What Blender truly needs is a proper tool for instancing and scattering objects. This looks just like a random object painter tool. There are already dozen of ways to do this in Blender, but there is not a single way to for example scatter 10 000 high poly trees along with 20 000 000 high poly grass patches. That's why you don't see pretty much any large scale environments ever done in Blender.

What I would like this to turn into is something like ForestPack. A tool where you can scatter large amount of high poly instances, while having them represented in the viewport as low poly boxes or sparse point cloud, and be able to draw only small % of instances in the viewport but render them all. Currently, even particle system instancing fails at that. This would actually allow Blender users to finally create large scale environments and terrains. Something Blender has been extremely weak at so far.

Looks good. Where can i download the zip file or do i have to download the raw file. I have download the raw file and saved with .py extension. I have installed in 2.79b version but it did not installed. Is that only for 2.8 or where can i download the zip file or the complete addon. Thanks

This addon currently depends on an incomplete API, so unfortunately you can't easily test it atm.

I implemented the suggested changes.

Pythons random functions are designed to be used in the case when you want to set a seed once and then get many random numbers.
Therefor setting the seed is relatively slow (resetting it for every new random number is not an object).
However this is exactly what I want because it this way I have much more control about how seeds propagate through the functions. One of the benefits in this specific scenario is that increasing the "density" only adds new objects but does not alter the matrices of already visible objects. I found that to be a desirable property.

So instead of using normal random number generator I use this function which basically generates a hash for every integer. I found this specific function to work very well; It is the main source of randomness in Animation Nodes.

@Jacques Lucke (JacquesLucke) this is an amazing scatter tool! For total usefulness, how do you see any option to make some grid patterns, like hex, quad, radial, and some offsets? useful for hardsurfaces, city buildings and so.

Totally support this, a few patterns could be a very good addition to this :)

That will be awesome!!

Any news on the state of this tool? Is it ready to be used in 2.8? we are testing different options for scatteting large amounts of objects in gigantic environments and I'd love to test this under EEVEE to see how it can hope with high poly assets.
