So in my project, when ever I try to open cascade, it will load up to 100%, and then the editor will crash. This goes for any particle asset, as well as creating a new particle system.
It works fine in another project, so it seems that something has gone wrong in this particular project. Is there anything I try? It would not be a good thing to have to migrate everything to a new project.
Hello SaviorNT -
When the engine crashes are you getting a Crash Reporter pop up? If so, can you post your Machine ID? If not, please look at the linked Wiki page that follows and attach the Windows Event Viewer Logs from the time of the crash, A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums.
Some non-destructive items that you can try:
Let me know -

Here is my machine ID, and I’ll also try the troubleshooting steps you mentioned: MachineId:6883071648C402064263FA92D2C7CA69
Hello -
Also if you would not mind, please share the screen resolution, video card and video driver version number as well (for everything but the screen resolution you can simply attach your DXDIAG).
Thank You
Eric Ketchum
Deleted the folders that you mentioned. Is it normal for the Common/DerivedDataCache to be 22.5GB? :o
My screen resolution is 1920x1080 (x2, dual monitors at the moment), I have also included my dxdiag report. Deleted the folders, and the engine still crashes when I launch cascade in this project with an Access Violation first/second chance not available.link text
One thing to note is that I do have VS2015 Update 1 installed, however, I am working with a blueprint only project. I don’t think this would have anything to do with it though, as I mentioned, Cascade works fine in other projects.
Hi -
So, yes that Common DDC File can be quite large. (I often will delete it ever once and a while and let the engine rebuild it. It will get rid of any old compiled data some from older versions of the engine.)
Is the version of the engine you using a GitHub compiled version or from the Launcher? That is the only thing I can think of that might cause an issue with the Update 1 of Visual Studio 2015.
Let me know and I will continue to try to test -
Eric Ketchum
It’s from the launcher. In my project, so far, all I really need from cascade is to change the occlusion of the particle systems. Is there a way to do this outside of Cascade?
Hi SaviorNT -
I am still having trouble getting a successful reproduction for this issue. If possible can you send your project to us for debugging? If it is small enough you can post it here as an attachment or link via dropbox or google drive. If you would like to keep the project private, feel free to link it to me via the Engine Forums
Thank You
Eric Ketchum
I’ll see what I can do about the size of the project, which is currently at 18GB. Drive’s limit is 15 :\
Update:
Ok, so I removed the KiteDemo from the project using windows explorer (it wouldn’t load in Engine, and I haven’t used any assets in it, yet), cleaned up the redirectors after that. Then I removed the following sample maps:
I got the file size down to a reasonable upload to Drive level, and then I did a test on creating a particle system. Cascade now opens properly. I have no idea why, but it works with a new particle system asset as well as other particle systems that were in downloaded content packs.
edit: As a side note, the following particle effects from the VFX Weather Content Pack from the Marketplace crash the editor with the following Assertion Failed: “Assertion failed: ScreenRadius >= 0.0f [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.10\Engine\Source\Runtime\Renderer\Private\ShadowSetup.cpp] [Line: 1380]

Hi SaviorNT -
IT looks like the crash from those VFX come from a known issue, UE-21208 which has been corrected in 4.11. If it reoccurs in 4.11 for you, please let us know here.
Thank You -
