Masked textures?

Anyone know how to hide the color 0, 0, 0 on a texture so when its put on a mesh the black is not shown.

ive tried adding the flags to loadtexture to no avail, i will try multiple cameras to get round the problem next.

Masked texture behaviour differs to Blitz3D - instead of colour 0,0,0 being used, alpha > 0.5 is used instead.

ah i see, any way of making another command to mask the colour.

Simonh could you make a small example?
I tried loading a PNM with alpha chanell using this command:

Local tex:Ttexture = LoadTexture(path,1+2)

And it doesn't work... I still se the pixels that are black and have the alpha value > 0.5 as black

4 is the masked texture flag.

I can see the alpha system does allow quite a but of flexability the only drawback is images loose colour depth.
