...they don't let the light pass thru nor generate shadows.

check these 2 screenies:

A transparent texture of a window (I know, wrong uvs) with some frames that I'd expect to cast shadows on the floor, but the light doesn't even come into the room:

Same room without the window brushes; check how the directional light placed outside bounces on the floor:

any ideas?

ps. Oh yes, this is my 1st post as a pro user! Wink

Oh yes! and then when I load my level into Irrlicht transparency is gone:

I saw a similar post by MikeR here, so I guess it's a problem with TGA transparency in Irrlicht. Wink

Hi afecelis, and welcome as PRO user! Very Happy

Did you set the Blendmode of the texture to Alphablend? That should make a difference.

Thanks Jeroen!

yup I did all that:
1. material editor:

I wish PJ was here to answer this question because he knows more about the subject than I do. In the mean time, can you send that texture to my emailaddress (in my profile)? Might be useful for testing purposes! Smile

Houston, file has been sent! Very Happy

I haven't received the texture from Jeroen yet, so I am just going to spill some theory here Smile

The lightcolor filtering when moving through the material is calculated (rather arbitrarely) as

mmmmmmmhhhh....interesting........ and in English? hehehehe Wink

Thanks PJ for the reply; as you can see I'm not much of a technical person, ehehehhe. I don't have your email but I uploaded the tga texture here:
http://www.danielpatton.com/afecelis/Deled/window01.tga

It's just the one that comes with TGATOOL form ths Cshop tools.

Thanks for the interest!
Very Happy

A thanks a bunch! I will see if I can figure out what is happening!

well the good news already started!

Salvatore's new code for Irrlicht corrects TGA file transparency:

now all I'm missing is light coming in thru those windows Wink

PJ,
Don't you have to set the sample rate super high to achieve this effect? I seem to remember somewhere that you talked about it, just can't remember where.

more great stuff!

I just imported a 3ds model into deled (which loaded perfectly with textures and everything), lightmapped and loaded back into Irrlicht and it looks great!

advantages:
1. Now I don't have to add my decoration meshes and props (3ds files) via coding in Irrlicht but directly in my level.
2. They will be included in my collision code since the dmf file is a whole one.
3. They are lightmapped!!!

love it love it love it!
Very Happy

more stuff:
I can then model additional stuff in 3dsmax and bring it back into my level:

note: the columns are merely experiments with extruded splines in 3dsmax. Better said; this whole level is an experiment to see what Deled can and cannot do. So far, everything is a "can", hhehehe Wink

the only missing thing is light passing thru transparent tga's.
