Gardener, from the BM description, is for Bushes, Hedges & Shrubs.
When I looked at Grassblade, I ended up going with Vegetation. To me, something looks off in the Grassblade results, maybe it’s the saturation, or the overall materials, but the look doesn’t feel natural to me.
Vegetation is good, though if you like to customize the path of your assets like I do, you’ll be in trouble with it: the assets need to live in Blender’s add-ons folder (I think it’s almost 12gb of data).
Another minor issue I have with Vegetation is that, every time you add a new asset to your scene, the selection remains on your last selected object. So, I always end up moving the wrong asset. Nothing too crazy, but a little annoying.
The third problem is that when you add an asset to the scene, it’s not organized in categories.
Then, and this is a deal-breaker for me, the assets are not linked, but appended, so you end up with gigabytes of scene files (unless I missed something).
I reached out to the developer about the issues, he said they would look into them, though I was the first asking about the collections. I didn’t hear back since then. So, I tend to avoid Vegetation, which sucks because the quality is good, and it’s not a cheap add-on which now sits unused on my hard-drive.
Then I bought Botaniq: well organized (none of the above-mentioned issues), and in case of problems, there’s a pretty active Discord channel.
So, my personal choice when it comes to vegetation are: Scatter, to scatter stuff around, nothing gives you more power than that, and Botaniq when I need extra elements. Botaniq also has a great choice of grass, which seems to be your priority.
About the “tricks”, Botaniq has some features, though not as advanced as Scatter.
But its options can already come in handy:
And then you have this in Scatter
If the price is too steep for now, you can wait for a BM sale, or go with Scatter, and add another vegetation add-on later.
BagaPie should be cheaper, and gives you some options for the display tricks you’re looking for.
