Hi
if i turn stencilbuffer shadows on, my transparent parts switch to solid colors
(may be they are very dark, not realy solid...)
The shadows and lightning seems to be ok...
Whould be nice to have some hints about this problem...
thanks
max

I noticed that too, but only with Direct3D8 and Direct3D9.
I changed the material flag EMF_BLEND_OPERATION to true and it appears to fix it.
I am a newb with Irrlicht, so there may be some side effects on turning on this flag which I do not know.

Defaults for blend operations changed recently in svn. I also run into this one already and there shouldn't be a side-effect as this was the old default as far as I can see. Hybrid probably knows more about this but I guess he's currently in holiday.

No, I'm back already. But I didn't test this so far. Should be visible in example 7 as well then. Maybe some state which is incorrectly reset in the stencil shadow setup.

It's really obvious in the Special FX tutorial (#8) which is where I found it.

Yeah, but only with DX 9.

Ok, stencil setup in DX is somewhat different to OpenGL. So maybe I have to clean some things up there. I'll move this to bug reports.
