physis mesh not uploading

[aht1981]

Hi so over the years I've made various items and sometimes have done my own physics mesh - usually they appear in the uploader and can analyse to fix the problems- hurrah! But sometimes - usually with bigger buildings I've noticed it's not appearing in the preview window. If I upload the option to convert to prim is not present - but even sometimes with smaller builds. Would somebody be willing to have a look at my build and suggest why the physics is not uploading. I've managed it before with buildings so I understand elements of it, but just want to be able to sort this. Thank you.

The uploader has changed a bit recently.  I just tested though and my physics model is working as it should.  

Are you uploading your OWN physics mess using the PHYSICS tab?   If so there is likely something wrong with your  physics model.  It should be VERY SIMPLE and that is what most folks mess up. If you are analyzing you also need to make sure that the resized CUBES do not touch each other.

 

Here is an old video (previous interface so ignore all that ) that basically explains what you need to do. Hope that helps.

hi thanks for the respone. I am using my own physics mesh and I'm using plane physics not cubes.

Could be that you are uploading multiple mesh objects in a single dae file, but you don't have a dedicated physics mesh for each object in your physics dae. Make sure that there is the same number of physics meshes as there are visual meshes. When uploading multi mesh dae, use this naming convention for the objects:

I had a look but not sure it's that - just as this person is trying to upload multiple meshes and I'm only doing one mesh and one physics mesh. I can share the files or log if somebody wants!

Sharing the file is almost always the quickest way to getting a solution to your mesh problems.

If you post a link here then I am sure one of us will have a look at it and if necessary do a test upload for you.

If it's supposed to be just a single mesh object, make sure you have "export selected only" checked in the export settings.

If it rezzes as a linkset in-world, you know there is something in the dae that shouldn't be there.

so I checked the version I have inworld and I think, even though in blender it is one item, it's 3 linksets. I used edit linked and could move half the building. During creation things like the window frames were made as seperate objects and then "joined" to the build. On export I always used "export selected".

OK, next the number of materials come to mind. A mesh can have up to 8 materials in SL. If it has more, the importer will split the mesh into multiple meshes to stay within that restriction. Coming out as 3 objects, you would need to have at least 17 materials assigned to that mesh, though.

For a house like structure, I would recommend to use separate objects for window frames and the like. Otherwise all these little triangles count against the size of the whole building, which may increase the Land Impact unnessecarily.

[aht1981]

Right so this makes sense as we have 19 materials!!!! I'll have a go seperating things like the frames and glass after badminton and dinner!

there you have it then.
