Hello everyone!
I have a problem that i don’t understand… i use niagara system to create and spawn FX in my game.
No problem in editor, FX are spawn properly but when i build package to have a standalone, big problem! FX are spawned but instead of effects, i have grey square checkboard
Honestly, i don’t understand, did i do something wrong? did i need to check an option?
Thanks
Those are either Shader Compilation or missing Asset References or maybe Failed Shader.
To find its root, you have to look for warnings while packaging (if any in output log)
and maybe just play on level (to compile Shaders) then try packaging it and see if occur again.
Indead i found the problem but not the solution… my FX folder (with mat) are skipped in import
“LogStreaming: Display: ImportPackages: SkipPackage:”
“Skipping non mounted imported package”
Hmm, Is it marketplace Asset? if yes then can you Import it in Empty Project and Try Packaging, If problem occur then it might be Some Mistake from Creator Side and Maybe Contacting him would Help to Fix Problem
Yes indead it’s a marketplace asset and i copying in other folder… i found a link problem, i try a new package
I stil have the problem… i really don’t know… i start again from scratch a new FX (niagara system) and the texture bug is still present
Did the Marketplace Creator of the VFX Pack not help? What was his response?
It is difficult for us to help without having the Project/Marketplace Product that you are having issues with to investigate properly.
Well like i said, i create a niagara from scratch with asset created by me and i still have the problem 
Are you Marketplace Creator?
Can you share screenshots of Error and Warning Logs (Yellow and Red) that you were getting while Packaging.
Also have you made sure that Shader is Compiling Properly (In Material Log on Bottom) and has not any kind of Asset or Reference Issues?
Also it would be great if you would record video of Offending FX.
No no i’m not a creator, i’m just doing some stuff locally 
here my niagara effect:
and here the problem in build:
In log i don’t have any warning or red flag… i’m relatively new in UE so i don’t have all the answer to fix my problem 
After Looking these Images, I think you are trying to achieve Fire Smoke Effect?
If So then do you really need “Smoke Emitter” and “Smoke001 Emitter” together? by looking at these Images it seems like “Smoke Emitter” might be root cause, can you try Disabling Sprite Rendered in “Smoke Emitter” only?
Also now I am pretty much sure that it is not related to Shared Compiling or Asset Reference Issue instead it seems like Material / Texture Issue.
If disabling Sprite Rendered didn’t solved Issue then can you share Material Graph Photo of Material that is Assigned on “Smoke Emitter”.
Kind of, just smoke effect!
I already try to desactivate one emitter but even with that, i have the problem…
Here my smoke material:
I don’t understand your last section, you want that i try to disable the sprite renderer? but if i disable it, it won’t appear in build
The Last Setting in the Emitter, In the Above Image.
If that didn’t work then try this-
I have a Simple Smoke Material-
You can try this simple Unlit Smoke Material, It works for me.
Also I have never tried/used Substrate, that may be the cause?
Ok i spot the problem but i don’t know the solution
I just try to make a build from my pc and not on my build machine, i change some param in package settings and miracle, the FX are good! problem, i don’t know the good param…
I am happy to hear that you have found Problem and atleast make it working.
If it was Fixed by Packaging Settings, the possible reason could be Missing Asset Reference or Dependencies.
and Possibly it was caused by Exclude Editor content Setting found in Packaging Setting or some other settings that are for Including Array of Levels, Dependencies, etc.
But as you stated in Previous Responses that you have tried Packaging in New Project. So, if these Settings were not Messed then it should work Fine.
I try Exclude Editor Content option but the cook fail 
and for other options i don’t know where to find them
But thanks for your answers! hope it will work soon lol
Problem solved!!!
I don’t really know if it’s param package or some assets taged as commited but not… anyway it’s work now, thanks
