Title: Light does not pass through transparent objects
Post by: Samukun on January 11, 2010, 06:47:38 pm

I'm having some problems with my current project. What I want is something like this:

But as you can see from this, as soon as I put in the windows, the light fails to pass through it.

The window's transparency is set to 0.1. What am I doing wrong here?  ???

You cant, simple as that. The only work around really is to do two renders, and photoshop the windows in.

Hopefully the next release of anim8or will have a better ray tracer that allows light to pass through transparent objects, or at least tell them not to cast shadows.

that is 2 bad.

but the good thing is u can easily make the windows and the outside view easily. ( if you dont have photoshop. get GIMP, its free and pretty damn close to photoshop)

I would advise simply leaving the windows as they are in the original.  Since a window pane is so transparent, you can't tell whether there's a pane or not anyways, so people assume there is a pane anyways.  I say leave it as it is when the shadows work.  If you want some reflections you can add them in photoshop or something afterwards.

hi Samukun, ;)
my suggestions is..
try maker the windows has a OBJECT SEPARATE;
- select and "detach" the windows and maker  has other object
- in "scene mode" position your windows WITHOUT CASTS/RECEVEID SHADOWs.

i hope then help your..
sorry my english!

You cant do that with ART though.  All objects must cast shadows.

heres what you can do. You can make the tanparent glass seperate from the window fram. Only make the frame cast shadow and make the glass not.
