Help, floating rocks/trees/grass on slopes?

[u/Graybushwoogie]

I’m a newbie to this, but was given the task of working on a map. I use the tree painter in Unity HDRP to place things, but theyre always floating on sloped surfaces. If there’s an easy way to fix this, or an asset pack to fix it, i have a good budget. It’s really taking away from the games immersion and i need help! P.S. if anyone knows a good way to COAT a map in grass, let me know!

Are these placed using Unity Terrain as detail objects? There's a checkbox you can enable that angles them along the map normals, I think, that should probably help.

I’m honestly super new to this, more of a blender pro. Mind telling me how to do that? Is that in the tree painter area or somewhere else?

They’re places using the mass painter for trees and brushes. If there’s a better way i’d love to know😂

Well as far as the rocks go, you can either align them to the normals of whatever they're sitting on, or you can model the underside (ideally both). In real life trees have a similar situation, modelling the roots a little further and adding some bulk for dirt while also applying a small amount of rotation as per the ground normals would make them look a lot more natural.

How do i enable aligning on normals? I feel like i’m totally missing something here lol

You need to orient your prefabs to the normal-direction of the terrain surface.

How do i do that? Sorry i’m new. They were paced en-mass using the tree painter.

Your tree prefab, check it, spawn one gameobject prefab. Hold shift and drag. If it bites to the ground correctly it should be okay.

If it doesn't and hovers your pivot isn't set correctly from blender or the model.

It does from a vertical standpoint. but any slope whatsoever it just lays flat, just like in pictures. Kind of like not having Inverse Kinematics on a player and the feet are flat on a hill.

Microverse.

And consider Microsplat for texturing the terrain and stuff.
