Spotlight Not Illuminating Inside Building

Question

I need to render this scene where the sunlight is entering though the windows and making shadows, I added a spotlight but it seems that the light is only working outside, I have no idea why. My windows have no glass yet.

Of note, I am using 2.79 because of my current hardware.

The weird circle you see in the windows is that i accidentaly duplicated the glass, i deleted the duplicated faces and correct the normals and now everything is looking goood

the problem is your window material and the fact that it isnt transparent. Are you using alpha blend for the window material? I would also suggest rendering at those specific angles for your screenshots instead of just screenshotting a graining un-rendered preview. — object, Apr 14 '21 at 02:55
you should include screenshots of your settings or link your blend file so we can check it out — Chris, Apr 14 '21 at 05:29
it may have to do with light through glass? maybe the solution is to create a emissive plane or an area light at the windows position? — moonboots, Apr 14 '21 at 07:30
@object Hi, the windows has no material and no glass either. i was following a tutorial and the guy was doing it on blender 2.9 , he simple added a wall with holes and then the light, volume etc... aand the light was perfect and casting all the shadows of the windows's frame. i will try adding the glass mesh to the windows to see — wnr, Apr 14 '21 at 11:09
@Chris one thing i found out so far is that selecting the "non color data" inside the image texture node enlightens the wall when i choose sunlight — wnr, Apr 14 '21 at 11:57
It looks like perhaps you've got a default world light on the exterior, but then there is some faint light coming through the windows - presumably from your spot lamp. Have you tried to increased the power (watts) on your spot lamp? Or perhaps try a sun lamp... as other commenters have said some screenshots of your light settings, setup or blend file would go a long way here. Hope you work it out. — Aubrey, Apr 14 '21 at 12:58
@Chris i added to the post but i dont know how to pack the texture and everything into the file — wnr, Apr 14 '21 at 13:06
@Aubrey hello, i added new sscreenshot and blendfiles and i am sorry for not doing this before — wnr, Apr 14 '21 at 13:07
@wnr: your link does not work. To include all into blend file use file -> external data -> pack all into blend file, then save, then use this link: https://blend-exchange.giantcowfilms.com/ and follow instructions — Chris, Apr 14 '21 at 13:16
@Chris Hi Chris it is working now, i packed eveything. thank you for the info! — wnr, Apr 14 '21 at 13:29
@Chris Thank you so very much! it looks so beautiful now ! :) but i jjust cant find the (blend mode and shadow mode) what section is it located? i am on 2.79 version, — wnr, Apr 14 '21 at 14:04
i have no idea. my first blender version was 2.92 when i started with blender :( — Chris, Apr 14 '21 at 14:06
i asked a new question for that https://blender.stackexchange.com/questions/219533/how-can-i-change-the-blend-mode-to-alpha-in-2-79 — Chris, Apr 14 '21 at 14:12

@Chris yes i am reading these now. When i saw the blend mode and shadow mode i remembered seen it somewhere before, as i am trying to render in cycles i was looking for it there but it couldnt be , it makes sense that it is in game engine and internal render mode on 2.79 but i had no idea as i couldnt remember — wnr, Apr 14 '21 at 14:45
