C-Hook Adding Custom Material to the Material List

[zero_divide]

Hello,

I am getting a material from the Material Library and then Adding material with the following 2 methods (C++/CLR code):

	bool COperation::GetMaterial(String ^ mat_name, CMaterial ^%ctp)
	{
		bool result = false;
		ent opEnt;
		if (TpMainMatMgr.GetMainMatList().DatabaseRetrieve(mat_name, opEnt))
		{
			ctp = gcnew CMaterial(opEnt);
			result = true;
		}
		return result;
	}

	bool COperation::AddMaterial(CMaterial ^ctp)
	{
		bool result = false;
		ent opEnt;
		
		String2CharA(ctp->name, opEnt.u.matl.name);
		String2CharA(ctp->comment, opEnt.u.matl.comment);
		
		if (TpMainMatMgr.GetMainMatList().Add( opEnt.u.matl )>0)
		{
			result = true;
		}
		return result;
	}

I am ONLY setting the name and comment at this point.

It works just fine and the new material is in the list.

Yet when I re-open MasterCam, the material is gone.

I am sure there is something simple i need to do to make it save, but just can't figure out what is.

Thanks in advance!

Tried to use this one:

TpMainMatMgr.GetMainMatList().DatabaseAdd(opEnt)

Still no luck
