Transparency (alpha channel) ?

[Methuselah]

How can I use alpha channel transparency with textures?
The 'textures' part is optional, I am trying to draw a 2d image with transparent edges

[bitplane]

for scene nodes,

node->getMaterial(materialnumber).MaterialType = video::EMT_TRANSPARENT_ALPHA_CHANNEL;

for a 2d image, driver->draw2dimage has an alpha flag if i remember correctly, or you can just use a gui image.

try reading through the examples, they're very useful
