Why is bouncing up objects? Why is shaking objects?

#1

Hi all,
I have some questions? Please help me…
My English is a little worse. I’m Sorry.
Please watch the videos…

1-) Why is bouncing up objects?

2-)Why is entering into the objects box.

3-)Why is shaking objects?

Thanks All my friends…

Use Dropbox or Google Drive please.

OK. Added dropbox links…

For the bouncing and shaking objects there’s a few things you can try.
1st, increase the subframe sampling.
2nd, as soon as particles get in the desire position, send them to another event.
3rd, mP Drag :slight_smile:

For the interpenetration problem, have you checked the collision shape of the bigger object? Maybe you should give it more detail.

#5

Thank you, but I can not. I’m trying. The problem can not be resolved…

I ask you. You can Example offer work? Please help me. :frowning:

#6

For one reason or another Default mP World Gravity works out to be 386.088. That is the value you should use. You are pounding those coins into the deflector and into themselves. Your forces are way too high. You may be able to compensate with very high Subframe Factor

Also you should never scale your collision geometry, only if there is no other option. Sometimes physx does not respect the scaling properly.

Since the particle shape is simple. Simulation with a cylinder and replace with complex geo using Disk Cache Post Operators Shape technique.

Thanks, i tried. But not working… Because you’ve chosen the Shape Instance “cylinder.” But, I use the Shape Instance “TAS” (object).
Slip and tremor continues. Shaking continues :frowning: Please help me ?

#8

Sorry lost in translation?

Use Cache Disk Post Operator Shape!

I know my english is bad. Sorry.
But, Your technique does not work… The problem continues. :’( :’(

#10

It works for me. :shrug:

That technique does work with your scene. I tried it.

I have used it dozens of times. So have many other people.

The scene I gave you is arranged that way.

I am sorry if you cannot figure it out.

Which version are you using Alex? I’ve it tried on max 2014 and it’s working just fine.

I using 3ds max 2014… :frowning:
