Hello,
for my project 'Commando Xenidis' I am building a 3D planet map. I am new to Direct3D. I am using Omega Headers based on Clootie-Headers for DirectX8.1. Screens can be found under projects/commando xenidis.
Those planets are X-Objects, just spheres, also is the sun.
1) How do I get animated clouds on my planets? Do I need to create a 2nd layer on my X-Object, a sphere that is a bit larger and give this layer a cloud texture? How do I make a transparent? Or is there a more simple way?
2) The sun only has a texture right now, how do I make a corona or another nice sun effect?
3) Is there a simple way to create some nice looking fog (Volumetric Fog?) or does anybody have other ideas for some nice effects?
I would be glad about some help or some ideas. The skybox does not look good I know, I am just switching it to another.
Thanks a lot,
Firle
