Scattering tool a la Hammer 2014 ?

[motorsep]

So Valve released Source 2 with new Hammer unofficially:

 

 

Would it be hard to implement such scattering tool like seen in the video for DR?

This video is about Warcraft.

Painting landscape like that is very cool, but I've no idea how it could be implemented. Scattering of models through a pre-defined area (such as a collection of brushes) could be done by a python script. Which can use the Floor Selection command to settle the models (plus SEED is already available to do it at run time rather than design time).

Well, I am not talking about making terrains. I am talking about selecting entities (or models), setting randomness and parameters, and "painting" them over brushes/meshes in DR. SEED is only for TDM, and it's procedural thing - designer has no control over placement and other factors.

 

I am thinking the core issue is that DR would need a new way of navigating CAM view. Like pressing and holding Alt would allow navigating it, and otherwise you can edit your scene while in CAM view.

So you have a grid and a random number generator. A size adjustment for the size of the grid and the density of the placement. Sounds doable on flat surfaces. On non-flat surfaces you have to map the placement grid to a mesh and then rotate the models according to the normal vector of each triangle on the mesh.

eg:

You can't adjust size on models in idTech 4, thus you can't scale it in DR. So size is a constant. Rotations and location are the only variables, and grouping, and whether to follow normal vector, or stay vertical/horizontal with some deviation. With random factor on all these variables.

So is it something doable (without too much troubles) ?
