Adding collision detection

Whenever we're adding deflectors to a scene…so as to create a collision detection system,…it is, generally speaking, a good idea to…keep things as simple and minimal as possible.…All necessary complexity in our deflector…setup will only slow down calculations, which…can, of course in turn, negatively effect the quality of our final result.…In order to start our scene setup then, we're going…to create the simplest of the deflector options that we need.…Which will be the one acting as a stand in for our table top geometry.…

In the create tab then, let's click to enter the space…wrap section and from the drop down list, select the deflectors entry.…All we need in order to do the job…effectively here is create a simple play now deflector.…We do that by means of the standard deflector option.…So, let's click the button to enter create mode.…And then, in the top…viewport, left click and drag to draw out a…deflector that encompasses the area of our table surface.…Remembering of course to right click in order to end the creation process.…
