    Hi all,

    I'm trying to do something rather simple, disable the reflection channel on a material.

    I've tried both of these

    newMat->SetChannelState(CHANNEL_REFLECTION, false);
    newMat->SetParameter(MATERIAL_USE_REFLECTION, false, DESCFLAGS_SET_0);

    Neither have any effect, however they both work flawlessly in the Python console within c4d.
    I'm not having issues setting any other channel, just the reflection channel

    in which context are you trying to do this? Is it a script? Or a scene importer? Or something completely different?
    If it's in a SceneLoaderData, you probably have to set REFLECTION_LAYER_IMPORTED.
    See here the Material manual. Or this blog post about Cinema 4D R16 Reflectance channel's API.

    Blah I somehow missed that while skimming through the material manual. It is a SceneLoaderData plugin and that absolutely did the trick, thank you Andreas! 🙂

    my code for reference

    newMat->SetChannelState(CHANNEL_REFLECTION, false);
    newMat->GetDataInstance()->SetBool(REFLECTION_LAYER_IMPORTED, true);
