Doesn't work.
Does that mean the only way to solve this problem is to reduce the number of the objects in 3ds file or to use Web Start instead of Applet?

save locations of others to a text file?   I don't know how to do this in 3ds max. could you please give me some details?
Thanks

Thanks for your advice.
I will change it in 3ds max

For example, I have two 3d objects in 3ds file. the two objects have a little bit overlapping, so if I load these and merge these into one object by jPCT, the part of overlapping will a little bit flashing after applying deferrent texture. Look at the following code:
    for(int index=0;index<terrainObjs.length;index++){
           obj = (Object3D) terrainObjs[index];          
           if(obj.getName().indexOf("track_ground")!=-1){
             obj.setTransparency(1);            
           }
           terrain = Object3D.mergeObjects(terrain, obj);
         }

but I notice that the object's properties I set before merging will be missing after merging, so the object named "track_ground" in terrain is not transparent. That's the problem about opacity, right?
So how to set the property of such a object which will be merged into another object?

Ok, I will send you the 3ds file immediately.

The instance of object exists when I open the 3ds file with other tools like 3D Exploration, but is missed when loaded by jPCT.

You mean set the value as "Config.glMipmap = true;", but it doesn't work.

in my 3ds file, some objects are instance objects, I found jPCT can't load this kind of objects by Loader.load3ds(), any way to load?
