Talk about anything

Pixophir

Megalomaniak Will yours?

Definitely not in the first version.

Megalomaniak production ready

That'll be next year, I can say. I also need people's feedback. It is the first time I intend to do software for someone else to use. Do I need a full plate ?

Megalomaniak

Pixophir For testing and feedback I'm sure it'll be fine. But caves will likely come up as one of the first requests, if from nobody else then me. 😆

Megalomaniak

Megalomaniak Note that all thats really required for caves support is the ability to have holes placed in the terrain, caves themselves could be kitbashed from some rock models or modeled as per need in a DCC such as blender.

For wicher 3 IIRC CDPR achieved it via discard with an assigned portion of the terrain just made invisible and the collision in that part just disabled. The cave then was kitbashed with perhaps segments of the floor just custom modeled. IIRC, of course. They gave a presentation at GDC I think, so a pdf file of the accompanying slides can be found online I think.

edit: scratch that, in the presentation they state outright that can't just discard for the holes because it disables early-z and hi-z.

Terrain with caves... yeah, count me in on that. I would love to build a game similar to The Infected, and that had a good amount of caves- enough to get people lost, even.

Tomcat

Megalomaniak There is scatter which can cover the same need tho.

It's a great plugin, I'm keeping an eye on it. 👍️ But it doesn't generate the vegetation itself — it just arranges it.

But for a flora/vegetation plugin to become necessary we would first have to solve a more foundational/formative issue first: a honest to god good/production ready terrain system.

A terrain generator is desirable, but not necessary. One can take a surface made manually.

There is Heightmap terrain, what's wrong with it?

That's all well and good but most heightfield implementations don't support basic things such as cutouts for caves for an example

What to implement automatic generation of caves need to take into account erosion… Well not everyone has supercomputers yet.

Simulating Erosion: An experiment

Terrain generated with algorithm 2. Blue line is a raindrop. Colors represent hardness.

Megalomaniak

Tomcat There is Heightmap terrain, what's wrong with it?

In my experience very unstable and very basic. Though admittedly last time I used Zylanns heightmap terrain was in godot 2. But I've also seen others complain that it/their projects break when updating godot from say 3.1 to 3.2 or such, which is where having access to say a commercial support service from the plugin author would be nice to have and I'd consider that actually another requirement for it to be considered 'production ready'.

Megalomaniak

Tomcat Yes, voxel terrain solves the cave issue passively by it's very voxel nature however it can have it's own undesireables, such as lack of artistic control over it. Obviously depends on the game and it's design.

Megalomaniak

My personal ultimate wet dream would essentially be to have something like world machine inside of godot procedurally generating dynamic(in editor of course, final export build would be static) terrain chunks according to a visual graph that can then be further modified/influenced by child nodes such as curve guides for projected roads and bridges that in turn also regenerate the parent terrain chunk to flatten the terrain where needed to accommodate the road or to flatten the segment of vertices underneath the bridge foundations and pillars or underneath building foundations etc.

But that's a bigly/huge ask. So I'll just keep pipedreaming.

Tomcat

Megalomaniak Well, that's a pretty modest wish… I would like the relief to change, e.g. from overflowing or drying up of rivers…

Megalomaniak

Tomcat That can probably be done with a custom shader on the terrain.

Pixophir

Yeah, yeah, yeah. Can all be done. Maybe not yet with voxel terrain an in realtime, but with 2.5 D and real world sensor data (I use SRTM 90m data for testing), or good old fractals (no surprises, you know what its like around the next bend, yawn :-)), or noise. A lot can be done with noise, actually ! (libnoise). But one really needs parallel computing power for high levels of detail.

Megalomaniak

Pixophir See here:

Tomcat

Megalomaniak Apparently so. In a small way terrain changes can probably be done with shaders.

Pixophir

Cool. I also have modelling actual physical processes in mind. Like drainage systems, tectonic features, erosion structures. But first the LOD renderer. I'm in grave danger of being distracted, again :-)

I missed a chunk so necroing a little:

Isn't W4 to Godot what Canonical is to Ubuntu? If so I don't see what the issue is, if anything it just ensures Godot's development and support is stronger than ever into the future. Thinking about it, I think W4 is even more hands off than this and only appears to exist to counter a very real issue to Godot's adoption (console support) in the only way possible.
Plugin licensing is already per plugin and down to the discretion of the person who wrote it, so don't see how this is remotely related. The promotion of paid plugins may be contentious, but in my view is positive in it provides the community more/'better' options as people are attracted to money, even if you yourself don't want to pay. Plenty FOSS projects wouldn't be where they are today without underlying enterprise support agreements/paid extras keeping the lights on and plenty of people will still release free/MIT plugins simply because (Still see this in Blender community).
Terrain gen with caves can be achieved with marching cubes. Is one of my many side projects, but nothing like complete.
I sort of toyed around with river/erosion idea ages ago, and it wasn't fast. Compute shaders in 4.X can't come sooner ^^
Painting vegetation got a serious bump recently, this plugin is as good as it looks and pretty much just works:

It's a good plugin, but it doesn't create vegetation, it only places ready-made models.

So you guys know, it's a full moon tonight. You guys like to do anything special?

Well, I'm a werewolf, so I'll probably go out and eat some people...

some_lame_kid

cybereality do you eat more under a supermoon?

No, but I will restrict my diet to vegans, and people that eat organic food.

cybereality Where you live, I'm sure that won't be hard.
