Though my pc specs were just a 970 , fx8350 and 8gb of ram it pretty much worked fine in p5. One in a while it crashed but it was totally fine, but now it’s completely broken and doesn’t even seem to activate the simulation and it’s just static, no matter what I do it just crashes 
The problem with not having VR builds working until full releases kind of defeats the purpose of Preview builds as obvious issues which turn up once we can actually test on VR devices can then no longer be reported and fixed meaning we need to wait until the next full release. Just my opinion after going through this a few times now… Really wish we could give feedback on new engine builds for mobile vr as well during the Preview feedback stages…
preview 5 bugs
SceneDepth material expression does not function with downsampled Separate Translucency pass. This is a big one.
raytracing,no shadow bug !!!preview 6
I agree 100%, the preview builds should continue until everything can actually be tested.
Any updates to niagara being able to render volume domains ? Been lurking around for that / information about that
4.25p0. Depth test is broken for separate translucency pass, when its screenpercentage is set to anything other than 100.
Would appreciate, if anyone could kindly confirm or deny said behavior on lastest preview version, for it is not on known issues list and it is a disaster of unseen scale if it makes that way into release.
Hey guys, so I am already trying your new groom for 4.25 looked awesome on preview 5, but somehow you bugged it on preview 6. Any thoughts about that? Or am I missing something? I’m importing Houdini groom.
This is exactly what is happening for me right now. The groom turns invisible and the frame rate goes down by a lot.
I can confirm it exists in all previews from 1 to 6. Showstopper bug.
Thanks, Nilson.
This should be escalated. It is a catastrophic regression.
I didn’t even dare to test if DSR features are OK, takes a long time to test this and I am already trying to figure other things which seems broken, but I can’t tell for sure yet.
Files missing in build using 4.25 preview 6
You can see these files in the folders and they work in editor and everything however when building it give errors that the files are missing…
For some reason from 4.25 preview 5 to preview 6 It is not finding all files even though you can see them and use them in editor…
WHAT A STRANGE BUG
this issue only seems to NOT find Material instances even if they are there in the folder and being used??? LOL I want to cry now.

how to reproduce this issue?
make a material instance and duplicate it then in each material instance change the texture it uses, save all then build. the material instances can no longer find the textures that was applied in the instance, but the materials work in editor, you can see they are assigned, but once building it can’t, and game shows as default GRID textures after compile.
nope still broken.
Gotta check this, were not testing packaging yet, but this is so basic that is almost unbelievable this is happening. Ofc I trust your competence on reporting this 
Once I finish some stuff I will get onto this.
in editor:
Compiled game:
the only way i could fix this issue is to add the materials and textures again to overwrite them…that is not a good thing. I lost all my custom edits -.-
now i got a week worth of manually swaping out my textures with the custom ones. Thanks epic
Directional light is not working when using raytracing, i have to uncheck cast raytracing shadows for it to work.
The same thing is with sun and sky system.
If you open the archviz template with raytracing enabled there are no shadows.
How can i make it work?
It worked fine for me, but just for the sake of confirming my steps:
- created a material with 3 parameters: Texture Object Parameter, Texture Parameter 2D and Texture Parameter Cube (the 3 types just to understand if it was happening with a particular one)
- set the textures inside the material for a default texture (engine built ones)
- placed a cube inside level
- created a instance and changed the default textures (all 3) using the start content textures and applied to the placed cube
- placed a second cube inside level
- duplicated the material instance by selecting the first instance at the content browser and typed Ctrl+W
- changed the textures for the 2nd instance (originally the ones 1st instance) to different ones using the start content textures and applied the copy to the second cube
- packaged for Windows 64bit (build configuration = Development)
Visually both are the same. I will upload the sample project in a bit.
@ follow the download link for the test project: https://drive.google.com/file/d/15OLp90OhXpbgKVvWWJNpZsAvL8URKG4q/view?usp=sharing
I would recommend try packaging in your system and see if it works.
If it works, we can deduce that migration from a previous release to 4.25 is somehow messing something, and in this case you will probably need to strip out most of the content from your project and create a bug submission form, explaining the release you used and that migrating it to 4.25 shows this weird behavior.
Hey, anyone who brings in Groom Hairs- did you ever notice that the groom comes in flipped L to R? almost like if it was in a mirror.
Like if in your host app you made a front part combed from L to R, it will come in combed R to L.
You can tweak once in engine, but just was wondering if anyone else saw or noticed that.:rolleyes:
