Hi guys,
I am following this great tut by Rohan Dalvi.

But i am not perfectly understanding what exactly is the projection type outputed by the Projection UVW node.
It looks like a transform matrix.
But i am not understanding how the Texture Image use this matrix and what the matrix itself contain ?
Because in the tuts he use a simple 1D gradient. But i was wondering if by using a 2D gradient map like those,
it was possible to access to 2 channel info instead of 1?
And thus to scale the possible custom float attribute accessible in the shader from 3 to 6.
Thanks for your lights !
Cheers
Emmanuel
