Hello guys, because rejecting a Blend-File by blendswap i wrote this little addon. These addon switches on or off the Mirror- and / or the Subdivison surface modifier for the viewport of all objects in the scene. The behaviour of the viewport is faster if these modifiers are off naturally :-). The file includes the addon and a short demo scene for trying the addon. Unzip the file, open blender and in the user preferences under "Add-ons" choose "Install from file ...". Choose the Mikel007Panel.py file and switch on the appearing addon in the list. In the left panel (i´ve forgotten the name of it :-)) of the viewport you can find the Mikel007 Panel. I hope you can use this addon.
With greetings, Mikel007.
um dont get it, vid?
