Hey.
Im using LibGDX + Ashley (ECS) and im trying to draw a list of tiles(entities) with one mesh (each tile has a texture offset and height - for scaling along the y axis).
The problem : nothing shows up on the screen and i have no idea why. I suppose i messed something up with OpenGL calls, as this is my first attempt at 3D.
If you have a better solution than what i have come up with, feel free to share it 
TileRenderSystem.java
Test1.java (Loop Class)
tilesVertexShader.txt
tilesFragmentShader.txt
EDIT: defaultTileSet.png
