I have some trouble with reflection capture. I have followed “wiki” in all aspects, but reflection map is not updating for me , whatever I try.
If possible, we’d like to try and reproduce your issue.
What version of UE4 are you running?
Also, could you please provide us more information on what hardware you’re running on, which Linux distro you’re using, and your driver configuration?
Knowing your hardware/OS/driver profile will enable us better answer your question.
Thanks!
I believe I am running most recent UE4 version 4.8.1 on Debian 8.0 Jessie x64
Hardware:
Amd fx6300
Nvidia 780Ti (Gigabyte) , with recent 340 driver.
gigabyte 990fxa-ud5
8gb ram
I must say that except reflection maps, everything seems to run perfect.
Today I will also test other card 660Ti I have…
Thank you for quick replay.
I have tested many things, finally I have tested if my scene is running without troubles under windows. And there are no artefacts under windows on my laptop. I would say , artefacts and capture map problem, in my case is related to linux. Other thing is that even thou i have decent laptop with i7 processor 8gb of ram and decent graphic card (gtx 635m), everything is running faster and more smoothly under Linux-PC. Overall experience is better. I have read that there are longer texture and light-maps generation times under Linux but in my case it is opposite… I would rather use Linux so I am greatly interested in solution here. Looking forward to any ideas…
interesting thing is that Setup.sh didn’t installed one dependency for me which is “mono-gmcs”. This package is listed in wiki, where things needed for manual installation are discussed. I have installed this package and rebuild whole unreal but artefacts and problems with capturing reflection maps are still there.
100% complete shot in the dark but did you try and re-build the reflection probe by pressing the Update Captures button on the reflection capture actor?
@Jedrzej - also shooting in the dark, but try these drivers (note that they call out “disco bug” in the readme).
I have tried updating captures individually pressing buttons in captures settings and globaly under “build” button “rebuild captures”. none of this work for me.
And… there is another problem.
I have build my reflections under Windows without ant trouble. Unfortunately both under windows and Linux , after I press “Play button”, all reflections render black:(

@Jedrzej - Regarding the primary issue, did you follow RCL’s recommendation to install the latest NVidia driver?
No. I couldn’t find a way to install this drivers on my Debian system. As soon as I find way to do it , I will report all changes.
