moving trees/grass
i have a few questions to make something work
looking at xfrog
is xfrog just the modeling plug, with no plant library shipping with it? the xfrog plant dvd’s, is that where you get more preset plants? we were looking at their page, and the blooming flower. did that have to be built by hand?
the reason i ask is we have a quick project that needs us to get these models in place, and ideally have a couple of trees moving slightly in the breeze, long grass in the breeze, and maybe a flower or two blooming. these can all be seperate, we are doing sort of a compopsite world in AE.
we also have a friend that has some poly model trees. would we be able to apply some dynamics – ie, wind, to these objects for natural motion.
from what it looks like the sample tree from xfrog plants, -sweet birch – is a poly model. is that the case with all of them. sorry to be looking for presets but we have so much else to worry about as well.
also with grass – (hair) do i just create a wind object and drag it into forces, or do i need a dynamics tag on the hair object
thanks

[espinoza] “is xfrog just the modeling plug, with no plant library shipping with it?”
No, it’s fully animatable (growth, wind, enthropy etc.) There are 20 or 30 models/ setups shipping with it, I believe, but what you need may not be in it.
[espinoza] “the xfrog plant dvd’s, is that where you get more preset plants?”
Yes
[espinoza] “did that have to be built by hand?”
Parameter animation in the plugin itself.
[espinoza] “we also have a friend that has some poly model trees. would we be able to apply some dynamics – ie, wind, to these objects for natural motion.”
Ditch it. Plant’s have varying stiffness based on the splitting angles of branches and surface areaas of leaves and branches. It’s gonna look like crap or cost you massive work to get it realistic (creating weightmaps or limiting deformer influences). C4D’s Dynamics won’t help you at all.

[espinoza] “also with grass – (hair) do i just create a wind object and drag it into forces, or do i need a dynamics tag on the hair object”
Dragging the forces into the list shoudl suffice.

but youre saying xfrog would likely be able to react to wind?
also, we downloaded the demo, it seems to only be able to build, it doesnt come with any textures or plant models. this is a not for profit job, but to have at their models that ship with xfrog, are we going to have to buy the full thing?

It’s fake wind. You animate the orientation of the branches via a Wind parameter.

Yes, you have to buy them or find some examples by users on the web.
