Because of Download time all bit-maps are in the JPEG display format. So that one the files in the WED to use can have all pictures as BMP to be converted. If you do not have a conversion program, you can load the format transformation (JPEG - > BMP) from here a Tool with it become completely simple.

The presentation method of MDL Sky changed something.
The MDLs is to be scaled differently.
sky sky_blue {
type = <skysph008.MDL>;
scale_x = 0.1;
scale_y = 0.1;
scale_z = 0.1;
flags = scene,visible; //Flag nofog as required
layer = 1; // dependent on the other Layers
}
The representation and the scaling depend also on level size at the same time.

The files are in the JPEG format. One can convert those with nearly each image program as TGA. If you do not have such program, you can load here a conversion Tool.
