Unreal Engine 4.26 Preview

[NilsonLima]

Cannot use GPU Lightmass plugin with Preview 7. Crashes on launch. Is there no way to revert to preview 6? I really needed to experiment with this.
Also, the Github tree for UE4 seems.... gone?
https://github.com/EpicGames/UnrealE...26.0-preview-6

This link doesn't work for me at all.

You need to have your UE4 account linked to a GitHub account in order to see the link (it works fine for me). You do it by creating an user at GitHub and then using that user information and mention at your user profile where it asks to connect to GitHub in this link: https://www.unrealengine.com/account/connections

does it replace Apex cloth ?
Can chaos cloth collide with the environment ?

Well now I feel silly. Thanks for the help!

Not at all, that is more of a common issue than you think, but remember also that you need to be logged in with GitHub always in order to see the link, otherwise you will receive the same error.

Using Visual Studio to build the preview takes a long time. Anything I am missing to speed up that process?
Took about 3hrs to build.

Except for upgrading hardware? Not much

Make sure to use an nvme drive if possible. With a 3950X and decent nvme it builds in around 14-15min.

Hi. Can't you add a feature such as use LOD 0 of all scene objects when rendering to High Quality Media Export? Just like vray. While I can use multiple LODs while navigating the scene, I want to render only LOD 0 during rendering.

[neighborlee]

What does, excuse me if that went a little over my head, that have to do with a compiler error ? I'm not expert on anything compilation , but....
Having said that, I did put .ShaderDevelopmentMode' in ConsoleVariables.ini. I did enable engine to start loading newly copied project, but instead of stopping at 45% it made it to 57%, stil no love LOL

Anyway...NEW while you should have SAID who you were replying to , LOL .

I reiterate, your repsonse did NOT solve my issue in case anyone thinks it did

The CVar for ray traced shadow samples has no effect:

Compiled today 4.26 tree from github. GPU lightmass doesn't support bsp geometry actors. They seem to be ignored by gpu lightmass (don't cast and don't receive shadows). Checked on sanctuary map of ShooterGame example. CPU lightmass works just fine.

Reproduced bug on archivis template.
1. Enable all gpu lightmass requirements.
2. Change all lights to static.
3. Reset world settings - lightmass.
4. Add some bsp geometry.
5. Bake cpu lightmass. it's ok.
6. Bake gpu lightmass. It's not ok - bsp geometry doesn't cast shadows.

You should probably report this using official bug report form.

When ist Twinmotion import to Unreal coming?

[Arkiras]

GPU lightmass doesn't support bsp geometry actors.

Most likely this is because GPU lightmass uses raytracing and BSP geometry is not supported by raytracing
