So whenever I rended the interiors ,it looks really nice,crisp and detailed and with same settings and resolution.On the other hand when I render the exterior of house is looking very flat and bad.
Posted two pics,I am still learning Blender fully now and want to implement it as a main visualization tool in my workflow.This is a demo project I am working on.
The scene looks like a 3D model of a house + a HDRI for the background. In your “exterior” shot there is no interaction between the house and the surrounding (no shadows, no objects in foreground etc.). Also the house intersects with the wall in the HDRI.
Same should be true if you worked on the same scene in 3DSMAX. Therefore I´m not sure if I understood your problem correctly.
(I´m also not sure if the glas is behaving as intended (very dark) and the ceiling has a strong reflection)
One thing I think that is important is exposure, depth of field etc.
When I take a photograph (with a real camera) I do not use the same settings for interior and exterior shots. I always have one finger on the aperture setting and another on speed also if I have to Iso.
Even if you set the camera to automatic ( uurrrrrg ) the camera will take the photos with different apertures and speeds depending on the lighting.
Blender does not have those exact parameters but you can control the amount of light that hits the camera in many ways. Via lighting and colour management.
I often use scene copies in Blender to vary the camera settings, lighting and colour management for interior - exterior shots (and sometimes for just different camera placements).
