I’m currently working with FumeFX on some heavy scenes to render, and also using Krakatoa to create some slightly different looks . I wasn’t getting what I was looking for so I did some looking around and found this page:
We are currently beta testing Krakatoa 1.5.0 and that page slipped out too early
If you are a current license holder of Krakatoa 1.1.x and your support contract is paid for this year, you can join the Beta testing.
In that case, please send your details (license holder name / company name, license server name and MAC address) to krakatoa-support AT franticfilms DOT com and we will give you access to the hidden area of the support forum.
