help: mesh physics doesnt match mesh model

[Ofelian]

i'm trying to build my own house, i made physics model just deleting extra faces from mesh model but when i do upload it on betagrid physics is stretched. Can anyone help me solving this?

Are those black parts of the preview part of the model that you removed in the physics mesh? If so, you  need to be aware that the physics model (of each mesh object if there are more than one) gets stretched and/or squashed to fit the bounding box of the high LOD (reference) mesh. To stop that distorting the physics, you need to make sure the physics model has the same bounding box as the main model. In this case, you may have to add back some geometry to bring its height to the same as that of the visual model.

Otherwise, if those are parts of the physics, so that the physics is taller than the visual model, there may be some extra geometry up there in the visual model that isn't meant to be there. In some circumstances, this can be invisible in the rendered model (even just a single floating vertex if it's the first in the file). So then you need to check that there is nothing that got left up there by mistake.

Here are some screenshots (Google Album) that might help if you are a visual person.  This is using CUBES for the physics model (necessary in some parts of OpenSim and that is where this was uploaded). Cubes or planes work fine in SL but I don't understand planes all that well  so I use cubes. 

Be sure and apply location, rotation and scale to BOTH your house model and your physics model. And TRANSFORM  --- Origin to Geometry. Not doing so can cause issues also.

 

After you get your house or piece of house uploaded you need to change the Physics type to PRIM in the Features tab of the build menu -- in case you didn't know that.

Thank you very much Drongle e Chic , that stretching on physics has been solved adding some faces to physics  geometry.

Now can move to baking, wish me good luck

The bounding boxes don't match
