Tried to fiind some examples code in the C++ SDK as suggested
Impossible to find - apart from definitions of  FallOff in SDK

Anyone find anything at all on this subject that I can see working pls

RandomFalloff C++ example is located at "CINEMA 4D\plugins\cinema4dsdk\source\falloff\randomfalloff.cpp".
I converted it to Python. It's very simple but if you're interested please email [email protected] and I'll send you the plugin files.

Sorry Yannick

I misunderstood - I thought you meant there was an example in the documentation

Much appreciated - will send email

@Yannick Why do we have to send an email to see this example?
@deepshade currently working on an example, you can get it in a few hours.

Cheers, Niklas

|Edit: Ehm, random-falloff example, nice and pretty, but nowhere is documented how I should calculate the relations to actual point I should modify, somewhat more complex example, for example spherical falloff, would be much more helpful, because the random isn't actually helpful at all.  The C++ documentation doesn't say anything about how to calculate the correct point to sample relative to the effector.

Even the most important part is missing ******due to inadequate **documentation , here is an example of a FalloffData plugin, including handles and drawing.

Download Py-FallOff Example_0_1.zip from Mediafire

thanks to everyone

I'm sure some reverse engineering is going to very useful. I was looking to investigate controlling falloff in the python effector - or more accurately falloff using a know object to base the matrix on.
But it all helps fill in the gaps.

I still can't (currently) see how to make this work like the xpresso falloff equivalent.
I'm looking for a bit of 'universal' falloff code (all the current falloff options)  
and attach that to a null.

Side note:
I guess on any project there are going to be gaps. My suggestion would be to aim for at least a single 'working' code example in each 'major' topic.

And get some sort of poll on what areas to put sample code in first
Objects
Points
Polygons
etc

thanks again

Paul

I'd be glad if some guy from Maxon could tell us how to correctly use the FallOffData.Sample method.

Hi Niklas,

I contacted the developers on this.

p vector given to Sample() is the clone local position. To get its global position multiply it by data.mat, the falloff matrix.

Thank you very much, Yannick! Could you put that on "your list" on things to be documented please? As far as I've seen it's missing in the Python as well as in the C++ SDK.

I could do very well with an Falloff example....
Can't get my head around it at all.
My task is to simply use the FallOff for a PyEffector.

Maybe I shouldn't try to do things at 4am and get some sleep instead :).
I'll look into the default PyEffector falloff example and see what I can get out of it.

What I -was- doing was using a PyExpression Tag trying to transfer the
ColorArray from one Cloner to another, that's where I get the error message
that a "falloff must be present".

Then I looked into the mograph.FalloffDataData to see if I could make it work.
But maybe I am misunderstanding what FalloffDataData really is and
it is not meant for the falloff from within a Cloner?

In this particular case I ended up doing the ColorTransfer using a PyEffector,
as I suppose it is the best way of doing it.

Cheers
Lennart
