    A couple of basic questions about TP (C4D R13)

    How do I split a group into a couple of subgroups, also how to control the proportional split?

    Secondly is there a way of ‘containing’ the extent of wind and/or gravity by putting it in a box or something to limit its influence?

    Thanks

    The TP Group Change preset has the basics but because it’s trying to be able to do a lot it’s more complex looking than is actually necessary for a basic group change. As to a proportional split, what kind? Based on some factor or a random split? (for which the Random node would probably be the way)

    Containing wind and gravity – with the TP presets Spherical Wind and Gravity there is a falloff option – it is possible to use the same presets and modify it (the PGravity node inside the preset xpresso) to planar but still use the same spherical falloff set in the preset.
    If you want different shape falloffs I suspect it’s possible to use the MoGraph xpresso Falloff node to use the full range of shapes. Shown here https://lesterbanks.com/2011/09/creating-mograph-clones-in-cinema-4d-with-falling-off-deformers/ Lester Banks references a Robert Leger tutorial which unfortunately isn’t up anymore. Should be possible to do with just the example Lester starts with before he moves on to the mograph uses for the falloff and a PerAnders script also referenced.
    Definitely, just tried it and it works. It can also be used to change groups if a particle gets inside a falloff (as a simple example) 11205_tpfalloffnode.c4d.zip

    Thanks a lot Brian for the guidance. I’ll give it all a try however I always found Mograph totally intimidating so will be taking it very slowly!

    All the best

    All good really, for working with TP you don’t need mograph only the falloff node which, when you try and find it in xpresso, is in the mograph section when you right click to add a new node.
