I have hi res Earth texture map :
color = 8k x 4k (8192 x 4096 pixels)
bump = 8k x 4k
cloud = 8k x 4k
A sphere to make earth surface, and a sphere around to place cloud with transparency.
I render that with 1 distant light and a ramp texture to have a little backlight or fresnel.
In the animation, the camera approach the Earth to see countries.
1 - Is there any custom presets to optimise the scene (display and render) ?
2 - Is there a prefered image format ? (tiff / tga / iff / jpg) ?
3 - on the attribute editor, in the “file” page, filter type, pre filter, prefilter radius, use BOT, disable file load… What do they mean ?
