Using Custom Mesh
Hi,
I am trying to adapt the code to use my own custom mesh with NvBlast. I imported in Unity a mesh made with an external 3D modelling package and then I fed it to the CreateWall object in the scene (basically my own mesh is fed as the cubeMesh in the script). Unfortunately Unity crashes. On the other hand, if I try to feed one of Unity's built-in meshes (cube, sphere, capsule..), everything works fine.
After debugging for a while I realised that the crash occurs when the Fracture object calls setSourceMesh(nvMesh), so exactly inside the Bake method.
Any idea what is preventing my own meshes from working?
Thanks in advance
Hi no idea, I remember I had problem with meshes with holes or disconnected vertices (faces did not share vertices)

Thanks for the feedback. So I noticed that any mesh built in Unity works fine, even those with holes inside them (I made a few with ProBuilder). However, when it comes to any FBX made outside Unity, it won't work. For my project, ProBuilder is all I need, so I am happy. But for more complex shapes it currently does not work.
Here you go. It's just a simple wall with a hole inside, mesh should be airtight. I also tried with a simple cube made in Blender, the default one.. that also does not work,
So I just quickly assigned your mesh to the cubemesh field at CreateWalls:32 and it works as expected. I just changed the import scale factor to 50.
Mmn okay strange. Not sure why scale would be have to be changed. Could be a Unity version issue..? 2019.3.0f3
No issue in 2019.3.0f1. You could send me the whole project and I could take a look.
Ok, I'll try to isolate the issue in a single scene and send it through because it's quite a big project. Thanks for that!
I also have another question, but this is about batching of each chunk. I'll open a new thread for that.
