Calculating lights turns dynamic objects white.

When i calculate my level, all dynamic objects turn bright white and seem to have no shadowing whatsoever.
This has just started to occur and everything has been fine up until now, i suspect the latest build version to be the culprit.

Dynamic objects should remain unaffected after calculating lights right? as a test, i turned all the meshes to dynamic and the results are the attached images.I really dont know whats going on or how to fix it.

Img1 = Before build, all mesh set to dynamic
Img2 = After build complete (1 second build as there isnt any static meshes)
img3 = After build with exposure set to 0

Change the volume light method from volumetric light map to sparse volume light samples located in the lightmass setting in world setting…it solved my problem
