Is there a way to import a design file (.jpg, .png, .bmp etc...) and use its alpha values to shape a plane? I am using jit.gl.sketch to create a plane and then using a .jpg with jit.matrix to texture the plane. But this leaves me with a square plane. It would be nice to transform a plane to a more complex shape buy using the alpha channel from an imported file. Any ideas?

1. make sure you use a 4 plane matrix, or use jit.gl.texture

2. as far as I know, jpg does not support 32bit images, meaning they 

3. use the settings depth_enable 0, blend_enable 1 and mess around

1. make sure you use a 4 plane matrix, or use jit.gl.texture
2. as far as I know, jpg does not support 32bit images, meaning they  
have no alpha channel.
3. use the settings depth_enable 0, blend_enable 1 and mess around  
with the blend modes on jit.gl.sketch.

i guess that should've been depth_enable 1
