hi,

i want to scatter a forest on a plane with 5 different random mxs trees.
do i have to create 5 scatter definitions now (thought they should have the same parameters) or is there an easy way to scatter these 5 trees with only one scattter definition ?

[mojo]

is there also a possibiblity to avoid that the different scattered trees are overlapping each other ?

[seghier]

use random seed for each scatter and to avoid overlapping use density map ; try to get the best result

Currently the scatter modifier takes one object, or one MXS Reference. I guess you could in that reference place several trees, and it would scatter each reference but I think that would quickly become too repetitive looking.

So for now you do need 5 different scatter objects.
There is no collision detection at the moment.

(seghier, it's nice that you are so eager to give advice to people, but please make sure first you really understand what it is they are asking )

thanks but you must understand my response
he ask that 5 scatter have the same parameters and i reply that he must use random seed and use density map ( 5 differents maps created in photoshop fo ex) and use them to avoid overlapping ; that what i did before i see his thread

[Mihai]

He asked if it's necessary to actually create 5 different scatter modifiers, if they all would practically have the same settings. Not about random seed for each of his 5 modifiers.

[seghier]

he say already the solution and than ask
do i have to create 5 scatter definitions now (thought they should have the same parameters)

[mojo]

thanks for your answers.

so i put this one on my personal wish list. I know this possibility from Vue, where you can select different objects to a list (with a percentage definition) and paint them onto a surface...

best regards,
mojo

so only one object and no collision control? Is there any chance to get this improved in NEAR future?
I think NL knows how tools like Multiscatter or ForestPack work today...
(a polygonal controlled distribution would also be helpful)

use random seed for each scatter and to avoid overlapping use density map ; try to get the best result

How should this work? By painting 5 different distribution maps without overlapping?!? Not really practical.

try it . it's possible
for example in sketchbook create one black layer
erase part from it and duplicate the result
erase other part from the new layer and duplicate it. than erase new part from the third layer ( you can use other methods )
every layer is a density map and you have seed option to get the best result

[numerobis]

sure, why should it be NOT possible...?
but it is far from an quick, easy to use and direct adjustable solution... it is a workaround.

[seghier]

its quick
what you do for the density map of the grass ? is the same thing draw your own map to get what you want
and you can mask any part from scatter
