Hi, I've been placing some world elements like grass, stones etc. in WE and I came up with an idea - it would be good to restrict angle of terrain that object can be placed on, like it is with textures It would save a lot of work during placing eg. grass on uneven terrain, if we want it to grow only on even places, or rocks on slopes.

hmm.. i somehow always wondered but never really tested something similar.. like in CryEngine you can assign elevation and angle ranges to materials. then when painting terrain it would automatically assign predefined materials to appropriate areas. Then very little effort is needed to paint terrain, because steep slopes would get rocky materials, while flat areas would be covered in grass.

what i would suggest is a little bit more advanced:
What about multimaterial brushers?
How it would work:
User would create multimaterial brush, name it maybe.
User would add material N, assign a certain parameters that have to be matched in order for material to be used when painting. Those parameters could be min/max terrain angle, elevation.
User would have to enjoy using custom brush then )

That should be a significant addition.

@Hemi: cool you brought this up, somehow i never thought of suggesting this for some reason

This is a good idea. It might take a little more planning up front but would save a lot of time in the end. With the custom brushes you could easily paint different biomes/climates just by switching brushes.

added to the roadmap!

I think other good idea would be individual density for each object in object brush. When I am painting grass, I use some base types of grass + flowers and flowers have far lower density.

If you change the speed slider it basically acts like a density parameter.

I know, but i am not able to set it for each mesh individually.

Gotcha. Did not catch that you wanted variable density for different object types in a list. Seems like a good feature.
