Hi,
I've been playing around with the cloth system applied to a sphere in order to make a balloon colliding with the ground

(i'd like to make it like The Ball in the tvshow The Prisoner actually)

the thing is that after looking up in the “material” tab of the sphere in the DOPnetwork I still don't really get how to achieve the behavior of a realistic rubber (for instance the geometry won't really get back to its initial shape if I want it to bounce)

I don't really get the difference between the shearstiffness, the stretchstiffness , and if I should use the plastic hardenning or plastic flowrate and so on. And the range of values I should use

anyway I would really appreciate any advice about this or maybe someone here allready have achieved this effect …


all answers are welcome here

thank you guys

cheers

anyone ?!

I also tried with metaballs… I really have any clue…

if anyone has any idea please let me know

thank you

try to play with the bend stiffness
set it really high and you should get some softbody look
or use the squishy object

yeah I think the squishy object will give you what you need, it deforms and gets back to shape easily and I think it calculates faster that cloth.

there is one disadvantage of squishy object over cloth for softbody sim
sqishy objects are simulated as particles and i think you can't get mutual collisions between two sq objects
so if you need only ball/ground collision go for squishy object
if you need ball/ball collision, it probably won't work in one simulation, but there may be some workaround i am not aware of

thank you guys for your replies
I tried with the squishy object which will work perfectly for my purpose.

I'm working on a little issue during rendering now but it's the right method for sure

thank you again

regards

actually the problem is more tricky than I thought

so everythng works fine , but I can't get rid of the particles guides, they appear as spheres in my render .. I don't get it ….

I don't see any options for those

do you see what I'm talking about?

thank you

cheers

append delete sop after dopimport and delete the last primitive, which should be the particle system

hmmm, I'm not sure to get it
i appened a delete sop after dopimport as you told me ..then I put the popnetwork in the “pattern” of my “delete by pattern” option (am I right so far? )

I played around with the others attribute like changing the “geomerty type” and thoses kind of things but it doesn't seem to change anything
am I forgetting something important?!


thank you for your reply by the way

regards
