Emissive Spline ?

Hi, my static mesh emits light as expected when spawned in the level via drag and drop, but when I use it as a spline mesh component the material attached doesn’t emit light, I couldn’t set ‘Use Emissive for Static Lighting’ via blueprint scripting. I tried to make a lightmass settings object and override ‘bUseEmissiveForStaticLighting=true’ but no luck as shown in the picture, does anyone know how to solve this issue ? Thanks is advance

Changed “Shading Model” inside Material editor to “Default Lit”, it solved my problem.
