Don't you think it would be interesting to consider the creation of a new procedural terrain generation plugin on 3ds Max? It is typically a very complementary tool to yours : knowing that scattering tools are improving in the engines, they are taking shares on Forest Pro (Chaos Scatter). I think it would be a good additional asset that would complement and work in synergy with your software suite.
In bulk, the software present in the landscape is either incomplete or abandoned:
- SplineLand, the most accurate with really smart retopology tool but development abandoned years ago, buggy
- TerrainAxe, accurate but requires a lot of manual manipulations to get it right, not sure if you can give precise level points. No idea how it will feel in use
- CityScape, too "rough" when you have precise levels to represent, it's more for large scale urban and its zoning system seems well thought out
Start again from the SplineLand spirit with the retopology improvements integrated to max these last years + zoning synergy like "CityScpae" with Forest and RailClone in support. It would be a dream
When SplineLand crashes too often, I cobble together a manual system with splines, projection modifiers and the retopology + terrain tool. But it's not as efficient.
If anyone has an efficient plugin that I missed, the reference is welcome.
