I’ve had a problem with the player interaction system. For some reason, in the standalone build the objects weren’t glowing when the player was looking directly at them.

A quick search on Unity Answers brought up this. It turns out that the standalone compiler only compilers shaders that are actually being referenced by an object in the scene. However, the objects that the player interacts with don’t reference the _EMISSION shader, so it wasn’t being included during the build.

Here’s two images to quickly show the difference. The first one shows the Editor, the second shows the build. In the second one, the object I’m looking at (an ammo box) is entirely unchanged.

The solution, as provided by argosys_ops in the Unity Answers link above, is to add a cube with an emissive material to the scene and then build the scene. This will add the _EMISSION shader to the list of referenced shaders, and it’s now working in the build.
