Hi Ello,
It looks great and I had a few questions about the product.
About the framerate: How is the framerate affected? What is the frame rate of a level with the sky visible and then not visible on say a 30,000 x 30,000 quant level?
About the file size: Also, how big are thy sky map files? This is important for us developers that wish to make shareware demo's for our products.
Also, is there any way to determine if the sky does not work on a users computer video card? Because if it does not work then we can disable the sky and use a standard colored sky.
Thanks for the great work.
