There is a limitation, done by LindenLabs, affecting the the hollow-value in cylinder-primitives. It is limited to 95. All values above are automatically reduced to 95.
But there are some viewers, that didn't have this limitation included: As exapmple:
This viewers allow to set hollow to 99. And osgrid allows this at well.
If you build with this viewers in SecondLife, the value is "corrected" by the secondlife-grid to 95, if you try to set a greater value. In osgrid, as i said, greater values are possible.
Now the problem. if you build something in osgrid, using the possibility with hollow-size > 95, then your buildings look different: depends from the viewer you are logged on.
The reason: Even the rendering is limited. A Viewer, that is limited, will render the object as it were builded according to the limitation.
i avoid this by considering the LindenLabs-limitation. It is the only way to make sure, that all users see your building in the same manner.
Here are examples:
This you see, if you build something in osgrid with hollow-size=99. This pic is made with firestorm:http://im.bilderkiste.org/4133583327884 ... 4mtest.jpg
And this is made from the same position with the lindenlabs-viewer:http://im.bilderkiste.org/7133583331651 ... 4mtest.jpg
