Hi,   I want to write a modifier plugin. In the SDK article "How to write a simple modifier" I read that you need to inherit from the SimpleMod2 class, but I couldn't find this class. Is there a reason, why it's not implemented in the .NET wrapper or can I just use the SimpleMod class instead?   Thanks, Christian  | 
 | Hi Christian,   Not sure why you can't find it but it is there, this is from the Autodesk.Max.dll source code, located under Autodesk.Max.Plugins namespace:     public abstract class SimpleMod2 : Autodesk.Max.Plugins.SimpleMod, Autodesk.Max.ISimpleMod2 ...      Which Max version are you using? Marsel Khadiyev (Software Developer, EPHERE Inc.)  | 
 | Hi Marsel,   thank you very much for your quick reply! I'm using 3ds Max 2009 and it works with the ISimpleMod2. I was just a little bit confused because SimpleMod was a class, and I haven't looked for an interface...^^   Christian  | 
 | No problem Christian.   If you are writing a plugin (not just using another plugin) you should derive it from Autodesk.Max.Plugins.SimpleMod2 (not ISimpleMod2). This will make it pluggable. Marsel Khadiyev (Software Developer, EPHERE Inc.)  | 
 | I don't know why but the class Autodesk.Max.Plugins.SimpleMod2 can't be found. Only Autodesk.Max.Plugins.SimpleMod is available. Do I need to upgrade the Max.Net classes or 3ds Max?   Christian  | 
 | Yes, you're right. It seems Max.NET for 3dsmax 9 and 2009 doesn't have SimpleMod2 exposed, however 2010 and 2011 has it. I will look into why this happens and try to fix for next build. Marsel Khadiyev (Software Developer, EPHERE Inc.)  | 
 | Thank you. However, it is not urgent because I just figured out that I have to inherit from the Modifier class anyways.   Christian  |
