Problematic Static and Stationary Lighting on Mobile
Hi, I built a simple scene targeting for Desktop/Console and now trying to run it on mobile. The scene is a closed tunnel and is lit by two 'long' static point light. With SM5 shaders, it looks like the picture below:
However, after it's built for mobile (ES2), the two static light become really weird. The scene becomes darker and the light looks graded, instead of the continuous gradient with the SM4 shaders. The following is a screenshot of it:
The problem remains when I change the two static lights into stationary lights. But if they are changed into movable light, they no longer look graded (and they are no longer 'long'). The following is a screenshot containing a movable point light and a static point light.
Anyone know why is it happening? The problem arises for both mobile preview and device.

So I ran some tests on my end and did not get the same results you are reporting. Below is a test case example I used to verify what you are reporting.
SM5 Level Preview
I would look at modifying your lightmap resolution for your static mesh object, and make sure the Source Length of the lights are not clipping into the geometry as it can begin to create shadowing artifacts.
Let me know if you have additional questions.
