godot_heightmap_plugin VS smoothing-addon

Zylann's repo has a v4-compatible branch that was last updated 4 days ago, and there seems to be another one working on this, and another one published a few months ago, plus there are lots of videos out there about doing it in other tools and then just importing the heightmaps / splatmaps in Godot (e.g. from devmar's YT channel).

godot_heightmap_plugin

Back in 3.0 I was using this plugin for heightmap terrain: https://github.com/Zylann/godot_heightmap_plugin

source: https://github.com/Zylann/godot_heightmap_plugin/issues/279

You can create terrain and paint it with the zylann.hterrain plugin. Currently only supports Godot 3.x.

Sweet, how's the tooling to actually make a playable textured level from a heightmap though? In 3.0 I had to rely on Zylann's excellent plugin which was all well and good but I needed to compile it for each platform I wanted to ship on, and editor integration was good but not perfect. Also procedural generation of terrain in-game wasn't practical.

As we know, there's a lack of a node similar to Unreal's Landscape and Unity's Terrain. I believe this hurts Godot more than generally assumed. There is of course Zylann's plugin for 3.x, but I believe an officially supported node for this would be incredibly beneficial. Zylann's plugin will most likely get updated for 4.x eventually, but I personally know people who were shocked to find out that this functionality was not in Godot 4 when it had so many improvements for 3D - and it ended up being the deal breaker that pushed them away.

The one I know is Zylann.hterrain which is gdscript but also not updated for 4.x

I have been tearing my hair out trying to figure out this issue. This problem seems to have come up suddenly, but I'm not sure where I went wrong here. I don't think it's a physics related issue as this plugin (https://github.com/lawnjelly/smoothing-addon/blob/4.x/README.md) doesn't seem to help.

Speaking of smoothness, are there any plans to somehow integrate lawnjelly's excellent smoothing-addon to Godot core? In my opinion pretty much every game needs to use that addon.

I've found that there's an addon for 3.x and 4.x that adds physics interpolation, which is great, but it's clunky to have to introduce another node for every visual physics object, as well as having to rework the scene tree since visuals can no longer be children of their parent physics objects. I've also discovered that it fixes large jitters but not small jitters, which seems like an improvement until you set your max FPS equal to your physics FPS, and realize things still can be SOOO much smoother.

There's a smoothing addon that can help with this issue, in my personal projects I've just been using this since I'm not currently using rigidbodies.

But, you mentioning the sprite moving and not the CharacterBody2D inspired me to dig into my player scene more and found out that the "Smoothing2D" addon I was using was the culprit (https://github.com/lawnjelly/smoothing-addon/issues/31)

The smoothing addon by lawnjelly has a 4.x branch so you can use it: https://github.com/lawnjelly/smoothing-addon/tree/4.x

in 3: enable physics interpolation in editor settings in 4: download lawnjelly smoothing addon for 4.x

4.0 doesn’t offer physics interpolation from what I can tell, at least for 2D. Try this addon, it works for 2D and 3D and I’ve heard plenty of great things
