RT and Lightcache - save to disk

[QuakeMarine1]

hi
I run 3dsmax - RT on CPU - simple scene
I set LC flythough for primary and secondary - enable "dont render final image" and render

I see no LC prepass and RT start render immiently until my max samples are done
no LC is written to disk and "dont render final image" seems to be ignored

even LC sampls 65000 do not show any difference

bug or feature ?!

Do you have Vray RT set as the Production Renderer?

Do you have the same issue with production render?
Which version of V-Ray do you use?

Light cache is supported in RT when render with RT GPU mode only.

indeed - with Gpu I see a LC prepass - but the dont render final image is ignored
looks like RT need to be polished a lot more

I wonder why Cpu not do a LC prepass - do it use LC at all ?

running nighlty build 3.sept.

Yes, my tests confirmed that as well. Don't render final image is not taken into account with RT / GPU production rendering and will see if this can be fixed. But how do you want to use this option with V-Ray RT ? What is the workflow you want to achieve?

It is done only for the GPU engine for now. I have to check if LC is planned to be supported by the RT CPU engine in the future.
