Newbye here. In the industry lingo, what is the best way to indicate the objects covering the ground (trees, rocks, ...)? Is
I would say
game assets is definitely not specific enough. Everything in your game is an asset — the terrain itself, the shaders and textures it uses, every JSON or XML data file.
Similarly, I'd argue
props is also too broad. A chair or a sword could reasonably be called "props" too, but they're not scattered terrain items like you're describing.
(Though to be fair, maybe your game has no chairs or swords or any other variety of prop, and so in this case it's OK to use a broad term)
If your game has different biomes that need to scatter a different mix of grass and trees and rocks, I'd be tempted to call these "biome objects" — but that might be needlessly complex if you don't have multiple biomes.
Some other options: (none of these are particularly standard, just looking for phrases that describe your use case)
- Terrain Dressing
- Ground Cover
