10 Reasons NOT to use Unity as your game engine

Unity3D has undoubtedly been a popular game engine choice for many developers, especially indie developers, due to its ease of use, cross-platform capabilities, and extensive asset store. However, like any software, it has its drawbacks that may make it less suitable for certain projects or teams. In this blog post, we’ll delve into the ten worst aspects of Unity3D, shedding light on some of the frustrations and limitations that users may encounter.

  1. Import, reimport, reimport, reimport, reimport: One of the most frustrating aspects of Unity is the constant need to reimport assets. Whether it’s textures, models, or scripts, making changes often requires multiple reimports, leading to inefficiencies and delays in the development process.
  2. Way behind Unreal on critical technology (Nanites): Unity has been criticized for being slower to adopt cutting-edge technologies, such as Unreal Engine’s Nanite virtualized geometry, which allows for incredibly detailed environments without performance loss. This can be a significant disadvantage for developers looking to create visually stunning and optimized games.
  3. Fragmented feature sets among different render pipelines: Unity’s three main render pipelines – Built-in Render Pipeline (BRP), Universal Render Pipeline (URP), and High Definition Render Pipeline (HDRP) – have fragmented feature sets. This creates confusion for developers who may need to switch pipelines or encounter limitations that hinder their vision.
  4. Fragmented documentation among different render pipelines AND different versions: Documentation in Unity can be a mixed bag, particularly when it comes to render pipelines and different Unity versions. Often, documentation can be outdated, incomplete, or confusing, making it challenging for developers to find accurate information and troubleshoot problems effectively.
  5. Platform inconsistencies: Developers often face issues where features that work flawlessly in the Unity editor do not function as expected on the target platform. Even for popular platforms like Windows, problems may persist, such as struggles with HDRP Area lights that fail to work correctly.
  6. Integration with popular modeling software is never seamless (Blender): Integrating Unity with popular 3D modeling software like Blender can be a cumbersome process. Issues with importing, exporting, and maintaining proper object hierarchies can lead to time-consuming workarounds and hinder a smooth development pipeline.
  7. Team Development is hard (Meta files, scene merges): Unity relies on meta files to store crucial information about assets, which can create conflicts during team development. Merging scenes and handling version control can be difficult and error-prone, leading to wasted time and effort.
  8. Long compile times: Even for relatively simple projects, Unity’s compile times can become painfully long, causing productivity setbacks and frustrations for developers who need rapid iteration.
  9. Long bake times that often don’t even work: The baking process in Unity, used for pre-calculating lighting, can be time-consuming, and sometimes the results may not be as expected. Frequent issues with lighting artifacts and discrepancies may arise, adding to the frustration during development.
  10. Expensive, yet updates aren’t coming fast enough: Unity’s pricing structure may not be as budget-friendly for small indie developers. However, some users argue that despite the cost, the engine’s updates and improvements often lag behind expectations, making it difficult for developers to stay up-to-date with the latest technologies and features.

While Unity3D remains a popular choice for many game developers, it’s essential to acknowledge its limitations and drawbacks. From the frustrating import process and fragmented documentation to platform inconsistencies and long compile times, Unity has its fair share of issues that can hinder development productivity. Despite these downsides, it’s essential to remember that no game engine is perfect, and developers must carefully evaluate their project requirements and team capabilities before choosing the best engine for their game development journey.

  1. Oh boy, I love a good roast session on Unity. I’ve trudged through that reimport mire more times than I care to count. The import dance should be an achievement unlock in itself. But seriously, “innovation” isn’t Unity’s middle name, is it? Unreal’s got them on the ropes with Nanite tech. Makes you wonder when Unity’s going to step up their game.

    Then there’s the HDRP and URP divide. Feels like I need a Ph.D. to decide which pipeline to commit to without regretting it a month down the line. And that’s only if you can actually find up-to-date documentation that doesn’t require interpreting ancient hieroglyphs.

    And don’t even get me started on the whole Blender integration ordeal. I’ve had smoother experiences flossing with barbed wire. But hey, at least when you finally get that beautiful scene all lit up after a gazillion bake attempts, you can … oh, wait, it probably doesn’t even look right. Well, at least we’re all getting our money’s worth from those speedy updates… oh, wait again.

    Sometimes I wonder if those choosing Unity are just masochists in denial, or maybe it’s just me? What’s everyone else’s biggest pet peeve with Unity? Or, dare I ask, is there actually someone out there who’s found the magic formula to make it all work seamlessly?

    1. Ha, masochists in denial – too right, dude. It’s like we’re gluttons for punishment with Unity’s quirks. But serious question, anyone find any secret sauce or we just stuck in this endless loop of ‘patch, pray, and push-on’?

    2. The struggle with Unity’s reimport dance is so relatable. It’s like doing chores before fun, isn’t it? And your comment on Nanite tech hits the nail on the head. Unity’s been playing catch-up, and it’s not just the import system that’s a few steps behind; their features compared to cutting-edge Unreal tech like Nanite can make Unity feel a tad dated. I get that no engine’s perfect, but it feels like Unity could use a serious boost in that area.

      You got me nodding my head about the pipeline dilemma, Yorick. It’s like Unity’s serving up a three-course meal where each dish doesn’t quite mesh with the others. Makes me wish for a unified rendering streamlining system, you know?

      Blender integration’s been a sore spot for so many. When it’s supposed to be all about fostering creativity, these tech hiccups can really throw a wrench in your flow.

      Here’s hoping they’re listening and we’ll all see improvements soon, ’cause those update speeds seem glacial sometimes! Anyways, fingers crossed for better days with Unity—or maybe the allure of Unreal might just convince more to jump ship.

      1. Yeah, the pipeline mess indeed makes it feel disjointed. Unity’s got potential, but it’s rough around the edges and lags behind Unreal. Fingers crossed, though!
