hi all,

how do i deform a softbody shape by particles?

i used the following method:

1. create softbody
2. create emiitter
3. assign radial field to particles -> 'use selected as source' (on a PP basis)
4.make softbody be affected by field
5. make particles collide with shape

this way the softbody deforms nicely under the influence of the external particles, but those particles still penetrate the shape no matter the collision detection.

what am i doin' wrong? i want the softbody to look like being deformed while filled up. :shrug:

You should use springs to maintain the shape of the geometry, if not, the surface will turn insideout.

nono, i already know that! deformation is not the problem.

i want the particles to collide with the geometry, while they keep on deforming it.

think of some comic style tube that bulges as something gets pushed through it.

i want the particles to be bubbles of air, deforming the shape of an organ, while rushing through it.

In answer to your question :

"5 - make particles collide with shape " is not sufficient

you have to use the the DYNAMICS RELATIONSHIP and confirm the collisions between particles and softbody.

if you want, look at :

cool, i didn't know that i have to explicitly set that relationship in the editor.

thanks a lot! :thumbsup:
