Always the same... / 3d people on a surface
« on: September 25, 2018, 02:56:25 PM »
Hi,

I'm trying to scattering 3d people on a surface.The problem is that, it's always the 3/4 same items that appears.
I've tried the random seed, to random probability, things like that..nothing. Some people are stronger than others... ;-)
Any ideas will be appreciated.
Many thanks
Regards
See attached (the bordeaux one for example..)

I just did a "small" test and scattered 42 rocks 42000 times- every rock was scattered ~1000 times. Randomization seem to work fine.

You can lower objects probability manually- that is what a number next to name indicates. They all are the same by default (100). Feel free to lower probability of those stronger people.

Thanks for trying it.
I've tryed to change the probability  of the "stronger"one. To put all to one, to random prob.  No way, it's another rooster that came out :)
I don't understand this "selection"
Problem with the painted surface maybe ..?

For a better result, I even dreamed to have just one of each.

It's not possible to avoid than sometimes same items are scattered together, it's the nature of the randomize process.
Although this issue is more noticeable with people than vegetation.

Other alternative would be to randomize the cloth using Forest Color. If there are not several textures available, you can tint the Diffuse or other texture slots.
It may help to differentiate items which are using the same model.

THank you.
nice tip the forest color. Have to try.
I was wondering if it's possible to scatter just one piece of each people on a surface with Railclone..maybe..?
Thanks again for the great support.

Hi
Actually yes it is possible to do some kind of scattering with RailClone

Wire all Your items to Sequence operator,
Add one more default input to stop from repeating:


Adjust padding settings so all items sits in more or less one place and add randomization to translate them to random positions:
         

Unfortunately You can't use collision detection, but items are scattered only once:
