Transparent Window - Mirror Bug?

Marotzke · Post by **Marotzke** » Sun Nov 19, 2006 10:43 am

Hello!

After working through the "Blender 2.4 / Indigo 0.5 Tutorial / Manual - version 0.12" a few times now,
i got stuck at some peculiar problem. But see for yourselves:

The window seems to reflect the ground, but this should be impossible -
I didn't activate any raymirroring in Blender before exporting to XML.

That's what I use:
Blender 3D 2.42a -> XML Script -> Indigo 0.6 Test 1

This file contains the blendfile (packed) and the xml file with the texture:
http://home.arcor.de/gottofdarkness/Bil ... cene10.rar

XML file only:
http://home.arcor.de/gottofdarkness/Bil ... sunsky.xml

I played with several settings in export and materials (all three available); for the ground mesh, the windows
and the world texture (which is or should be just white). But i never got rid of this strange mirror-bug?-thing.

Would be nice if anybody could help me with this, thanks

Are you using objects for the windows? If so, indigo automatically gives transparent objects reflection, as in reality.

Yes, I use a 4-vertice plane for the windows... to give them some IOR in the materials.
And why shouldn't I? Real windows are from real glass (so I model them), and mine don't reflect that unusual way.

Hmm.. do you think I should remove them?
But somehow I can't think of that...

I would use a thin cube as a window if I where you, makes it more "real"

Hello!

Now that I used a thin cube; I must sadly admit - it didn't work the way I wanted to:

(Windows + Sunsky)

More pictures:

Btw.: The bad ground comse from the bumpmap, I think. But that's not the problem.

Thanks for help in advance

Try inverting the normals on your dodgy window.

Ehmm...

...it worked fine

Thanks!
The normals had to point inside... hm.
I'll keep that normal-problem in mind.

Thanks twice... now my life has a meaning again

Edit
@IanC
Thx for the tip; I'll remember that too

Always make sure it's a cube though, because if the window doesn't have thickness, indigo will assume it's glass from there out.
