Have you ever placed objects in quite casual in a scene? Coins on a table, marbles in a container, even the rocks along the beach… it’s a quite boring and hard work.

In such cases, you first – reaching best results – using the physical simulation. The Physical simulations are weapon every day under the eyes of all: smoke, water, electricity and even actual physical contact between objects.

Concerning the simulation of physical objects in 3ds Max we have a plugin (for years now incorporated) which is Reactor. Powerful and complex tool that I can not describe a single post!

The best thing is to see him in action now! So to give you an idea of how quickly you set a scene with objects physical collision, I did a quick video. I created some inclined planes and 4 / 5 balls. So I gave it mass=0 to the plans (if no weight is not moving!) and mass=1.0 to the balls and … it’s done:

• RB Collection (Reactor) setting –  Video / 3mins

In conclusion I link you a tutorial from Evermotion.org that explains how to simulate coins falling on a floor, with the same principle as the previous video:

• Coins – Tutorial Evermotiong.org

The concept is very simple: Just put an RB Collection object in the scene, involve the various items, get the “weights” and just run the simulation. Truly instant!

Have fun!
