Subject: My Light Won't Shine Through Window?

Hi All,

I have a wall with a window in it. There are no window panes, just geometry with real gaps in it.

I place a light outside the wall and add a plane on the other side to catch the light.

I get nothing, just black for my geometry and background color for my hole.

I am running the latest version (what is is 2.43a?)

I am using the Internal Renderer. I have tried all kinds of lamp types, all kinds of intensities and distances.

It shouldn't be this hard...

Hi Enivob :)

Enable the Trasha (transparent shadows) button, found in the shaders tab, for any material that will recieve transparent shadows from light after passing through glass.  I am thinking that maybe it renders faster with it off and is why it is not on by default.

Thanks for the reply.

But I have tons of textures, it is an architectural piece.

I have pretty much given up on having light come through a window.

Is this what you're trying to do?  You shouldn't be having any problems getting the light to go around real geometry, if you don't have a window pane in there.

Yeah,

 

Thats what I though too.

Try putting the whole thing on a box now. And then put the light outside the window. It should work, but for some reason it was not working. I have moved on from that project since, however.

 

Thanks for the reply, it is good to know it can be done.

PS:What type of light are you using?

It's just the default light, default materials there, I didn't change a thing.

What do you mean by "putting the whole thing on a box"?  Do you mean you're putting the entire scene inside a box?  I'm really curious what's going wrong, it seems so strange that there should be a problem.
