Hi.
When i export from Zbrush my tool to .stl file, the programm create a file with a size of 1Kb. In MagicsRp, i import recently created file. and it types me that
the siza of the model is too small.
In Zbrush i try too Unify my model; use Deformation - Scale and increase size of the model in 20 -30 times; Update size Ratios, but was the same effect… 
In Zbrush3.1, I created from my tool .stl again and imported it in MagicsRp. Everything was ok.
What’s wrong with R3 version ? How to fix it ?
