[issue]3ds Max vray texture baking

Hi,

i have baked the texture in 3ds max using the vray. once i baked the texture with vray complete map i assigned that textures in that object(simple sphere and plane) and delete the vray light. I got the light effect in 3ds max.

I imported that 3ds file into the unity and assigned the same texture(without compressed) what i have used in the max, but here i cannot get that light effect. Once i add the directional light then i m getting but baked texture dont need any extra light i think.

I have added the screenshot of those images below:
3ds Max, Unity without light, unity with light.
