new all in one transform adjust ui is amazing, nice to have more powerful level editing tools in UE

[@krz9000]

i love the work you do there with unreal. DCC roundtrips are just awfull timekillers!

[@benveasey7474]

1) Will there be numerical input for precision modeling in 5.2? 2) Is there a way to export out to a vector file (such as SVG) for creating technical drawings from our models? It would be great if Unreal could produce sections and elevations in a similar way to Twinmotion.

[@theone8625]

PLEASE ADD THIS ASAP IF YOU HAVEN'T ALREADY: NUMERICAL MEASUREMENT UNITS (MILLIMETERS, INCHES ETC) FOR PRECISION MODELING AND A UNIT-BASED MEASUREMENT SYSTEM FOR PRECISELY IDENTIFYING REAL WORLD DISTANCES BETWEEN OBJECTS (LIKE WHAT IS IN BLENDER / 3DS MAX).

[@benveasey7474]

@@theone8625 Absolutely agree! It is one of the main things holding a lot of people back from trying the modeling tools.

[@theone8625]

​​@@benveasey7474 Yes! You know! It is absolutely killing our ability to know precisely what the hell we're designing relative to real world dimensions. It makes modeling in UE insanely inaccurate. You have to have a human-sized model in view at all times just to get a sense of scale / proportionality. If we had the measurement units, we could move so much faster, more accurately and more confidently. I love UE, but this is a desperately critical addition that must be made above and beyond all other new features, bug fixes etc.

[@DevGods]

Unreal uses cm so 100 units is essentially 100cm

[@AlleyKatPr0]

NURBS please.

[@GoatOfTheWoods]

Who uses Nurbs in 2023? And why?

[@AlleyKatPr0]

@@GoatOfTheWoods People who use CAD mainly, and, those who want mathematically perfect shapes based on splines that can be imported into any format for any final application. In addition, UE5+ allows for the importing of NURBS models from Rhino ét all. Another way of looking at this is those who work on hard surface modelling and use NURBS to create models, knowing full well they can be exported into FBX models. Having NURBS modelling inside UE5+ makes it so the engine can interpret splines and convert them into polygonal objects/assets for real time. The entertainment industry use NURBS a lot btw, so, like all of the Star Wars movies recently used NURBS in MODO. There is a lot of instances of NURBS for modelling, but it is mainly hard surface modelling as it is sooooo much easier to model objects using a NURBS workflow...especially true for building weapons, vehicles, cars etc, as these are hard surface, yet, have curves to them, which polygonal modelling is always weaker on. Character modelling is really the domain of Maya and Z-Brush, as it is more like using a 'clay' process, and, Maya is very good on animation posing. Although UE5+ is excellent for animation, even for 2.5D + animation, and, paper animation, but most would agree that Maya is the tool people use the most for a traditional animation project. Flat 2D would be the realm of ToonBoom.

I’m surprised you got all that done without crashing

[@swat37]

real ;_;

[@tsechihhuang]

Is that possible to make a script : "shape grow throught a path" ?? And Animated in Sequencer ?

[@UTube2K6]

This look better flow than construct script for procedural génération. I am going to try. thx a lot.

[@FreestyleMovement]

Does this work inPIE mode ? Asking for us doing midi / osc manipulation live

[@PashaDefragzor]

Will there be any revolutionary changes in level design. For example: the levels are planetary size, so instead of a base plane, users will be able to create a planetary sphere with different gravity options, etc.? Or maybe some hex that will cut your generated planet into a plane of the selected planet size, after some of the planets sectors can be ghosted into water or wasteland ? Some game developers are still based on the concept of creating worlds, such as the work of Robert Howard, who created an entire world by drawing a map and then assigning some properties to certain sectors of the planet. It would be cool if it would be possible to assemble your own fictional planet

[@wewantmoreparty]

Awsome

[@adrianscarlett]

I'd really like to see geometry scripting in c++

[@RyanSchmidtEpic]

Geometry Scripting is built on top of our much larger and more capable C++ geometry library. So if you want to use C++, you can use that library directly. (You can also call all the Geometry Script functions in C++, they are just static C++ functions, but using FDynamicMesh3 directly is generally more efficient than going through UDynamicMesh)
