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.

enter image description here

I added a glass material to my windows to see if ti would help with the light but this weird circle came up!


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

    $\begingroup$ 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. $\endgroup$

  • $\begingroup$ you should include screenshots of your settings or link your blend file so we can check it out $\endgroup$

  • $\begingroup$ 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? $\endgroup$

  • $\begingroup$ @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 $\endgroup$

  • $\begingroup$ @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 $\endgroup$
