HI! Check my progress! http://p3d.in/qOtOs If you can`t navigate viewport (1 of my friends can`t, it just freezed in 1 position), i will make a screenshot
1. Pack what? All the textures? Just add the asset to the package, Unity will do the rest. 2. Just make a clean layout for that asset, no overlaps or stretching, and filling the 0-1 space.
its getting 1 signature every second now. i predict it will be at 186 400 signatures in 24 hours, and if it keeps up, within 1 week it'll be about 600 000 signatures.
yeah i would definitely never waste as much as 1/4 of a texture space. even 1/8 seems like a waste to me, but i've always been a sucker for maximum optimisation :)
Don't need to do this since it would only make since if you were going to unwrap a 1-1 UV and normal map it, but you'd just want to use tiling textures.
When stitching 1 to 2, sometimes you need to stitch 2 to 1. <---(Ancient proverb? LoL) If that doesn't work you can target weld the points, but that's a lot more clicking.
the uv shell of the second object just needs to start where the otherone ends (or with an exact offset of 1 or 1/repetitions in v of your texture). so align them and you are done.
