tried many stuff now but i cant get it right

here is the c++ code i tried to clone as c#

// Get scene materials
Interface* ip = GetCOREInterface();
MtlBaseLib* lib = ip->GetSceneMtls();
if (!lib)
    return 0;
// Loop over the scene materials
const int NumMtls = lib->Count();
for (int i = 0; i < NumMtls; i++)
{
    // Get current material
    MtlBase* mtl = static_cast<MtlBase*>((*lib)[i]);
    if (!mtl)
        continue;
    // DxMaterial or extend ?
    IDxMaterial* dxMtl =
    (IDxMaterial*)mtl->GetInterface(IDXMATERIAL_INTERFACE);
    if (dxMtl)
        ProcessDxMaterial(dxMtl);
}

and now the c# implementation

IInterface_ID iidDxMat = SceneManager.MaxGlobal.Interface_ID.Create(1437802525, 699105219);

IMtlBaseLib MtlLib = SceneManager.MaxCore.SceneMtls;

for (int i = 0; i < MtlLib.Count; i++)
{
    IMtlBase mtl = MtlLib[(IntPtr)i];

    string strName = mtl.Name;

    IIDxMaterial dxMtl = (IIDxMaterial)mtl.GetInterface(iidDxMat);
}

the last line always gets an exception that i cant cast BaseInterface to IIDxMaterial.

what's the error. im banging my head since one week on my table due to this problem.

hello

would be great if its supported in the future.

right now im parsing through the entire paramblock2 and get each parameter by hand. this interface would make things a lot easier.

after we purchased the source from you i thought of looking into it and fixing myself *g*

but this takes more time when you do it ^^

P.S

why the auto assembly loading isnt working anymore ? right now i have to restart max in order to reload the plugin with new code. if i try theres always an error with some dependencies that cant be reloaded.

ok now the plugin realy wants to reload (other crash now)

but this time its an target invokation error.

i have seperate windows in my plugin and i remember tthe window settings with an xml file.

this xml file will be loaded on startup with the xml deserializer

if (File.Exists(a_strConfigFile))
                {
                    XmlSerializer xmlCurrentConfig = new XmlSerializer(typeof(UserConfig));
                    FileStream fsCurrentConfig = new FileStream(a_strConfigFile, FileMode.Open, FileAccess.Read, FileShare.Read);

                    try
                    {
                        confMaster = (UserConfig)xmlCurrentConfig.Deserialize(fsCurrentConfig);
                        fsCurrentConfig.Close();
                        return confMaster;
                    }
                    catch (Exception e)
                    {
                        fsCurrentConfig.Close();
                        Logger.LogMessage(e.Message);
                        return null;
                    }

(UserConfig)xmlCurrentConfig.Deserialize(fsCurrentConfig) this will throw an target invokation error.

the exception details show me that an object is not set to an instance. if im starting the plugin on startup of max all is fine.

i think something went wrong with reload plugins and the assembly cache ?

trying to solve this with dfeaulf settings in case this happens *g*

i tried to debug the steps but it wont step into the upcast functions

when i look inside those upcast function there is an entry with iidxmaterial
