godot engine crashed with signal 11 when adding VoxelLodTerrain in Godot 3.2.2

[acs]

Hi!

I have compiled Godot 3.2.2 with the voxel module included and when I try to add a VoxelLodTerrain to a Scene with Spatial as the root node, the godot engine core dump with a signal 11. The backtrace:

[godot](3.2.2-stable)$ handle_crash: Program crashed with signal 11
Dumping the backtrace. Please include this when reporting the bug on https://github.com/godotengine/godot/issues

Don't hesitate to ask for more details if needed!

Must be something I didnt check since I made terrains show up in editor. It's trying to generate blocks but by default there is no stream assigned so it calls on a null pointer.

In this case, in order to advance probably I can use the VoxelTerrain using a stream from a file. Right? Thanks for your quick response @Zylann and I will continue playing :) I will test the fix once it is available. My current knowledge of the code base is too limited to help directly in addressing the issue in the code. And I need also to recover my C++ skills acquired some years ago.

Just pushed a few commits to fix VoxelLodTerrain.

Cool! Testing them right now ... and it works for completing the tutorial: https://github.com/Zylann/godot_voxel/blob/master/doc/03_create-terrain.md#create-a-terrain-in-the-editor-voxellodterrain--3d-noise

Tested with Godot 3.2.2-stable tag,

Great! Time to dive into the documentation, the tutorials and at some point, into the code.

Thanks @Zylann . Closing the issue. If I find other issues I will open new issues.

Cheers!
