realflow related scenes
Small tip for coders and TD’s – always check if there is no parent! 
This might be quite obvious but in fact, this is very common mistake.
If you allow user to use bounding box, bounding sphere to control your code or you need to get a position information from object, check if it is not parented! otherwise you will get wrong data!.

I have updated “Send Mail” script for realflow and now it is compatible with RF version 5. Unfortunately as a Unix user I haven’t got much time to test it on Windows machines. I have heard that some of them returns “Home” environment as “None” and that means – plugin will not work. If it does happen to you, please let me know, drop me a line on e-mail or just write your machine/system details in comments. I will try to recreate this problem.
Another one small script, simple as it is but might speed up your work.
This script will only copy transformations from chosen node into another. It was very helpful in my case so maybe it also would for someone else

This script will help You with selecting and passing on particles between two emitters without any collision or link between obiect-emitter.
Commercial made a while ago by Platige Image. I was responsible for fluid simulation done in Realflow, shaders, lightning and rendering done in Houdini.
Of course You can cover up an object with Realflow particles by using “Fill_Object” emitter but then You cannot control and randomize particle placement. So I have created this little script that is going to be a part of incoming, bigger script ;]
Also RF have problem with covering polygons (You can see gap on the edges). With higher surface tension, you will only get bigger holes. This script deals with such problems. Area of each polygon is also calculated so it creates more/less particles when needed.
It’s rather quick tip, not script
Normally to target an object, You would have to play with matrix but Realflow have better way.
You can easily define any kind of emitter and target object (it’s better to use Null object that You can parent to anything You want )
Paste script below on “event script editor”, over “onSimulationStep” definition.
Last year I have been working on few fluid scenes for upcoming Polish movie – ‘Magic Tree’ (Magiczne Drzewo) directed by Andrzej Maleszka [POLISH TRAILER]
Here are two scenes created in Realflow4 rendering and compositing done by Lunapark guys.
I’ll post more info and making of videos soon so stay tuned!
I’m posting little, free script to add and control foam on custom wave object (for eg. imported from dreamscape).
This little script will get verticies out of custom object over given Y value, get their velocity and add Particles in that position. I’m using Null object to better visualize Y threshold value.
I have also added random function for little variation when adding particles.
—- UPDATE!!!

I have just uploaded small script that will allow setup SMTP server and will send You an email with attached screenshot when simulation is complete.
Script can be found [HERE]
