make sure the verts that border each part connect. What else is there to know?

>>525900
how do you avoid zfightning?

>>525920
You don't see zfighting since they don't overlap.

>>525896
Also, power of 2.

>>525921
two meshes at 0 point overlap

>>525900
>shit, light is leaking through the seams

>>525930
but you don't see both of them at the same time

>>525935
but you do see the edge when they are snapped next to eachother, like walls

>>525946
but you don't see the edges unless you actually put one a little inside of another. in which case it's not modular level design.

>>525948
so whats the way to go about it?

>>527210
Not him

But you should have a block size system for all your pieces.

Let's say you do it in metres:
You can a wall section that is 1x1, 2x1 or 2x3 etc etc.
But not 1.2x3.6. They must align with the grid. Because they align there is no overlap and therefore no Z-fighting.

Have a look at Thiago Klafke Zest Foundation:

If you want a challenge try doing a modular texture too:

Kickass. Thanks familia.
