Rendering in Vray issue

hello friends.
Here I have a question please, regarding rendering in V Ray Next with SketchUp. I’m a user of V Ray NEXT 4.3 for SketchUp pro.
Why "Render Interactive image seems more realistic than Normal Render during preview.
During Interactive rendering preview image seems more close to reality, details, shade and shadow look more great. when I make it final render image look fake .Thanks in advanced.

hello, that means your model is not precise enough. Could be in terms of textures, geometry etc.
take the final render and squint your eyes, it’ll look more realistic too…
