So in a broad sense I'm trying to apply a texture with alpha properties to a jit.gl.sketch object so it creates a nice brush effect.
If you take a look at the patch below, Nesa created a texture by using brushtips.mov, and some clever alpha stuff.
I understand how this works with jit.gl.gridshape [plane], as the erase_color is set to 0 (nothing gets erased), and the series of planes with brush images create a nice brush effect.
However, I tried to then send this texture to a jit.gl.sketch, to see if I could get the brush effect on the stroke, I tried this by setting the jit.gl.sketch [@capture] to capture the brush texture from the patch below, however it only seems to receive the color of the texture, but not the alpha content/effect.
Now my conclusion is that jit.gl.sketch just simply doesn't allow alpha values for a captured texture, however I'm hoping you guys can prove me wrong!
