Hi, thanks but i managed to fix it. It wasnt a Cinema4d related error. Apparently a bad argument to one of python methods was causing it to return the filepath of the script instead.

damn. totally didn't look there. sorry. Alfie

Hello, LoadDialogResource() and LayoutFlushGroup() should work perfectly fine together. Typically LayoutFlushGroup() is called in reaction to some user interaction or in InitValues(): Bool CreateLayout() { if (!GeDialog::CreateLayout()) return false; if (!LoadDialogResource(11000, nullptr, 0)) return false; return true; } Bool InitValues() { LayoutFlushGroup(11003); AddButton(100, BFH_SCALEFIT, 0, 10, "Button"_s); LayoutChanged(11003); return true; } best wishes, Sebastian

Thanks for the solution and explanation Yannick. It's working perfectly now and I can finish converting my scripts.

Cool. Will do.

Hello, please post questions on Cinema 4D plugin development in the "Cinema 4D Development" forum. When doing so, please also use the appropriate tags. MATERIAL_GLOBALILLUM_GENERATE is the correct ID of that parameter. You just have to set the parameter value of the material you want to edit: material->SetParameter(MATERIAL_GLOBALILLUM_GENERATE, false, DESCFLAGS_SET::NONE); please notice that the ID is defined in the millum.h header file. If you have general questions on how to handle materials with the C++ API you will find information in the documentation: Materials and Shaders Overview BaseMaterial Manual Material Manual best wishes, Sebastian

Hello @iluxa7k, I just move this thread to the "Cinema 4D Development" forum. When creating a new thread, please also always add the proper tags. best wishes, Sebastian
