Step 2 - creating a texture painting script
We've now created a shader that accepts two textures as input (the top and bottom
textures) and blends the top over the bottom; this allows alpha transparency.
This results in a Photoshop-layer style effect. This allows us to separate texture
painting onto a top texture while preserving the pixels of the original background
below it, as shown here:
Creating a texture painting script
Before moving further, however, we must first edit the brush texture asset we
plan on using via Object Inspector. Specifically, select the brush texture from the
Project
panel in the Unity Editor and change
Texture Type
to
Advanced
. Enable
the checkbox for
Read/Write Enabled
; this allows the texture to be accessed using
texture-editing functions.
