So far the only drawback with Terrain3D is setting up the textures. I'm fine with it from a technical standpoint but for other its a whole process that they'll have to redo over and over again. Glad that there's the texture setup utility being worked on though.👏

The transition from Godot 3 to Godot 4 has taken more than a year as so many things like terrain and day/night cycle didn't exist, and engine devs made changes that forced us to redo work multiple times. This year we'll be producing more media as we're getting things back to looking good again.

Does the occluder also occlude multimesh objects? I think that's where the largest performance increase will come from (e.g. culling foliage behind a mountain). Reason I ask is that I've had issues with setting up occlusion culling on multimeshes in gd4

@TokisanGames 6 месяцев назад

We just provide Godot with an occluder. The engine is responsible for how it works. All object instances in a multimesh show up in one draw call. So, there is no option to cull part of the multimesh. It's all or nothing. If that's what you want then look at your MMI's AABB, extra_cull_margin, visibility ranges, and ignore_occlusion_culling.

@michaeljburt 6 месяцев назад

Gotcha, yeah that's what I thought. There's also a technique to reduce the visible instance count of the multimesh based on distance from the camera (but that might look bad for games with an aerial component)@@TokisanGames

Use Zylann's voxel tools for a voxel terrain. This is height map only. Procedural generation means terrain created by code. We have a demo showing how to create a heightmap from a noise generator and loading that into the terrain via code at startup.

@firerunnew 5 месяцев назад

How high can the terrain be if we make the ocean Subnautica style? Could the landscape be as huge and endless as in MTerrain?

@TokisanGames 5 месяцев назад

The current max is 16k x 16k with potential for more in the future, and height range is whatever fits in a 32-bit float. Around a few 10ks away from the camera and single floating point precision breaks down though, so for very large terrains you'll need to build Godot, the release templates, and Terrain3D with double precision.

im not understanding how to make the navigation im making a survival game and i want animals to use the terrain but then i need the whole world to have a nav when i try and paint the whole world (4 clunks) in the "nav paint" it does not load a nav but when i use less "nav paint" it generates a nav CAN YOU HELP ME

@TokisanGames 6 месяцев назад

Come to discord for support. Using the navigation server is complex and you need to read all of our documentation on it, and much of Godot's documentation. Our docs specifically tell you to create multiple regions if the nav area gets too big. If you need the whole world navigable, you probably don't need a navigation mesh, or you just need to bake an area around the player, which our code generated demo does. The Godot docs will help you understand how best to use the nav system.

@oomegator 5 месяцев назад

Is there a way to increase the texture resolution? As default it seems super low when using sensible measurements. Only "solution" Ive found is to sculpt the terrain at a massive scale and then scale the assets Ive made using real life measurements at to a huge scale aswell. Making a dirt road that is 2 meters wide with default values looks super blocky.

@TokisanGames 5 месяцев назад

Texture resolutions are entirely up to whatever you put in. The demo has 1k textures. In Out of the Ashes, we're using 2k. Max is 16-32k depending on your card. Each texture slot has its own separate UV scale for your control. You don't want to scale up your game as you'll screw with physics bodies and animations. Keep everything at real units. If you want to increase the mesh resolution, v0.9.1-dev already has a vertex_spacing setting.

@oomegator 5 месяцев назад

I see, the textures themselves look good (using 2k) but the way they blend together is super blocky at lower scales. Maybe the vertex_spacing setting will make it blend smoother? Any ETA for when v0.9.1 will be released to the masses?

@TokisanGames 5 месяцев назад

@@oomegator You might have something wrong with your texture setup, like no height textures, or non-recommended painting technique, or replaced the noise texture. Blocky blending hasn't been an issue for many months. I showed how to do it in this video. We have over 20 textures in OOTA and have no issue with blending or texture scaling. Next version will come out within a week, but vertex scaling won't fix poor painting technique or messed up textures. Discord is better for support.

You can increase the strength of most settings beyond the slider max. However, you cannot decrease it so when you need subtlety you want the lower end of the range.
