For this program I recommend you have either a
Tablet Computer (which I use) or
you have a
Wacom pad. This program can be challenging to use with
just a mouse but it's still a lot of fun.
ArtRage 2 is a paint program the simulates using real paints
but without the mess to clean-up. You can see paint texture,
canvas texture, metallic paints, several of the tools a
painter would use. You can use Oil paints, Chalk, Pencils,
Markers, roller... You can mix and blend. You can adjust
pressure, thickness, opacity... the list of features goes on
and on. Additionally you can add layers, import and export
images.
Here is a sample of a something I was working on in ArtRage2
