[SOLVED] Obi Softbody BIND SKIN not working

[netjeenpetje]

Hi,

We have a model that we wanted to bind skin on, and it worked fine, but after working on it for more it just stopped working all of the sudden. We can see that the particles for debugging move, but the mesh itself isn't moving. What could cause this problem?


Btw, is there an Obi discord channel?

Hi,

It's hard to say without knowing more about what changes you introduced since it last worked. If you're using some kind of version control system, you could simply go back to the latest working commit and work out any differences, but otherwise it's pretty much impossible to say without looking at the project directly. I can only give you a couple basic pointers:

- Make sure the mesh has "read/write" enabled in its import settings.
- Make sure you've hit ObiSoftbodySkinner's "bind skin" button after making any changes to the softbody blueprint.
- To rule out any scene serialization issues, try removing the ObiSoftbodyComponent and then re-adding it and clicking "Bind skin".


kind regards,

Hello, thanks for the quick reply.
We already tried the possible solutions above. It seems like this problem happened after we exported the model with the correct scale parameters in the blender export settings.
Does that give you a clue of what couldve gone wrong?

Hi,

What do you mean by "correct scale parameters" in this context? There's no single "correct" settings when exporting a mesh, it all depends on what your goal is. Typically you'd want the transform scale to be 1 in all axis, so that the mesh size is consistent with world space units (1 meter in world space = 1 meter in object space).

What's the transform scale of the mesh in the scene? Also what are your ObiSoftbodySkinner component parameters?

kind regards,
