Using Terrain3D in Godot 4 - Part 2

[@Chevifier]

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.👏

[@yourmajesty9025]

It would be absolutely amazing if you could add your own plant placement system in Terrain3d. Third-party systems are inefficient and inconvenient to use. ❤

[@danyknight9107]

Right now it will convert T3D in a complete Terrain on its own, it is great as right now, but scatterting vegetation is truly needed. Tokisan, thanks for this amazing gift

[@prestonharrison2140]

Agreed! I'm currently using Proton Scatter and while it's great, it feels like a misfit for what I'm trying to achieve.

[@Gdquest]

You did an oustanding work not only on this whole toolkit, but also on this video! This is a really well-thought-out tool, and I can't wait to see what will come next for this project. :)

[@Kafesho]

I've worked with a lot of terrain editor in my game dev life (commercial & in-house ones). This is one of the easiest I've ever had to setup, especially considering the amount of quality features included. All of this for free. Thank you so much for your hard work! Godot users will be forever grateful.

[@TokisanGames]

Thanks for the kind words. Given some of the comments I get, you'd think it's the hardest one. Guess those people haven't tried any other system. Now that we're in the Asset Library, it's a cakewalk.

[@Kafesho]

@@TokisanGames Yeah I can understand the feeling if you're not familiar with the tech. Young game devs are used to easier setup on Unity & UE. Just dropping a few texture.png in the properties, and then you're good to go to edit the terrain. They don't know how it's not optimized for their crazy open-world ideas, or the terrain requirements for it to happen. But if you know, you realize that Unity terrain is the worst terrain tech, and UE terrain requires a lot of setup and actual work on the material (map regions, dual scale, texture blending, noise variations, auto-shader, etc...). From my own experience, you've done way more than other solutions. Most of the work is already done and included, super easy to setup on your plugin. I believe we often get this problem with commercial videos from UE (or quick tutorials for grass shader on youtube). They love to show you that polygon limit doesn't matter anymore with Nanite, or how to get thousands of grass blades, without showing the reality of game dev. Beginners won't question it, but pro game dev will consider build size, number of materials used, shading limitations, etc... Anyway, like most subjects, everybody's got to learn a lot before understanding how much more complicated things are in reality. (I'm doing my best to not get grumpy on it ) Thanks again for sharing your work on terrain. You've done way more than my own capabilities, and I understand how tremendous that task was. I'll be forever grateful for you to share it with us for free. Cheers!

[@Connor_Sherlock]

Terrain3D is the last piece of the puzzle in getting me to switch from unity to godot. The macrovariation and dual scaling add are going to add so much production value for basically zero time investment, love it. If you ever expand on the procedural workflow and add shadergraph-esque visual node based UI it be will everything I could every hope for in a terrain system. 10/10 great work keep it up.

Thanks. Will do. 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.

[@firerunnew]

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]

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.

[@smorty3573]

This tool is incredibly useful and it seems to be rather performant too (as long as one is not using the anti-texture-tiling option). I have one question though: Can one somehow sample the terrain texture using some shader include perhaps? That would be incredibly useful for blending in some rock or building models into the terrain. This way overhangs could be simulated by blending some rock meshes into the terrain by sampeling the terrain to make it look like it's part of the terrain.

[@TokisanGames]

Our implementation of detiling is not expensive. Answered your other questions on github.

[@rahmanlinux9602]

[@smorty3573]

In the video you demonstrate how to create smaller paths. This is great for small areas, but how would one go about creating longer paths? as in, kilometer long ones?

Paint it by hand. This is a hand painting tool. You could also edit the maps by code. If you want a road with a defined texture, use the Godot Road Generator addon.

[@Konclan]

It took me a while to understand that even at 100 strength the spray tool is pretty weak, I thought it was broken and spent an hour trying to figure out why.

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.

[@TokisanGames]

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.

[@TokisanGames]

No, there's already a road plugin for Godot. Won't take much work for it to snap to the ground if it's not already native. We already have a slope tool for sculpting flat, angled ground and paths.

[@kobeguy]

@@TokisanGames Gotcha thanks! I'll have to look into the snap to ground feature for making roads/paths as it would make it a lot easier.

[@vast634]

Why not an option to let the "auto shader" overwrite the manual shaded parts (overwrite blend data). Then turning auto shader off / marking it manual, and the user can alter the auto shaded parts.

[@TokisanGames]

Baking the autoshader is worth considering. The user can already alter the autoshaded parts with settings or manual painting.

[@kfrz]

Maybe I'm completely inept; but I am unable to figure out the GAEA->GODOT workflow for this

[@TokisanGames]

Every commercial tool has the ability to export heightmaps in format we can read directly or that can be manipulated in photoshop/gimp/krita. I searched and instantly found that Gaea can export PNG, Tiff, and EXR up to 16k. Use EXR as our import docs recommend.

[@kfrz]

Thank you, I have no issues with export or format; the issue is the Array object assigned to the panel is totally uneditable; the ONLY workaround I have so far is to import the height data but copy/paste the example 3dTextureSet from the demo project and even then I can only replace a texture, I still cannot add elements to the array. I'll read the code again and try to suss it out. @@TokisanGames

[@TokisanGames]

@@kfrz Come to discord for support. If you can't use the tool as I demonstrated in this video, then you have an installation problem with the plugin or Godot. You might have error messages on your console. You should not be editing the array in the resource, which is read only, but using the texture panel as demonstrated.

[@DarinLawsonHosking]

Quick question you say it does procedural generation can that be Voxel base terrain?

[@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.

[@warsin8641]

tysm love ya!

[@oomegator]

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]

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]

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]

@@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.

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]

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.

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
