some simple questions

hi guys,
i am newer, i want to ask is Ogredotnet.dll and math3d.dll and dotnetbuilding.dll needed when build Mogre project?and where to get it?what'more how to use it ?

Thanks!

theses dll are not needed. all you need is mogre/ogremain dll (with it's plugins) and depending of the tutorial you try to build, mois.dll. Some of the tutorials refer to ogredotnet, and you cannot use the source code right away, you have to make some change to make it work, but it's usually really easy.

everything you need to build mogre tutorials are included in the sdk

Thanks.
