Fracture OBJ Problem

[johnsonmax]

Hi,

 

I'm new to Houdini so this might be a very silly question.

 

I'm playing with Voronoi Fracturing.

 

I got it simulating with a small cube but when I replace that cube with a simple stair.obj model, it seems there is some gaps. It still has a different simulation/effect.

First you can turn on "check box"

Show Collision Guide Geometry

 

are you using Bullet Data

try switching to RBD solver for the Collision ,

this way the Collision geometry will match the shape of the Object

 

Here In the Snaps.

 

Put up the scene to help you fix it

 

cheers

Thanks Mangi

 

Here is my file

 

Yes, I'm using a bulletrdbsolver

 

How would I switch?

Hi Max.

First comment on your file

The stair models is pointing to your hard drive:

C:/Users/Max/Desktop/spareShit/stairs.obj

can you send it please.

Max

look into these examples 

 

FractureExamples 

In the Houdini help Examples:

 

Because there is a 1000 ways to skin a cat.

 

Cheers

Max, well I was waiting for your upload of the stair model.

I made one myself just for the  test.

 

I guess with some tweaks you can get a collision working okay in your example 

& the bulletrbdsolver

 

This would be the result:

 

cheers

and good luck with your training with Houdini

Thanks mangi!

 

I'm looking at your example file now, ill let you know what happens.

 

Just got back to this and seen all your messages, sorry about that.

 

Thanks again man!
