Transparent bits

Unity Engine
1

Hi all.

I’m an absolute newbie with Unity, so I’m really struggling with some things that I could do in Blitz3D with my eyes tied behind my back.

I’ve searched the forums, but I just can’t find the joy I crave.

Can anyone help me with this one?
I’m creating a simple side-scroller, in 2.5D.
My main character is a box, with 0.001 z-thickness, and I project its texture onto the face visible to the camera.

The problem is that I can’t figure out how to make the colour around the character transparent.
The texture is a .png.

Many thanks for any suggestions.

the transparency is done in your 2d program where you create the character in combination with one of the alpha shaders in unity

Ah, I see.
I’ll give that a go.
Thanks for your help.
