creating mist & clouds

[haro41]

i came across this image in the image folder and i was wondering how to make something like this. I assumed it was made with some sort of photoshop filter.
im trying to make one to use with the particle system.

Just draw it with a stylus, or use a mouse, lay down some brush strokes and start using the blur tool.

I don't think it would be that hard.

no its not i was just wondering if there was a specific tool or filter to do this. my attempt doesnt come out quite like i wanted but i guess it will do.

I just doodled this up, feel free to use it if it's of any use (used my wacom tablet).

can you export it as a 32bit image with alpha trans set

I didn't save the file other than that JPG, perhaps later I can make you another if you so wish :P

All you really need to do is just take the airbrush and set the color to pure white, and then you adjust the transparency of the brush to a really low setting, and start going back and forth over a black area. You just keep applying pressure to the area you want the whitest.

To make it even less brushed looking, you can use the smear/smudge/whatever tool to sort of mush it around the way you want it.

If you want to do it with 32 bit "PNG Exporter> Alpha" than just create the cloud image on a secondairy layer and use smudge tool. But I have no idea how the particle engine does light effects on 32 bit images yet, should probely work the same as a image with a black background.

If your realy lazy, than use psp's custom cloud tubes and modify those (but thats cheap..)

That was my cloud gfx hehe. I made it in photoimpact. It was an inbuild effect =P
/lazy

actually it doesnt matter if you use it in the particle engine or not. I usually end up using mode 1 (transparency) in light effects. but its all in what your trying to do.

as for the picture tubes. ive been looking around but havent found any really good sites. for version 7 anyway. cloud tube wasnt built in.

That's funny, because I was thinking (didn't look it up), "Hmmm how would you generate a landscape?"

I figured you would use fluctiating random point which have life cutoffs so it could either generate a nice arch or cut it off part way and begin another. The top of the arch (or bottome) would be defined randomly and the little script would just generate.

ummm.. you lost me half way in the second sentince >.>!

But the Perlin Noise functions are quite handy I guess... I'm gonne apply them on my boring 3d textures to spice them up a bit.
