaviour in version 9.3.1. Fprime still renders blur the old way but Kray renders the new way. In LW renderer you can control between old and new by switching "Compatibility" setting under "Advanced tab" in Surface Editor. The difference is about 3x stronger blur in new version.

Hi Jure,

Thanks for the reply.
Normally use FPrime so never heard of this before.
