Hi Adam,

I've make a new VE demo to test this out:
http://visionegg.org/trac/file/trunk/visionegg/demo/texture3D_alpha.py

It seems to work for me. Does this demo work for you?

Cheers!
Andrew

Hi, I've got an image file that I'm using with the textureStumulus3d
class. The image is a png with alpha channel.
when I display the image though, the background is shown as white.
i'm using the following code to load the image based on the demo.
should I be setting some openGL parameter beforehand?
thanks

filename = ("frog01.png")
texture = Texture(filename)

stimulus = TextureStimulus3D(texture=texture,
                            shrink_texture_ok=1,
                            internal_format = gl.GL_RGBA,
                            mipmaps_enabled=0,
                            texture_min_filter=gl.GL_LINEAR,
                            texture_mag_filter=gl.GL_LINEAR)
