Invisible chunks

[aaron-jencks]

Love your tutorial, but I'm struggling to get my voxels to appear, I'm on part 4 right now, my textures seemed to work okay for part 3, but now nothing shows up, I cloned the repository, and it appears this is a bug with the source scripts and I don't know how to fix it. If all of the blocks are the same type it runs fine, but when I fill the materials list with the 12 blocks on the texture sheet, everything disappears, but no errors are thrown.

I have the textures set up as follows

Size: 12
Everything is solid
Stone:
0,0,0,0,0,0
Dirt:
1,1,1,1,1,1
Grass:
2,2,7,1,2,2
Coal:
3,3,3,3,3,3
Planks:
4,4,4,4,4,4
Log:
5,5,6,6,5,5
Cobble:
8,8,8,8,8,8
Bedrock:
9,9,9,9,9,9
Sand:
10,10,10,10,10,10
Brick:
11,11,11,11,11,11
Furnace:
13,12,15,15,13,13
Lit Furnace:
13,14,15,15,13,13

I'm using the source scripts straight from part 4, I went back and swapped my code out for the original and the problem persists.

This is what it looks like when I hit play:

I was having the same problem, found that it was a problem with the air block, you might need to set its renderfaces to true.

Got the same problem! i dont really understand what you mean with the 'air' block...would you mind explaining how you fixed this?...if you did that is

you need a air block in id 0 marked as transparent and not solid, i mean the array of blocks need a value of air in this case was to be 0

Air blocks don't exist as of episode 4 but yours works just fine. Just like iggy12345 up at the top, I cloned the files but the chunks are still invisible. I went through every single line of code but it still is buggy. Any ideas?

Also, I tried putting an air block in slot 0 with solidity off and it still didn't work.

If anyone is still having this problem, you need to change this bit of code to fix it:
`
void PopulateVoxelMap()
{

	for (int y = 0; y < VoxelData.ChunkHeight; y++)
	{
		for (int x = 0; x < VoxelData.ChunkWidth; x++)
		{
			for (int z = 0; z < VoxelData.ChunkWidth; z++)
			{

				if (y < 1)
					voxelMap[x, y, z] = 0;
				else if (y == VoxelData.ChunkHeight - 1)
					voxelMap[x, y, z] = 3;   <---------Change this to 2
				else
					voxelMap[x, y, z] = 1;

			}
		}
	}

}`

If anyone is still having this problem, you need to change this bit of code to fix it:

...
voxelMap[x, y, z] = 3;   <---------Change this to 2
...

I have the same problem even using this solution.
The only way I can find to show the Chunks is by changing the following line:

bool CheckVoxel(Vector3 pos) {
	...
	if (!IsVoxelInChunk(x, y, z))
		// return world.blocktypes[world.GetVoxel(pos + position)].isSolid;
		return false;
	...
}

But this causes the inner triangles to still be rendered...
