1* 100% Needed… sometimes I have no idea what some nodes do, and I have to run lots of crazy tests, they all should have like a bubble with all their info in the engine and a link for more info, great idea.
5* I still don’t understand the big deal with metahuman, If you are a designer, making a base mesh in Maya or blender, and sculpt it in Zbrush or any other, is a 1 time process, and you can continue to use that mesh all the time, and just edit face features and body shape, and it will be a mesh created for your own needs… thousands of tutorials available, even per free, you also have DAZ 3D with great base meshes and this software exists since 20 years ago, you just have to dedicate time to make your human model realistic or stylized, even animation and expression is not that difficult, but you can also get free MOCAP, honestly it has more benefits for you, because you learn a lot from the designer perspective, for your resume, your projects, and you have models with the exact poly count you need, in the exact mesh areas you want, and even with far more control over the final look.
7* I don’t understand why people keep using behavior trees…, it’s an easy, fast method of AI (like metahuman), but extremely expensive for the engine, once you reach 250 in a close radius, your crown manager starts failing (even increasing the minimum) and FPS can drop dramatically; instead, you can create AI with just 1 single tick in an actor blueprint, and a smarter one too, no C++ needed, all nodes are right there, and then, populate the scene with thousands of IA with a lower cost.
Honestly, if IA has 1 fault, It will be, to be able to navigate in all directions and have gravity in all directions in UE (not just Z), that would be a massive game changer… bigger than Nanite and Lumen combined, just imagine the possibilities, yes, there is a few plugins, but they either fail after packaging or you need their developer to update them - fix issues, and maybe they do it after several months LOL.
