Hello guy,
I write cause I have two problems in my neary finished game:
The first is that in the blocks that are building my levels are renderd gaps that appear and disappear. That do not look nice. So I wanted to ask what I can do against it. The Blocks are static, so I did baked the light.
The gaps are switching position and just are vertival.
The Next problem is when I bake these blocks, in some cases the baked object looks strange and you see that these were seperate blocks and no unform shape.
I do use the texture comressing mode ETC1.
So it would really helpful if someone can help me 
And sorry if there are mistakes in my english.
