Why isn't it working. I don't have a full understanding of mShapeInstance. I am guessing it is something to do with the fact that it use to be inheriting from TSstatic. Yet every StaticShape has cloaking that is doing the same thing (not positive it cloaking works). I am able to place the object, but the texture is the environment map and not my texture. Note: if you copy this into the RTS pack make sure and give the building it's own datablock as it needs one now.

Giving it a datablock:
go to starter.rts/server/scripts/items/building.cs and add:
datablock StaticShapeData(BuildingMarkerBlock)
{
shapeFile = "~/data/shapes/building/building.dts";
category = "Building Marker";

boundingBox = "10.0 10.0 3.0";
};

then go to starter.rts/client/scripts/playGui.cs. Then search for "$NewQuad = new RTSBuildingMarker()" and place:
datablock = BuildingMarkerBlock;
below:
thedatablock = "TestBuildingBlock";

If anyone knows why setOverrideTexture isn't working please help.

#2 The few times I've seen the "effect" you are talking about has been with a model that doesn't have collision mesh defined, and/or a bounding box.

My question to you though why did you change the inheritence? It's possible that the StaticShape class has an override in it somewhere that isn't designed for texture over-rides (that sounds confusing, sorry!).

Is there a design reason why you are moving RTSBuilding and RTSBuildingMarker to static shape? You'll be losing some functionality by doin so.

#3 Yeah to gain the functionality of animation for RTSBuildingMarker and rotation for RTSBuilding.

Note: We are going to make our own class or rename RTSBuilding, once we get this RTSBuilding working, because we are not using them as buildings.
