Non Volume-Based Collision Detection for Particle Fluids Nov. 9, 2007, 10:49 a.m.

Yes, the normals are facing in the right direction. You'll see in image01 that the volume it generates is actually resonably correct, i just need better detail in the more detailed areas of the model.

This hip file was sent to kleer001 privately, and no solution was obtained.

Non volume-based collisions appear to not work, so the only place to keep experimenting was with the volume collision guide.

I found I had to take the external surface off my object, and boolean the inside with a cube. This produced a reasonably accurate collision guide (see image01).

The settings for this volume can be seen in image02.

As soon as i raise any of the divisions to get more detail, the volume seemed to explode (see image03). In this instance the y element of the division was just raised to 35, and boom… unusable volume.

Remaining questions:

1) Can I create a better (custom?) volume?
2) Is there anything I need to do to get collisions working when I untick “Use Volume Based Collision Detection”

Hi Steven,

I had a peek at that dynamics pdf. I'm already aware of a lot of stuff that the paper mentions.

My main problem revolves around it not creating volumes that are accurate enough for my custom geo, despite tweaking.

And, like I said, the non-volume based collisions appear not to work.

So I'm afraid my two questions still stand.
