VRayHairNextMtl bounces don't work with IPR

[dgruwier]

Not sure if this is a bug or just just a technical quirk of how the IPR works, but the Bounces parameter of the Next hair material is stuck at the default value in the IPR.
This should be easily reproducible by creating a default VRayHairNextMtl, setting the bounces to 1 and rendering once with production, then IPR.

Thanks for the report. This seems like a bug since it does not happen in V-Ray for 3ds max using the same scenario. I'll forward the information (Bug-tracking system id: VMAYA-9036) to our developers for further analysis.

Thanks! It's not a critical bug for my part, just a curiosity I noticed.
