In 3D programs you always need a certain projection method to apply textures on objects. The most common projection methods are spherical, flat, cylindrical, cubical and, of course, UV. UV maps use their own grid which is independent from the object, and you can transform UV polygons and vertices without changing the shape of the parent object. With RealFlow's grid fluids you can calculate displacement maps from the surface and store them as 16-bit images. This panel provides parameters to control the mapping process. Please keep in mind that these parameters are only valid for RealFlow's “Hybrido mesh” engine.
