No worries. Probably because MV3D basically re-writes the tilemap class then in order to make everything 3D as it does then, lol. I have to basically avoid most map/tileset altering plugins for obvious reasons.
Funnily enough, had it of worked, that function could have been handy for me last week; as I actually tried to implement icon labels for autoruns and 3d model events then but they become too much hassle to hide away (I need to sink them beneath the ground in 3d).
Thanks for the prompt reply.
