Game taking extremely long to build?

So I am still learning how to program and I made a very small testing game to test spawning. It only has 10 objects (two of these are models that have smaller parts) but it is taking way to long to build. At first when I had a blank plane as the floor it build in literally two seconds but I decided I wanted to look better so I added a small terrain with a grass texture as the floor and so far the game has been building for over three hours. It says “Building scene 0: horse (7/11 Light Transport | 63 jobs)” The thing is this is only one scene with a few objects what happens when I want to export a full game with hundreds of objects, multiple scenes, and animations? It would take days maybe even weeks to export at this rate. So how can I speed up build time on my Unity?

As long and the project is saved, try closing Unity and reopen. Also, make sure that in the build scene you only have one scene selected that you are going to export. For example, don’t try exporting the scenes that come with the standard assets. Hope it helps!

I have tried exporting a few times and still no luck. Also the only scene is the one I am trying to export. I’m about to try to export for the fourth time but if this fails then do you have any ideas?

What platform are you exporting to?

Its still baking, try adjusting bake settings or disabling them from Window/Lighting

Terrain baking takes quite a long time…
