Corona render - Light sources turned black on render

[wideanglelenc]

Hi guys,

first of all I have to say that I am a begginer in 3ds Max and Corona, i started yesterday, so please, be patient with me :D.

I would like to use  3ds max with Corona for Virtual staging (adding 3d furniture into photo of empty property), so I started with few tutorials...
I did perspective match, built the room, but now I have a problem with my render: I put 2 lights there. They do emmit the light, but on render, they are black.
Any advice?
I need to see the window from the original photo and make it emmit light.

Btw if you can reccomand any good tutorials related to topic of virtual staging (but also for basics of 3ds Max and Corona), I would really appreciate your suggestions! :-)

Thank you very much!
Tadeáš

Okay, probably I just solved this. I used Cap holes modificatorin in windows and poof, black is gone. :D
Thanks anyway. :-)
