Hello!
My plugin is conflicting with Redshift 3.0.20. Cinema 4D loads infinitely until i disable Redshift, then it loads and plugin works.

Commandline.exe doesn't show any error, each plugin loaded.
Project was compiled with Visual Studio 2017 v141 std17 in Release, Windows 10. Plugin has it's own unique ID from plugincafe.
How can i find out where conflicting part is?

Hello! I have a problem with my deformer plugin.
Plugin not only deforms shape of an object, but also adds new polygons and points to it.
Problem appears when i try to use isoparms mode.
What i figured out:
Problem was in SendModelingCommand(). It was solved by making new document, executing passes and copy to original object.

Bool DeformerPlugin::Disconnect(BaseObject* main, BaseThread* thread) {
	BaseSelect* select = ToPoly(main)->GetPolygonS();
	select->DeselectAll();
	AutoAlloc<BaseDocument> basedocBuffer;
	BaseObject* clonedOp = (BaseObject*)main->GetClone(COPYFLAGS::NONE, nullptr);
	basedocBuffer->InsertObject(clonedOp, nullptr, nullptr);
	basedocBuffer->ExecutePasses(thread, true, true, true, BUILDFLAGS::INTERNALRENDERER);
	ModelingCommandData mcd;
	BaseContainer bc;
	bc.SetData(MDATA_DISCONNECT_PRESERVEGROUPS, false);
	mcd.doc = clonedOp->GetDocument();
	mcd.op = clonedOp;
	mcd.mode = MODELINGCOMMANDMODE::POLYGONSELECTION;
	mcd.flags = MODELINGCOMMANDFLAGS::NONE;
	mcd.bc = &bc;

	if (!SendModelingCommand(MCOMMAND_DISCONNECT, mcd)) {
		ApplicationOutput("Disconnect error.");
		return false;
	}
	clonedOp->CopyTo(main, COPYFLAGS::NONE, nullptr);
	clonedOp->CopyMatrixTo(main);
	clonedOp->CopyTagsTo(main, NOTOK, NOTOK, NOTOK, nullptr);
	return true;
}

I should mention that plugin works well with polygon mesh objects and problem appears only with generator objects in isoparm mode.
I guess problem is in Isoparm lines. I've tried to use BUILDFLAGS::ISOPARMS. I cannot use it with non-generator plugin. But i saw few plugins that change count of polygons and still work good. And due to my logic in code i cannot change plugin type to generator.

Although creating a temporary document has been a solution, it still doesn't work good. Cinema4d crash appears randomly while i'm testing it. Usually it happens when i reduce amount of detail, i guess it is something with caches.

What isoparms even are? Why should i use it and how to prevent cinema from crash?
And what about SetIsoparm()? Can i use it in deformer plugin somehow? And should i?

@m_adam Maybe i'm little misunderstood you. I meant not exactly third case. But a case, when you start holding your mouse at empty space and selecting objects with outcoming rectangle.
