Terrain and Light Problem:Only half of the radius of pointlight and spotlight touch/cast the terrain

*Please see the attached image, the image itself can explain my question.
I have two light, which is point light and spotlight. Both of them are set in important, has a soft shadow type, and Baking is set to realtime.

For this problem I tried to solve it using the knowledge I get from other forums. So here are the following things I tweak:
1. I changed the value of Pixel Light Count, I put it on "10" (still have the problem).
2. I tried to play with rendering path, forward rendering and deferred rendering (this isn't solve my problem).
3. I also increased the "Scale in Lightmap" to "128" (nothing happened).
4. Tried to play with Color Space, linear and gamma but I still have the problem.
5. I changed the baking from realtime to baked. This solved my problem. But the problem is, I need it to be realtime because my player is using flashlight.

Can you reproduce this in a new empty scene? Or is this only happening in your existing scene? What it the object you are using as a floor? You say "terrain" but this looks like standard geometry to me.

Can you tell us more about your scene setup?

I cannot reproduce this in a new empty scene...

 

I'm sorry for the late reply. I actually reproduce it a while ago but I have still the problem. The object that I'm using is the terrain of the unity. I used the terrain for my floor because I used the feature of terrain that allows the artist to add details on terrain by painting different textures on terrain. So in short, I intentionally made the terrain looks like that (flat).

 

Can you reproduce this is a simple new project with nothing but 1 terrain and 1 light?

If so can you tell us how you set it up?

Can you post some details about your terrain mesh? Can you either give us the details of your terrain? Or can you post the relevant inspectors as screenshots?

 

Just had the same thing - in case anyone else comes across this, check your normal maps are setup correctly!

 

You just saved my game, seeing how simple this was got me hanging my head in shame lol thank you!
