Hey guys How do i create a level in realitykit ? and how do i then load it in code ? is it a file i need to drag and drop into the xcode the same as .reality file i use for assets? Thank you

Hello ! Thank you guys for all the hard work you are doing on RealityKit For now in my studying Im trying to understand, in general, what will cause my Main app view to redraw everything? Or any view? If i have a struct that use the view protocol, and that struct is being called inside RealityView on the main app, or outside a reality view within a ZStack on the main app, if this view updates, does this will cause everything in my main app view to redraw as well? Or is it only true to @State variables of the main app? or the @State variables of the external view i try to implement? and what about @Observable ? Is there an accurate table that tells the developer what will cause a redraw of things? (not only the things the logic asks for, but all things sitting idle within the view) I try to understand how to separate UI updates, to avoid full redraw of things that havent been changed. to minimize UI compute in my games Before i play around with instruments i need to understand the general architecture.. if i work in a way that is counter designed to the way reality kit should work then the instrument results will not make sense to me. so i feel like i should ask you guys first. Depending on your answer i will know how to arrange my data in my game. And how to design and instantiate all my views Thanks

Hello, Im watching this tutorial: https://www.youtube.com/watch?v=tNkvu-YUVro&t=241s I have a reality composer project saved But she does not explain step by step what directory to import, how exactly to import it, and where exactly to import it to I tried to drag and drop every folder level into xcode and also into finder, 1 by 1, nothing works. it does not recognize my contentBundle in code. if someone from apple can upload 2 screenshots sowing the proper way to do this in 2026 it will be awesome Thanks guys :)

Hello, I have an app preset meant for none vr/ar game. Th RCP3 was linked to the xcode successfully. I want to do everything in code as much as possible. not inside RCP3. So i would like to load my assets into variables in xcode, and then initialize them the way i like. (Get entities, get each of their ModelComponents, and place those components in my own array) But for some reason i cant get xcode to load my linked content using the API commands. Maybe it have something to do with the fact im using the APP present not an visionOS preset? xcode cant find the RCP3 project. if i drag and drop the realitycomposerpro into my xcode outliner, it will find the project but will refuse to find any entity or root Is it possible to have please a baby step tutorial from start to finish how to import content from RCP3 beta 3 into xcode Version 26.5 using the app preset ? Thank you

Hello guys, Reality composer pro really packed with a lot of math tools. i can easily create modular textures just as good as substance painter's smart materials and then reuse them across my games with minor node seed changes. The problem is, they will calculate in real time. Considering every game needs baked textures, Is there any future plans to develop a baking system inside reality composer pro ?

Its an honest question, while VR and AR are a cool thing, they are a bit far from what the vast majority of gaming is. (wither mobile or none mobile) Im only a few weeks with the system, but it think its insanely powerful as a game dev tool.Data orient based with ECS, fast, seamless, frictionless, well thought, optimized and packed everything needed. Just my humble opinion, Maybe consider naming it Apple Game Engine / Apple Game Framework - it will attract a lot of developers who just want to make games and are tired of the bloated and messy unreal and unity, tired of being chained into a bloated OOP hierarchy. "Reality" within the name of the kit, as a concept scares away a lot of developers, they think its just a tool only for VR, they dont know its actually a complete powerful and optimized framework to create any game you want. It have so many advantages over unreal. Unreal wraps everything in proprietary objects, forcing you learn mountains of made up keywords even if you already know native C++ A lot of developers are attracted to rayLib because of how bloated commercial game engines are, they dont know Reality Kit is actually a better solution then a lot of framework libraries out there. Just my thoughts,Maybe it finds its way to some folks in marketing. Either way thank you for creating this framework. its absolutely amazing to use

Hello guys I want to use Reality Kit 3 for none AR games. Coming from unreal (7y) I have a few technical questions if i may please: (all questions are assuming my game will handle 50-500 enemies on screen) How does RTK3 handle everything under the hood? its easy to create a struct that hold multiple floats as a data blocks for the system to handle (like hp, dmg, ect), but, what happen when i want generic ASSET data (materials, meshes) ? What if i want to construct a material and hand a cheap id to the processor (system) ? while make sure i packed it nicely to the cpu's cache line . There is not much in the documentation to explain the under the hood architecture of the system for me to make educated decision abut my code. i try to avoid reference bloat in my game, and make sure the system does not coupled new material or new mesh every time it want to perform a generic command on the entity (in 60 fps) For example, in unreal mass, as bloated and over complicated it is - its pretty clear to me what is construction phase, what is the recommended way to generate my data blocks (called fragments there) and how exactly to use them in the system so its all tightly packed At this moment my only assumption is to create a 3 layers custom system to make sure its all running properly: The builder of the pool - it will do the " let shinyMetal = SimpleMaterial(color: ... ect" and save it on some dictionary map the data block - just a simple struct that hold a thin reference to the pool that can be use as a component in the ECS the system - The RTK3 built is system real time . can use the struct as a component and even swap the id in real time is this safe consider how RTK3 build under the hood? or is this even slower ? i have very little to go by. if reality kit engineer can reply and help me here it would be awesome :) Thank you so much for reading guys ! was kinda long. cheers
