Recreating "Cloud" effect from Flash videos

I've been asked to recreate the following video effects in 3D. Can you give me any advice on how best to approach this with Blend4Web? Thank you!

Well, everything here can be done with planes and math :)

First - billboard plane or a sphere like I showed you earlier (something about spheres inside spheres), second - animated billboard planes, third - sphere and/or plane billboard, too :) Just play with masks and colors

Thanks! I have a general idea how to do this, but its always good to get Blend4Web specifics.

Also maybe try to use texture masks - for "cloudlike" things

I may as well throw this in - I don't suppose image textures can be animated, like maybe slowly fading between two images over and over? I have an idea of something else I wanted to try…

I meant using image to make those fuzzy borders :) But yes, this can help, too

Try this, maybe: time -> multiply(speed control) -> sine -> multiply(0.5) -> add(0.5) -> mix Factor (textures)

Add and multiply in the end are for the correct work of sine (sine by itself is in -1,1 and we need it to work in 0,1 - so we must shrink it to -0.5, 0.5 and mode it upwards - to 0,1)

Thanks! This should be interesting

OK, originally I was going to ask what "mix Factor (texture)" was, not seeing a matching node, but it's OK, because I figured out how to convert values back and forth so I could use the "mix Color" node instead! It worked beautifully I will link the result of my project in a bit…

As promised, my "Chakra Man", complete with shimmering colored 2D orbs that face the viewer! Thanks yet again for the help, couldn't have done this without you!
