What are the "Limits" of UE4?

[anonymous_user_b0cf5855]

With each release/update they have notes on what has changed—HOWEVER–keep in mind that it’s very common for a project to break when you upgrade to a new release. That’s mostly for the new version upgrades like going from 4.10 to 4.11, while there’s smaller hotfixes like going from 4.11.0 to 4.11.1 which should not break your project.
What is recommended is to only upgrade to a new version when it has a feature you really want, like say if dynamic GI was added to the engine in the future. If you choose to upgrade, keep a backup of your project in the old version just in case.

1) So every time someone updates UE4, their projects are going to break?

Do you mean it will break in terms of…
-It wont run
**Or **
-The file itself actually breaks?

Because if its just the file itself and the project will still be able to run on the next version, then every time someone updates they could just move the project to a different HDD then bring it back right?

**geneconcept)**Regarding using UE4 to render(at a higher level than its real time counterpart), instead of real time performance…are there any examples of rendering ability of UE4 in which people have used it to create a cinematic of any kind?

Most of the photo real renderings I’ve seen are of a sofa or a single room architect’s preview for their clients.

**)**I haven’t seen people doing that type of thing, really if you go that option then you need to download the UE4 engine source from the Nvidia branch and compile it so that you can use VXGI. Then you can turn up the dynamic GI quality and render. I’m sure people are doing things like turning up the reflection quality and doing things like Supersampling (render at a higher resolution than your target, then scale it down which will improve anti-aliasing). But there’s other stuff you can do as well, like increase polygon counts, increase texture/lightmap resolutions, all types of stuff that you wouldn’t do in a game when you have to be able to play at 60fps on mid-range hardware.

By the way, if all you’re planing on doing is cinematics, then you don’t have to pay royalty for using UE4. If you do a game that you are going to sell then you would. But not for non-interactive media.

**2a)**Is the only dynamic GI available right now is through the VXGI?

**2b)**What exactly is the difference between the VXGI and the unreleased SVOGI by UE4?

There must be a fundamental difference, I’m sure, since one GI (VXGI)was released and the other GI (SVOGI) wasn’t?

For example…maybe VXGI builds light worse than the SVOGI = better performance = why it was released to public?

3) Is there a name for the method of using UE4, only for rendering, to boost up the quality for cinematic production?

---

4) When it was mentioned of using UE4, only to render…

Previous message) Right, if you want to use UE4 to just render stuff and don’t care about real-time performance then it becomes much easier, you can render things pretty nicely and there’s quality settings that you can turn up if you don’t care so much about it being real-time.

There’s also stuff like Nvidia VXGI which is available for UE4 if you want to try a dynamic global illumination system that you could use and turn up the quality if you don’t are about framerate.

How does this recent message…

Recent message) …in most cases you can’t just turn up the quality or realism since they don’t offer that feature…

…fit together with the original/previous message?

They seem to be complete opposites of each other, but I believe you have a reason for both messages, and that I am the one misunderstanding the messages somewhere along the way.
