For the fourth consecutive release of Max, this bug still remains.
I last worked properly in Max 8. It was broken in Max 9, 2008, 2009, and in Max 2010 it’s still not fixed.
I’m taking about the Collision Pairs in Reactor.
There are (should be) two methods for defining collision pairs in Reactor, that is enabling/disabling collisions between two rigid bodies in an RB collection. One does not waork at all, the other works sort of, but not as it should.
The first method is with the buttons, you select the pair of objects, then click the button, either Enable or Disable, but the buttons remain grayed-out at all times, so it cannot be used.
The other method is to press the button for Define Collision Pairs, to open the dialog box and define the pairs from there. When you open the box, it should list all the objects that belong to an RB Collection, insead it lists every object in the scene, not just those unhidden, not just those in RB or other Reactor collections, but every last little thing in the scene, so you have to scroll through them all in the little list in the box. When you eventually find the object, you must then find the other half of the pair in the second list, which again includes every object in the scene. Then repeat the process for every collision pair you need to add. Not a real big deal in a modest scene, but in a heavy scene with many objects it’s beyond tedious and a huge waste of time and concentration.
1. Start a new scene.
2. Create a number of primitives, at least 6.
3. Create an RB Collection.
4. Add half of the primitives to the RB collection.
5. Go to the Utillities Panel, choose Reactor, open the Collisions rollout.
6. Select two objects that belong to the RB Collection. Note the Selected Pair buttons are disabled.
7. Click Define Collision Pairs. Note the Entities list shows all the objects in the scene.
8. Select one of the RB objects in the list. Note the Enabled Collisions list shows that object paired with every object in the scene.
It’s about time something was done about this.
Here is a thread about it from April 2008. And this one from October 2007.
