@Alucard : I don’t seem to have this problem. Maybe it is because I’m using TGA rectangular textures, with sphere mapping option (as opposed to default mapping like it seems in the tutorial)
Edit : just checked again, I don’t think I have the problem you described. My textures are made with gimp, tga no compression, no alpha channel on the surface, scaled down to 4096x2048, mirrored vertically and horizontally, sphere mode in ms3d.
@Timmy : I’m using TGA 4096*2048 textures because after testing with dds (square) and tga, tga finally looks better (50% superior resolution, and my mercator texture is less ‘stetched’ on the poles with rectangular tga). On a side note, I don’t have a problem with tga textures filesizes, as my mod is not meant to become largely public.
@Silent : Thanks for the advice, this one was the first working version, I plan to make tests with other settings on the clouds. Using different models for the different layers allows me to apply different effect on each layer, it was the point.
I would like to also make the surface a little more reflective and the clouds diffuse the light of the cities glowmap behind it.
I will try with 3ds.
About this, what is the difference between cmp and 3ds ? I note cmp are often being used in models and 3ds are being used for icons and small solars, but why ?
Edit : btw, I’m using these nasa maps for my textures. Maybe it will be useful for someone.
Edit #2 : a wild idea… Is it possible to use bumpmaps in FL ? And if yes, is it possible to use bumpmap + glowmap on the same model ? I just found a very good earth bumpmap…
Edit #3 : using my technique I notice something strange : I applied different spinning speeds to the different layers, but the surface is the only one which keeps spinning after a while. I already changed the spinning offsets, and it resolved my ‘single model planet’ spin issue (stopped after a few seconds).
