Interactive rendering and Render dont match issue

[marco_zanella]

Hello,
I am having a problem in the VFB with interactive rendering and render, please see image attached.
I am using just rectangle light and all is on default settings.
What am I to do to fix it?
Thank you

Hi marco_zanella ,
the reason why you have different results between Interactive rendering and Production rendering is because Interactive rendering doesn't work when you have Light cache selected as a GI engine (this is a limitation in all V-Ray integrations excluding V-Ray for 3Ds Max). So every time when you start Interactive and you have the GI engine set to Light Cache V-Ray automatically sets the GI engine to Brute Force internally. If you want to have similar renderings between Production and interactive please set the GI engine to Brute Force and try again. We print a warning for this and many other limitations, but we don't want to pop up the console window for every warning but only for errors.

Let me know if you're still getting different results after my suggestion, so we can look for the issue somewhere else.

Hello Shaio,
thank you so much for your kind replay.
All is fine now, only thing is the increase of render time....basically if i want to use interactive render i can only do with brute force as secondary bounces
we will have in the future the possibility to use Light cache as 3d max?
Kind regards
