trueSky UE4 branch builds successfully but doesn't work

Pure trueSky Unreal Engine branch (4.19) builds with no errors but the editior works incorrectly and the sky is black. I emailed trueSky creators (contact@simul.co) but unfortunately got no reply.

What I’ve done:

  • Forked trueSky 4.19 - https://github.com/simul/UnrealEngine/tree/4.19 (it’s private, you must pay for the plugin)
  • Ran Setup.bat and GenerateProjectFiles.bat, then installed trueSky binaries using the .exe-installer (https://simul.co/download/)
  • Built UE4.sln in Development Editor Win64 configuration, no errors were shown.
  • Started debugging UE4 Editor. The editor loaded “choose project” screen, I’ve chosen a new blank one (it doesn’t matter). After that I got “unhandled exception” error:

If I press “Continue” the error keeps popping up. So the only way to avoid this is to Break.

  • Next, the project loads but when I try to set up a TrueSky Sequence Actor I get completely black sky:

By the way, the username and licence strings are not sensitive to what I’m typing in. No matter what I type, I can type a complete garbage, it says “OK”.

  • Finally, when I close the editor it closes and shows this:

​So if anyone has encountered with this issue I would be grateful to find a way to fix this. Any help/piece of advice will be appreciated. Thanks in advance.

You should probably post this on the TrueSky forum thread, sounds like an issue on their end.

Looked for a TrueSky forum without any luck, but that thread is the easiest way to contact the dev’s currently.

Thank you, . Didn’t know there is a relevant thead out there. I’ll post on the thead and will reply in here when the issue is solved.

Hello,I know this…because you packed,you need copy lots of files…

Hi, it says you have to copy/paste files in case you’re using the binary distribution of UE. I’m using engine which is being built from source code. Therefore according to your link I must rebuild UE4.sln in Development configuration. So I’ve done it and ended up with the same issue. I’ve got “unhandled exception” error and the sky is still black.

Thanks for reply but unfortunately your solution doesn’t work.

you remove truesky and repacking…If your project still Fatal error

If someone encountered this issue I have bad news for you. Basically, according to what creator of trueSky said there are incorrect dll’s included to plugin which doesn’t work in 4.19 Engine built from source files. A few months ago he told me the dll’s will be released soon but they are still not ready. No info about when the issue will be fixed.

However, trueSky works fine with a binary distribution of UE4. I’ve tested the plugin in 4.18 and 4.19.
