Well, just as anyone here, I'm here to learn!

So I had an idea! What about starting a little tips and tricks thread? (Well, little for now, but hoping it will grow!)

So how can you participate in this thread? It's simple!

Just share your tips and tricks on particle flow / krakatoa. These can be tips and tricks you have learnt yourself or from others.

You can make it as detailed as you want (like somekind of tutorial) or just a very quick text-only how-to.

I do encourage you though to post at least somekind of final result screenshot / render!

So I will start this one out for now!

HOW TO CREATE LIGHT IN YOUR PARTICLES (Thanks a LOT to Bobo for explaining this to me!)

QUICKLY RENDERED PREVIEW:

STEP 1) Create a spherical PF source, and an omni light. Place the omni light inside the PF source and link them by using the "Select and Link" Icon (should be topleft in 3Dsmax and look like chains)

STEP 2) Open the PFlow editor and adjust the Speed direction to "Icon center out" and set the speed to about 50

STEP 3) Select the omni light, and set the multiplier to about 0,5. Set the "Decay" type to inverse, and lower the "start" value

STEP 4) create a vortex force and place it around your emitter, and a gravity force, make it spherical and center it.

STEP 5) fiddle around with their settings a bit until you get a bit of a nicer swirl once you animate a few steps.

STEP 6) go back to your omni and make sure the "start" value isn't too big so that it stays about halfway your little swirl (I used around 25 myself)

STEP 7) go to krakatoa and override the color, set it to something you like, and select "force additive mode"

STEP 8) play around with your particle count and density, and enjoy!

So what have we learnt?
---------------------------

Well, the particle animation itself is nothing big, but for those that didn't know yet. THIS is how to create that effect of light in emitters.

Of course you could color your omni-lights and create other cool effects!

For another preview of what you can do with this technique, check out matthias muller's krakatoa video (it's awesome)
