* AMD graphics card support Radeon HD 7850, HD 7950 and FirePro W7000, W8000 and W9000 have been officially tested and added to the Tested Graphics Cards list.
* Vector Paint and Vector Inspector tools give you the ability to create flow and normal maps to specify the direction of paint flow on a model, and to monitor changes easily with the inspector.
* Vector paint blending modes help create flow and normal maps with the specialised Vector Paint tool.
* Vector shading modules assist in creating flow and normal maps by setting the vector field information, displaying flow visualisation.
* New brush cursor options mean the brush cursor for the Paint tool can be changed to display an outline of the currently selected brush.
* Projection Cube and Projection Sphere shader modules allow you to project cube map or spherical texture files onto geometry for a faster workflow.
