Katana Integration Support

I decided to take a very brief detour in my plans and quickly prototype integrating Imagine into Katana 1.5 as a Render plugin…

Currently only very basic support for Disk Renders of subd and poly geometry, arbitrary transforms, default materials and physical sky light…

But as a back-burner project I’ll possibly keep chipping away at it - would in theory allow slightly saner comparisons with production renderers…
