Are there any good free alternatives to Scatter addon? Want to make grass + flowers without doing it all myself.
Hi.
Scatter Objects addon, it is included within blender. You must enable it.
Thanks but a little too basic.
Hi @espr3ss0
there’s a free early version available
You can achieve triple clusters really easily
added a random range option in the custom slot editor, so that the same custom scattering operator could give different result because of size and offset randomisation.
i’ll try to do more range randomisation tomorrow ? what kind of parameters would you like to see ? more would be killer no ? Shall i work on other procedural texture ? right now the only possibility is the cloud texture.

Does anybody know if I purchased the Addon I get free upgrades, or is it just a one time thing?
Yes, you get all updates for free
Cool thank u.
