Export meshes to FBX and other small changes.

[freezy]

Thanks to @jsm174 for figuring out how to make the damn FBX package work on Linux. I had to cheat a bit for the unit tests too, because somehow the geometry was slightly changed.

The other small change was fixing the locked hierarchy window in one of the provided layouts.

Thanks to @jsm174 for figuring out how to make the damn FBX package work on Linux. I had to cheat a bit for the unit tests too, because somehow the geometry was slightly changed.

Cool. Just for some notes incase we ever have to revisit this:

game-ci's test runner is currently built on Ubuntu 18.04. Out of the box, Ubuntu 18.04 has libstdc++.so.6.0.25 installed.

According to: https://docs.unity3d.com/Packages/com.autodesk.fbx@4.1/manual/index.html, libstdc++.so.6.0.28+ is required.

So as a work around, we need to temporarily use a custom game-ci unity test runner image base on Ubuntu 18 that has an upgraded libstdc++. When game-ci upgrades to Ubuntu 20, we can go back to official images.

To upgrade libstdc++, we made a custom Dockerfile:

FROM unityci/editor:2021.2.15f1-linux-il2cpp-0
RUN apt-get update && apt-get -y install software-properties-common && add-apt-repository -y ppa:ubuntu-toolchain-r/test && apt-get -y install --only-upgrade libstdc++6

docker build . -t jsm174/unityci_editor:2021.2.15f1-linux-il2cpp-0`
docker push jsm174/unityci_editor:2021.2.15f1-linux-il2cpp-0

This article was also helping in tracking this down:

@jsm174 this is ready to merge now, right?

@jsm174 this is ready to merge now, right?

yes. In a future PR we will be able to remove the line: customImage: 'unityci/editor:2021.2.16f1-linux-il2cpp-1'.

I believe game-ci/unity-test-runner needs to make a new release so it pulls its latest image.

[freezy]

Cool, can you watch this and update accordingly?

[jsm174]

@freezy - unity-test-runner@main was just updated to pull v1 images. (game-ci/unity-test-runner#179)

This is good to merge now.

Awesome, thanks!

But I wanted to fix colored material emission before merging. If I don't get to until tomorrow I'll merge nevertheless though.
