CoronaDistance and CoronaAO exclude/include objects and lag

[Image Complete]

Hello there,

I am facing an annoying issue regarding CoronaDistance and CoronaAO when I exclude or include objects.
It looks like both of these features bring lag on the viewport and in general during I work on the scene.
It is like 3ds Max runs calculation real-time when I move, rotate or isolate an object (or a group of objects) which happens to be included or excluded for a material that has CoronaDistance or CoronaAO. For example, when I have a floor which has a "dirt" effect but with specific objects close to it and I try to to do something with these objects I got instant lag.

More objects bring worse lag. It feels like it shouldn't be like that because I don't do IR to see that "dirt" while I move objects.

Is it something I only face?

Edit: I work with Corona 6 Hotfix 2 at the moment. I didn't find yet a gap between projects to update the engine

Cheers!

Can you please clarify if any of the distance objects have dense polygonal geometry?

Hello!

Yes they do. Most of the times are props or furniture with high count of polygons

Thank you for clarifying, we have this logged and hopefully some further improvements will be introduced in the future. For the moment it might be prudent to use your distance interactions based on a low-poly gizmo object that is linked to each prop respectively, this should significantly improve performance.

Enjoying the post, have som way to aply corona distance to multiple material at same time, example: im use this to cut ou the grass in alignment of the pavement floor but in models of grass this have tons of materials to insert the CoronaDistance in Opacity MAP.
