Noise caused by the Quad light implementation

[isolog]

I found this problem in C4D at first, see this post:viewtopic.php?f=9&t=80923&p=419965#p419943

Anyway it looks like a weakness on Light rays which are blocked by self at zero angle between faces. You may export ORBX and post in standalone topic

I then exported the scenes to standalone for testing.
And found that the C4D quad light in standalone is a mesh with a emission material and still has noise (I simplified the nodegraph to see).

light from C4D

light from standalone

So I'm posting this in the C4D forum.
I would like to know why C4D quadlight is implemented differently than standalone, and if this noise problem can be solved.

Here is the scenes file.

Perhaps a little presumptuous, please forgive me.

Looks like "use primitives" parameter is internally resetted in plugin side. It's working well if we correct the problem.
