Chaos Corona for 3ds Max > [Max] Daily Builds
Clouds playground!
maru:
Here is a trick:
Set up your scene with the animation you wish (e.g. animated clouds, some animated geometry - whatever you wish).
Do not enable motion blur.
Render your image as a sequence with pass limit set to 1 (it could be more if you wish to get better overall quality) and save each frame in CXR format.
Then open CIE, use the "merge" option in CIE, and pick your CXR frames.
You should get something similar to motion blur as the frames will be simply stacked on each other.
You can also use a different format and stack them in other software.
To get a different motion blur curve, you would probably have to adjust the shape of the animation curves in the 3ds Max curve editor.

However we're working on an island project right now where it's typical to see distant clouds on the horizon (pink at sunset, etc) but NO clouds above you. It's just a certain 'look' we're after. Is that possible with the corona sky clouds? I've modified the seed endlessly, and dropped the height limit to as low as I can but just can't quite seem to create a 'horizon bias.'
Thanks!

try doing cloudy + cloudless CoronaSky and blending them with some angle-based falloff map... maybe it will work reasonably...

If you play with the improved model altitude and cloud position altitude you can get some ok results. The biggest problem is the gradient at the horizon line that fades out the clouds, would be nice to be able to reduce it. Would make it look cleaner and further in the distance like the attached photo.

Not sure if this has been mentioned but the brightness intensity of the clouds doesn't scale with the sun multiplier.
So if the sun is on, the clouds go really bright, if you reduce the sun multiplier to say 0.1, the clouds brightness doesn't change. They only change when you turn the sun off completely.

Hey,
Which Corona version?
