LWJGL transparency issues

#1

Okay, so the past three days I’ve been playing around with a voxel engine, and right now I’m working on water and semi-transparent textures. However, I’ve hit a wall. Or rather, a number of walls.

Now, the weird thing is this: the water tiles at the moment have a custom render code, and it will only ever render a top face, yet it will show these weird faces. However, if you turn around, these faces disappear like so:

Does anyone know what would cause this?

#2

It looks like a simple render order problem. Are you sorting and rendering back to front?

Edit: Also, make sure you are rendering all opaque voxels before any transparent stuff. That could be the main issue.

#3

Well, it’s a start I guess.

Resorted how the voxels are rendered, and it removed part of the problem. However, the faces still seem to pop up on the chunk boundaries.

#4

Then sort the chunks back to front. :wink: Or render ALL opaque tiles then transparent tiles.
