I am getting PSO crash in DX12 everytime when painting more than 6 layers on landscape. There is some limit landscape material complexity before it gets unstable. No issues with the same landscape material in DX11. Another forum been reporting similar issue via pm. I have sent PSO crashlogs via the crash window.
As another DX12 issue, getting insane drawcall hit 80ms, compared to 9.4ms in DX11. On 7x7km map with 2237 actors and 300k trees/rocks.
Wow thx, I’ll just wait for fix, ty for update I was thinking it was just my rig just no longer being relevant for complexity of world.
No plugins template here after 4.24.2 update.
Yes. Had same problem. You need to get back the files from the prior version as they are not included in this latest hotfix. I use Sourcetree to pull down the release so I was able to select the ispc file(s) and get them back.
im getting this crash error any time i drag or move the camera in any viewport

I’ve already added bCompileChaos = true and bUseChaos = true to UE4Editor.Target.cs but that doesn’t seem to do anything. Also get the same result if set both booleans to false.
Not sure what do here. Anyone know how I can fix this?
How do we use chaos in unreal engine 4.24? The chaos project wont open… it asks me to compile and then fails. Is chaos even functional in 4.24? I see a lot of posts about it possibly not working at all in 4.24
Its awesome works
Waves…
4.24.2 does not have the ispc and isph files for whatever reason. 4.24.1 did. I fixed my problem with my version control to get the files back.
Engine\Source\Runtime\Experimental\Chaos\Private\Chaos\PBDCollisionConstraint.ispc
Engine\Source\Runtime\Experimental\ChaosCore\Public\Chaos\Matrix.isph
etc…
Initially I just did a pull on the release branch but that build failed with the same errors you are getting. I ended up removing everything (entire UnrealEngine folder) and pulling the branch again, it then built correctly.
Hi, After upgrading from 4.23 to 4.24 All alembic files are slow and broken.
They may play for a few seconds then just stop and break apart.
After selecting each asset and reloading they seemed to work fine… bit this created a new issue, I now cannot save anything I get the following error message
“The asset XXXXXX .uassset failed to save
cancel, retry or continue”
So then I completely removed all the assets files and references and started again, painfully importing my alembics as fresh new files, and this worked!, and allowed me to save.
… but then a day later I was extremely disappointed to see these alembics are now broken again after reopening the files.
After trying everything I can multiple times, I went back to version 4.23 which everything works as expected
I also tried 4.24.1 to 4.24.2 and still same problem
Thank you, would really appreciate a fix for this,
After upgrading from 4.24.1 to 4.24.2, I get seam issues on landscapes. Landscape LOD settings do not appear to be affected. Using paint layers to fix this is not working.
Just curious, is this using world comp ?
The Linux spline mesh issue I reported previously actually turned out to be a general Vulkan RHI issue that affects Windows too (if you set your project to Vulkan as the default renderer). I submitted case #00153356 to follow that up - I reproduced with Nvidia driver 441.66.
Here’s a screenshot of the issue, essentially the same as the artefacts on Linux:
you have to compile ue4 from source. can’t use the launcher version
Does Screen Space Global Illumination needs an RTX card to run in UE 4.24?
A few weeks ago, I wrote here, with the same problem, but provided a screenshot, as it turned out, they did not believe me. Now I provide a video, I say immediately there are no effects on the mirror and lamp. But what causes the blue light to appear?
The best way to get issues sorted out is to fill this bug report, describing the steps to reproduce the issue and if possible a small project showing the setup https://www.unrealengine.com/support/report-a-bug, you can add the video to it
I do not think that this is some kind of bug, or something like that. But thanks for the answer, I will send the error there too to which you gave the link.
