1. Open a New 2D Sider Scroller Project without Starter Content
2. Change the Background_Sprite's Material to DefaultLitSpriteMaterial (Material'/Paper2D/DefaultLitSpriteMaterial.DefaultLitSpriteMaterial')
3. Add a PointLight at (X=300.000000,Y=-400.000000,Z=1200.000000) with an attenuation radius of 10000.000000
4. Build Lighting
5. PIE

RESULTS: See Attached Image - pointlight_Test.jpg (with the roughness of Background Sprite changes to 0, see Attached Image - pointlight_Rough_Test.jpg)

EXPECTED: No large light streak
