    Amospheric question

    So, I'm working on a Culture orbital, and I wanna film from ground level and up and away to space

    Any tip on how to create the atmosphere? A transparent gradient? Native fog option, blue and exclude everything besides the atmosphere boxes?

    - Never done that sort of thing before, so not sure how to attack the issue, so if anyone could point me in the right direction (and preferable using LWs native features)

    Using LW 11 by the way

    That is pity.. Because newer LWs have very nice cloud features..

    ...not clouds - got that covered - the atmosphere itself; the blue stuff

    like Sensei says, you can use Skytracer, and use the atmosphere only.
    not super, but works Ok.

    adding fog can be done, but you won't get render quality like in LW2020.

    i guess tweaks can be done tho' in post.

    but do check Brian's trick >

    It may not meet your needs, but an old-school approach to an atmosphere gradient (e.g. around a planet) is to combine two Edge Transparency shaders, one with its mode set to Opaque and the other with mode set to Transparent. By adjusting the Edge Threshold on them, you can get an opaque gradient where the atmosphere is thickest.

    A quick sample LW11 scene is attached. It uses a Puffy Clouds texture on the surface of the ring, has a transparent Atmosphere layer for the Edge Transparency shaders, and a particle emitter to produce Hypervoxels to obscure the transition from the clear to opaque portions of the atmosphere.
