Please help me! When i want to open the coreshaders.mas to extract in 3ds max mas2.exe get an error "unknown mas". What can i have to do?
They don't need to be extracted. In fact, if you're using a more recent version of the plugins, you should be shown a dialog where you can point to the folder containing the ShaderGFX.MAS file the first time you start 3ds Max. That's all the plugins require.
