Difference between IPR and Prpduction

[Romankey]

I have a big difference between ipr and production render. Render on CPU.

I try BF + BF, BF + LC for production and try to bucket and progressive, no difference, the result is the same. Overexposure on production.

How to be?

On link It says that the Max does not have this problem. That in Max IPR works correctly. Because Maya have no light cache in IPR.

Hmm, maybe i finde whats happen, but i dont iderstand how to fix it and how it can be.

When begining production render, my sky portal work like a v-ray lights.

When no portals, i have no difference between ipr and production.

What the strange things? How to fix? (V-ray 5, hotfix2)

Consider giving up on using portals for your next project and just flag the Adaptive Domelight.
