its important as indie developers we need a modern paint tool specially with hand-painting style.
Yeah this will be nice for Maya Lt.
I want to spend painting in Maya rather than other software like about 80% Maya or 100% and 20% Photoshop.

this is just example interface and how will be easy to use when painting.
*Paint tool :
brush - eraser - gradient - fill - color picker - selection etc...
*Color :

*Brushes + Brush settings :
pressure for opacity,flow and size, etc...
*Texture editor :
able to paint on it or fill color on UV island
*Layers :
able to save it as psd or send to Photoshop
*Quick Baking Ambient occlusion
*Alignment :

Maya have problems in sharp area or low poly when painting on it :

so I hope this tool enhance so it become a good tool for painting especially for stylize painting.
