A small thing you could already change to improve your map (requires mrs packer/unpacker and a few files from Battle Arena and Town map).

  1. Remove the sky plane from your map since there is a better way to have a decent sky
  2. Unpack your map file and open yourmap.RS.xml and add the following code into the xml file
    Code:
    	<OBJECTLIST>
		<OBJECT name="Town_obj_sky_daylight.elu">
		</OBJECT>
	</OBJECTLIST>
  3. Add the files Town_obj_sky_daylight.elu, Town_obj_sky_daylight.elu.ani, sky_daylight.bmp & sky_daylight_cloud.tga into your folder and pack the folder


That should get you a nice round sky with moving clouds.
