Hi, I have a really wierd problem. I'm new to SL building and have just made a mesh house and a physics shape to match. when I choose to upload the physics file to Second Life through the LL Viewer, It seems to have only chosen to use one 'Prim"??? from the physics file I uploaded, It says there are plenty of vertices and triangles, but it still only shows one Beam on the top of my roof as selected. I have joined the mesh in blender and it is as one unit. I used the default export settings for static mesh in blender Please help.. I'm in my first steps of blender and mesh uploading this week, and I have an ENOURMOUS amount of respect for anyone who has 'figured' it out haha :) Mickey
