View Full Version : Lightwave 8 Dynamics 'problem'

Can someone please test this scene?
LW8 Dynamics scene (www.3dink.com/d2.zip)
It should work, but when I calculate the dynamics, the wall disappears.
Its pretty simple.
A broken up wall.
An emitter shooting particles at the wall.
A collision object, 'breaker' (that you need to manually FXlink by hitting 'm').
A floor object.

Normally, if you hand animate the collision object and calculate,
the wall will crumble. Try it, its fun.
But, when you FXlink the collision object to a particle, the wall disappears, sometimes LW crashes.
Shouldnt it simply work where the linked objects will hit the wall and it will crumble in the appropriate areas?

Here is a test (http://www.3dink.com/pfx8.zip)
The solution I was told is we need to bake the FXlinked objects keys and remove the fxlink before the rest of the calculation will work.
not that great a method... because any change requires redoing the emitters settings, reapplying the fxlink, rebaking their keys, and then recalculating the HardFX!

ill send this one to NT and hopefully we can get a better workflow going!

Try this one also..
Its just a collision object breaking up a wall. In the one scene, it kinda works, but the “bricks” sink down through each other to the “floor” if you don’t move the collision object quickly

The other scene attempts to fix that by turning on the self interaction..

Hit calculate, and it will start off, then come to a screeching halt…

Is there a 'make path' function for PFX just like the 'make path' in the softFX?
Maybe parenting the collision object to the path null is a slightly easier solution.
