Unreal Studio Beta 4.23 Preview

this is the right approach to update project in newer version.

I have identified and resolved the issue. I will send you a private message here on the forums regarding the cause.

I’m actually asking about the reverse for the collaborative template. If it’s possible to take that back to 4.22 for development on what is considered a stable release, this would allow for testing, modding etc and allow for integration on a 4.23 release, once required plugin dependencies are also stable working on 4.23.

I also appear to have this issue. I’ve updated to 4.23 Preview 4. Datasmith says no update is needed. I went looking due to an apparent bug in the C4D importer. The model UV’s were coming in blank on channel 0 despite looking correct in C4D. Channel 1 has crazy UV’s I did not create. Channel 2 has normal import lightmass UV’s. I noticed that Preview 3 has a C4D UV import issue.

I’m not able to install the Unreal Datasmith Plugin in 4.23 Preview 4. I click install, and nothing happens. Is the datasmith plugin not compatable with Mac unreal engine?

I’m guessing you use a different account when logged into the launcher, because the account you are using here to post hasn’t even registered for the Unreal Studio Beta. You can use the forums here to send me a private message with the details of your other account, and I’ll take a look.

Sorry, but the Datasmith plugin does not currently support Mac. I’ve been informed that this is on the agenda to address in the coming months.

I played with a 90 frame test of a C4D file with melange. I animated a plane with a voronoi fracture and simulated them crumbling. If I cache the animation it did come into unreal. The problem I am having is that the imported animation is not complete. It strangely offset the key frames by 50% of the animation so that it only plays half way in the sequencer. It seems like an import issue or a issue with melange. I was not sure if I might also need to setup a specific frame rate in c4d. I used 30fps for the test but I don’t know if it should be set to a specific value when animating for unreal.

If I go a different route and use alembic, I get the whole animation. But that is not the way I would like to work with this.

I am on 4.23 preview 4 using a fully patched C4D R20 Studio

Make sure you submit the problem to our support team, we will be able to look at the files and fix it if possible!

Works fine using Blueprint startup or trying to use the play button on a level. I tried to launch today to see if some camera issues would be cleared up, but got this error.

I’d noticed this once before when trying to compile C++ code or trying to start a C++ level, but worked around it with Blueprints. I’m running 4.22.3. This didn’t happen when I was running previous versions of the software. I also don’t work in an environment where I can turn off the Windows Platform FIPS validation.

Probably my bad for deciding to use the preview to partake in the jam. I am hitting a ton of issues I have never encountered before particularly with loading times and shared compiling errors/lags/issues.
One of the biggest issues is a landscape material and the inability to paint more than 3 layers onto the same grid tile.

I ended up migrating to the non preview where the materials work fine. I still have the project, perhaps after the jam I will submit a bug report or track down the issue better…

Question: Is the HDRI Backdrop Actor removed in the latest 4.23 preview 8?
In the previous version it was located under the lights section.

**To answer my own question. It’s moved under the plugin section **

thank you!

The Preview has ended, and Unreal Studio 4.23 has officially released!

Thanks to everyone who helped test during the Preview. I am now closing this thread. Please continue any 4.23 discussions in the above linked thread for Studio/Datasmith specific features, or the 4.23 thread for the general engine release.

Cheers
