Transparent text in OpenGL

Hello,

I'm trying to display a transparent text on my scene using OpenGL renderer.
However this piece of code:

	fontStd->draw(L"Test text!",
	core::rect<s32>(100,100,300,290),
	video::SColor(alpha,0,0,0));

Doesn't let me control the opacity of the text.

I found a bug report with a patch on this forum (http://irrlicht.sourceforge.net/phpBB2/ ... ransparent), but it doesn't work.

I use irrlicht-1.0.

Thanks in advance,
iona

Is that being called every frame? If not, you are really passing a copy of the alpha value, so when alpha changes, the copy the font has does not. If so, then I'm out of ideas, sorry.

Yes, that code comes from main render loop

but thanks for trying to help,
