Voxel Plugin

[BinaryScrub]

I'm finding myself in the same boat. I've gone through a few different gravity solutions so far with no luck. Is anyone having any better luck than we are?

[Phyronnaz]

BinaryScrub There's an example of central gravity in SolarSystem/SolarSystem. Just make sure you have the latest version and set the pawn of the GameMode to SolarSystemPawn.

Great stuff! I did however test the Orbit Speed and Rotate Speed parameters, and the sphere chunks were positioned out of sync (image attached). Even with the SolarSystemPawn. Are there other settings also needed?

Edit: I'm also wondering how networking is working right now. I was looking at the documentation, and I can not find the Multiplayer property on voxel world?

Edit again: Also tried building win64 and win32. Gave a few errors:

Phyronnaz Sorry to keep coming to you with issues, but I've run into another issue. When I try to package out the project so that it can be run separately I get the following error part of the way through the package build:

UATHelper: Packaging (Windows (64-bit)): UnrealBuildTool: ERROR: UBT ERROR: Failed to produce item: G:\UE4 Projects\GIE\MarchingCubes-master (2)\MarchingCubes-master\Plugins\Voxel\Binaries\Win64\UE4-Voxel.lib

I tried to start fresh from the project source on the github just to see if it was something that I might have done but I still get the same error. Any ideas?

Phyronnaz Question: What do you think the best way to import height maps into the sphere world generator would be? Or is that even feasible:?

[Phyronnaz]

Wilken VoxelWorlds can't move anymore, I need to figure out how relative positioning works for components. Multiplayer is also broken. When you say "building", do you mean packaging? If not did you try to build with Visual Studio? If it still dosen't work, please create an issue on GitHub.

BinaryScrub Packaging isn't supported for now (editor code used in runtime plugin). Heightmaps could be projected on the sphere, I will look into that.

Hi, just curious: Why not support packaging? Wouldn't the entire reason behind this be to create something others can test and play? Basically, what if I want to prototype and test things outside of the editor with worlds created with the plugin? Thanks!

Yes, I'm sorry, what I meant was indeed packaging. I ended up trying to include the BlueprintGraph module and some other stuff like adding public and private paths, but it didn't sort it out. Hopefully it'll be supported further down the line.

I used the UnrealFastNoise plugin for additional perlin noise support and it works very well with this. Makes for interesting landscapes (and spheroids) by modulating the results from multiple generators, but the noise plugin should probably have a little tweak where it can cache already calculated defaultvalues. I'm trying out a solution for this.

[Phyronnaz]

Packaging is working!

Wilken Would love to see some screenshots

Phyronnaz Tthat's great news! I also saw mentions of solarsystem fix - did you also implement movement already? Oh and of course I can show a few screenshots. I've not looked into the LOD settings and such yet, and that's showing in the pictures, but your codebase is well documented; greatly appreaciated!

Phyronnaz Question: How large is the terrain that is generated with the FlatWorldGenerator? It seems like it goes beyond the playable area within the editor, so how big is it really? Is it infinite? And if not, do you know of any way that I could loop the landscape?

geez... those pics though

Wilken

Movement is indeed working again.

Glad to hear that!

@BinaryScrub

How large is the terrain that is generated

TerrainSize = VoxelSize * 16 * (2 ** Depth)
By default Depth = 13 and VoxelSize = 100, so the default terrain size is 13107200 cm = 131 072 m.
If you need more you can increase Depth, but be careful as it can crash the editor. Also you will quickly run into float precision problem: SetWorldOriginLocation may help for this.

How are you doing the noise on the planets surface?
