I tried all answers from Internet, press W - "Clear All Restrict Render", uncheck my post processing - "Compositing", recalculate my UV, Ctrl+N, switching back to CPU render, switch to blender render, etc., none of them works in this case. NOt sure if this is because I import the object from makehuman. My object view, material view and render view attached.
Material view:
Object view:
Who knows any other trick I should try?
