Wouldn't it be cool if we could use Light Cache for secondary GI with RT in Active Shade mode the same way we can use Light Cache for secondary GI with Vray Adv 3.5 IPR?
In the help pages of RT it says that Light Cache is not available for RT in Active Shade mode because "re-calculating it every time the camera changes its position in Active Shade doesn't make much sense". However, I've found that when using IPR in the beta of Vray 3.5 it's perfectly fine to use Light Cache as a secondary engine for real-time rendering as long as you set it to something low like 500-200 subdivs. I can still navigate around the scene and get decently fast Light Cache calculations with this settings, especially if I'm using region render. I would guess that most users can use the same approach with RT? Besides, 90% of the time people using RT in Active Shade do region renders anyway when adjusting their materials/lights so updating light cache shouldn't be such an issue.
Maybe my reasoning is not really correct since I'm not a developer but my experience with IPR in Vray Adv 3.5 tells me that it shouldn't be impossible and impractical to have Light Cache in RT Active Shade mode. Any thoughts?
