Global Illumination is not working.

Throughout this video my global illumination has not been working.

I can only imagine that its because I am using unity 5.4? "DynamicsGI.UpdateMaterials (rend);" did not change it. Still not working. Any ideas?

It's set to Real-time on the Lava Shader. The lava is using a standard shader.

I am going to answer my own question. It was due to the exercise files being made for an older version on Unity. After a bit of googling I noticed people talking about the lighting window.

Its under -> Windows -> Lighting

Trying that I noticed I was getting an error "Lighting data asset was built with an incompatible Unity version. Realtime GI will not be used. Please rebuild lighting."

I needed to check the box for Precomputed Realtime GI and click build.

Once I did that GI lighting started working.

I hope that helps anyone else with a similar problem.

I had the same issue and this helped resolve it. Thanks!

Some more details for other who had this issue...

Whenever I hit build, it wasn't actually building anything at first. The button would switch to "Cancel" briefly and then switch back to "Build", and at some point in there it would show some pending jobs in the bottom right, but that would go away too. Something eventually got it to work, but I'm not sure what. I know that when it eventually did start building it took a few minutes, almost as if something was hanging or running excessively long, but I'm not sure how long something like this normally takes.

Thank you!!! This worked for me too. for me, check the box for Precomputed Realtime GI was already clicked.

All i did was hit "build" without changing any other settings. It took about 5 minutes to finish and did not give any feedback that it was building. But within 5 minutes it worked.
