There is no advantage, and no difference really. It is not confusing if you just use the naming conventions, pitch, yaw, roll. Good luck!

I noticed the same thing, it appears to be really silly and annoying but I’m sure there is a historical reason for it. Either way it’s just a small annoyance that you’ll get used to soon enough.

Hello, I just discovered that in rotators, when the pitch (y) goes over 90 or under -90, roll (x) & yaw (z) are subtract by 180 and y goes the over way (the exact formula is y<0 ? (-90 + (-90 -y)) : (90 + (90 -x))) It's causing me...

Multiple exciton generation (MEG), where two or more electron–hole pairs are produced from the absorption of one high-energy photon, could increase the efficiency of light absorbing devices. However, demonstrations of the effect are still scarce in photocatalytic hydrogen production. Moreover, many photocatalytic systems for overall water splitting suffer from poor charge carrier separation. Here we show that a CdTe quantum dot/vanadium-doped indium sulphide (CdTe/V-In2S3) photocatalyst has a built-in electric field and cascade energy band structure sufficient to effectively extract excitons and separate carriers, allowing MEG to be exploited for hydrogen production. We achieve a tunable energy band structure through quantum effects in CdTe and doping engineering of V-In2S3, which induces a 14-fold enhancement in the CdTe/V-In2S3 interfacial built-in electric field intensity relative to pristine CdTe/V-In2S3. We report an internal quantum efficiency of 114% at 350 nm for photocatalytic hydrogen production, demonstrating the utilization of MEG effects. The solar-to-hydrogen efficiency is 1.31%.

It’s really confusing to me that UE mixes x,y,z rotations with pitch, yaw, and roll rotations. If I make a rotator in C++ for example I have to give the angles in order pitch, yaw and roll. However, in the blueprint class editor, rotations are in x, y, and z. So pitch, yaw and rolls would be y, z, and x… Not only different names, but also a different order. Besides the names and the order, is there any other differences between these two systems? If not, what is the advantage of using both systems in one engine? It seems so pointlessly confusing…
