    I need help. I need to figure out how to make a realistic clouds using 3d studio max or some other compositing software without using a normal modifier or a sphere.

    aye, i'll try to keep it simple dude

    Step 1: For volume clouds to work you must first define the limits of the scene. For the renderer to know when and where
    to stop rendering you must create a backdrop. A booleaned sphere or a box works fine. For my example I will use a booleaned
    sphere.

    Make a hemisphere with a radius of 50 and 16 segments.
    Click on the scale button.
    Scale the sphere down 10% while holding shift. 3dsmax will ask you if you want to clone the object, select copy and click ok.
    Move the inner sphere so it is offset with the outer sphere.

    Step 2: Next boolean the spheres together.
    Select the outer sphere.
    Under geometry pick compound objects.
    Select boolean then pick copy and select the inner hemisphere.
    You now have made a good backdrop.

    Step 3: Set up a camera inside and the sphere.
    Tilt the camera so that it has the inside of the sphere in it's view.
    Select a blue material for the sphere.

    Step 4: In the Render enviroment select add volume fog.
    Select exponential.
    Density 40
    Step size 4
    Max steps 100
    Select fog background
    Select fractal noise.
    Noise threshold high =1
    noise threshold low =.2
    uniformity =0
    levels =6
    size =40
    wind = front
    phase =0
    strength =0

    Select the camera view and render. Be patient because this is very processor intensive. You can add ground and
    whatever else you would like to the scene. These clouds appear to be real without adding any geometry to your scene.
    You can even do a realistic fly through. If you would like to just limit them to a certain place in your scene use an atmoshpereic
    apperatus in the helpers rollout.

    I wish i could explain ya in graphical ways...
    bt i think if u know how to work with max, u'd be able to follow the proceedures;)
    Good luck bruv;)
