Hmm, it seems like the CI builds didn't run, maybe because there hasn't been a commit in this repo for a while?

This didn't compile for me though - I think you'll need to update the git submodule for Pinta to build against the latest commit

NightVisionEffect.cs(52,30): error CS0508: 'NightVisionEffect.LaunchConfiguration()': return type must be 'void' to match overridden member 'BaseEffect.LaunchConfiguration()' [/Users/cameron/code/NightVisionEffect/NightVisionAddin/NightVisionAddin.csproj]

I just updated the submodule by running the following:

git clone --recurse-submodules https://github.com/Lehonti/NightVisionEffect_fork.git
cd .\NightVisionEffect_fork\
git submodule update --remote
git add .
git commit -m "update Pinta submodule"
git push origin

However, the build fails.

I see that the problem is related to a constructor, so I will check that.

I added the missing argument to the effect that is created inside Render. I hope this fixes it

Yep looks good now - thanks!
