Stencils:  Real Time Texture Splatting


Create a new Texture for the Stencil

A stencil is a black and white texture.  It is placed between the 2 textures you want to merge.  White makes the top texture transparent so you can see the texture under it.

Stencil name and size

Give the stencil a unique name.  For this tutorial, I'm naming it Stencil-ground.  Because this is for the game engine, the stencil size should be a power of 2 -- 32 x 32 or 64 x 64 or 128 x 128 or etc.  For this tutorial, I'll make the stencil 512 x 512 pixels.
