Ease of use:

Have some experience in 3DS MAX? We suggest you to try PARA! You will find it extremely easy to use and understand. PARA 3D is designed to be as easy and user friendly as possible, and therefore early on it was decided to keep the layout and system similar to Material Editor in 3DMax, so as to cut out any learning/training period once beginning to use this new software. Everything can be done by simply dragging and dropping the chosen tool(s) and manipulating the values to whichever degree is required.There is an almost unlimited combination of tools that can be merged.

Is PARA 3D for me?

PARA 3D is the antithesis to the traditional approach of Architects borrowing software from Animators. Instead it is designed primarily for Architects and Designers. This is shown by the fact that no programming background is required whatsoever, and anyone should be able to use it; as a result of its ease of use. PARA 3D is very useful for various other disciplines including motion graphics and visualization. However, due to the power hungry and speed conscious applications that Animators invariably require, a quicker version of PARA 3D is currently under development. More updates to follow soon.
