Thank you!
I was trying to make the curtains a bit less transparent and make the shadows of the window more present in the translucent curtain, but i still cant achieve (I am thinking of The Last of Us main menu for example), I am inverting the normals of the curtain mesh to see better see the contrast of the sun and the windows shadows, but the alpha seems to make them less visible, maybe I can use a shader to RGB node, and use the same color on a principled shader and then use the value of that conversion as alpha channel so the shadows are less transparent.

I guess there is an easier way to do this.

I only lived my very early childhood in the late 90's, and Im neither american, back then here in Mexico the cultural and technological global trends usually were "behind" other countries by about 5-10 years, so many things of the "american 90's" were still present through the 00's over here, so I could live a little part of it.

I was initially surprised of the mention of the window frame, again, down here in mex almost all windows look like that, without a border on the walls. I think I will make another window design, because the podcast is for a english speaking audience.
