3D-Coat - a convenient and useful program for texture and detail of 3D-objects, designed specifically for 3D-artists and designers, but is initially focused on computer games developers.
The program combines layers of texture and detail in one simple and intuitive interface. There is full support and compatibility of such packages as the Light Wave 3D, Modo format *. lwo, Maya, 3ds Max, Carrara format *. fbx and *. obj. 3D-Coat supports 3D SpaceNavigator of 3DCONNEXION for more intuitive navigation. The program can work in a strong bond with Adobe Photoshop and other 2D editor, working with PSD files. Performance program has increased significantly through the use of normal maps.

AKVIS Sketch
AKVIS Sketch is software for conversion of photos into pencil sketches and watercolor drawings. Now you do not need to handle a pencil to feel like an artist. All you need to create your original work of art is good taste and AKVIS Sketch. Our efficient method allows creating realistic color and B&W drawings that imitate the technique of graphite and color pencil, charcoal and watercolor painting.
In contrast to the similar standard filters (like the built-in filters in Photoshop or PSP) that offer an approximate sketch, AKVIS Sketch provides a convincing result; it comes very close to hand-drawn works of a human artist. Getting a similar result with the standard tools would require expertise in image editing and extensive manipulation with layers, masks, brushes and applying filters.
AKVIS Sketch has a neat interface with a few sliders. At first you can process the image with the default settings and then touch up the photo adding color, or trying different techniques - from pencil to charcoal or watercolor. You can make the hatching denser or finer and change the pitch angle of strokes.
Home users will be delighted by the neat result of the photo-to-sketch conversion. AKVIS Sketch can bring a lot of fun: a pencil portrait can be a good present for your relatives and friends, a watercolor drawing obtained from your last nature shooting can decorate your room, you can convert any photo to an original drawing to print on a T-Shirt.
