How to set collision for light radius in Niagara system?

Hi! I was able to figure out what I wanted to achieve from the Niagara system in terms of good quality versus optimization. But in the process I encountered some problems…

Unfortunately, the light renderer doesn’t work like point lights (as expected). However, it works quite well for me using the cascade light converter properties. And in general, I am more than satisfied with the result, except for one BUT.

The radius of light does not see boundaries, which is why it shines even beyond other objects.

Please tell me how can I solve this problem? And will it be cheap to use such lighting in many areas of the game? I want to achieve a natural glow from the fire.
