Raytrace engine setup before rendering takes for ever

[lucano_deskovic]

Hi, I just moved to v7, and in my current project, when I render, before every render, there's a Raytrace Engine Calculation status box that takes for ever to calculate.
In v6, such scenes would already have the rendered few passes. Whats wrong with this. How do I fix it.
I tried pinpointing bad materials, and scene conversion, but no help.

Not sure what you mean by "Raytrace Engine Calculation"; can you clarify? Does rendering the same scene in V-Ray 6 finish the calculation faster? If yes, send the scene, so we can troubleshoot.

EDIT: Are you rendering with GPU? Maybe you mean RT engine?

Ive reverted back to 6.2 so it will take some time untill i can do that
