Run time backwards? Or export spline from PhysX?

Run time backwards? Or export spline from PhysX?

Postby broink » Friday, 25.April 2014, 19:09

Hi again!

I was thinking, is it possible to run time backwards?

Basicly what I want to do is have something pre-exploded and a scene where it is repaired / drawn together. I was thinking something along the lines of just making an animation-script in the PhysX operator with
Code: Select all
time = 1-time;

but it has no effect.

One way to do it would be if I could export the "explosion-path" as a spline, save it for each part and then run the spline backwards. If it is possible somehow to get the spline.

The last attempt would of course be to calculate 26 individual splines, but that is just... unelegant?

Hi.
Wz4CE can't bake physX animation yet. Maybe ikam will implement that some day...

A no brainer, but it might work for you ;)

Yes, as Skinnytorus said, physics backward simulation is not possible (not supported by Physx library).
To do that, a solution would be to record the physics simulation and create a player operator to replay it with cool options like backwards, speed control, etc... but sorry not planed for now.
