Spherical Sky Beauty???

| Alright guys I got another question 4 ya. I have established a sky through flipping a sphere and scaling it around my level. I have applied some textures and lighting but it seems to still be lacking can any of you guys drop me a few hints or tips?? Here's some of the coding I used ---------------------------------------------------------- ;load a sky Global air = LoadTexture("C:\Game\sky.bmp") Global sky = CreateSphere() PositionEntity sky,0,-95,0 TurnEntity sky,0,0,90 ScaleEntity sky,500,500,500 FlipMesh sky ScaleTexture air,1.5,1.5 EntityTexture sky,air ;the clouds Global cloudy = LoadTexture("C:\Game\clouds.jpg") Global clouds = CreateSphere() PositionEntity clouds,0,-95,0 TurnEntity clouds,0,0,90 ScaleEntity clouds,450,450,450 FlipMesh clouds ScaleTexture cloudy,1.5,1.5 EntityTexture clouds,cloudy EntityAlpha clouds,.40 ;establigh my lighting Global light = CreateLight((1),(sky)) ----------------------------------------------- -Like I said guys any help is appreciated!! |

| I forgot to post that I am slowly turning the entity's using this code: Function Sky() TurnEntity sky,0,.005,0 TurnEntity clouds,.005,0,0 End Function |

| Spheres use a lot of polygons that quite frankly you don't need. Do a search for 'skybox'es and you will see how using a cube is a much easier and faster solution. |
| ||
| Easier, yes, faster, not really. |
| ||
| Thanks but could you be a little more specific as to where to search for skyboxes? |
| ||
| Don't you need to make sky boxes/spheres 'fullbright' to stop them revealing their geometry? I dunno - never used one myself. :) |
| ||
| What does fullbright mean exactly?? I am still pretty new to the 3-d scene |

| EntityFx entity,1 |

| Fullbright means that all the triangles are drawn without any regards to lighting - they're all fully lit. Try it with an untextured primitive such as a cube and you won't be able to see which side is which because they'll all be the same exact colour and brightness. |

| Psionic used to have some free skyboxes to download, but they aren't available anymore. Pity. The actual sky textures are easy enough to generate (below is a tutorial on how to create the images using Terragen,) but his samples also had code. http://developer.valvesoftware.com/wiki/Creating_a_2D_skybox_with_Terragen |
| ||
| There's a function to generate a skybox in the Castle Demo. Some generously donated replacement textures can be found here. |

| Check this tutorial (.zips in the end are broken though): http://www.blitzcoder.com/cgi-bin/articles/show_article.pl?f=gametracer04092002.html |

| would this work as well?? .. create a skybox w/ mountain terrain but w/ no sky (instead apply a color used for masking/alpha) and then create a skybox/sphere behind that that you could then rotate. that way you could have a nice rotating sky, but w/out ur mountains rotating as well. i'd try this out myself right now, but i'm at work.. it'll have to wait til i get home. |

| Yeah, you can do similar with water (especially useful as static waves look daft). |
