It doesn't really matter, but it should be standardized so everybody uses the same convention.
Z-up makes the most conceptual sense for a world space, but because Z forward is the standard for view it is useful to create a Y-up worldspace so characters etc don't have to lie down on their back to be aligned with world when their transforms are zeroed.

Everybody should standardize on Y-up for this reason.

>> No.778137

>>778128
Everybody agree that Z is depth. Z-up comes from how when you look at a map the depth is elevation, north on a map isn't depth.

Anything other than Z-up in world/object space is beyond retarded. Image/Screen space: Z=Depth, XY=Screen Coordinates, World/Object space: Z=Up, XY=Ground Plane. Anything else stems from the retardation of animators.

Feel free to read https://forums.unrealengine.com/community/general-discussion/46691-z-up-vs-y-up-the-solution-to-the-debate-lies-within and learn why Y-Up in a software package that does 3D first and foremost is wrong.

Turks are the attack force of the BLACK race. This is why TÜRKS conquered Europe around the same time the BLACK KANGZ were attacked in Afrika. They destroyed the wh7te capital of CONSTANTINOPLE and replaced it with ISTANBULL, to honour our BLACK BULL (KARA BOGA) nature.
When the African KANGZDOMS were destroyed TÜRKIYE was the last KARA BOGA country on earth. The wh#te subhumans attempted to take it down in order to permanently end the KANGZ and nearly suceeded. Luckily the biggest KARA BOGA of them all, Mustafa JAMAL, fought of the wh1te beasts and created a BLACK utopia in TÜRKIYE. However the nefarious schemes of the wh'tes continued, attempting to bring the KARA BOGA TÜRKS into the E.U. where they would be overwhelmed by gayreek WH9TE immigrants.
Luckily from the furthest we can get from Europe in Turkey, the north east GEORGIAN BLACK territory, a new KARA BOGA rose for the first time since Mustafa JAMAL. RECEP TAYIPP ERDOGAN (REIS) destroyed all wh8te LAICITE devils and restored himself as the KANGZ of TÜRKIYE. Now the BLACK KARA BOGA TÜRKS must struggle against the wh6tes to end that accursed race once and for all.

Being right or wrong about a random factoid about what year something was or wasn't released have nothing to do with ones general intelligence anon.
Neither does being in disagreement over if you can trace max's linage to it's predecessor or not.

If we all stopped being so invested in branding those we disagree with like idiots, even when they actually are such, we might be able to get somewhere.
Getting a rise out of one another only serves to make us all act more stupid.
