Blurring and issues with Radiance Image

[Deweyirl]

Hi All,

I am using IESVE 2017 and need some help with Radiance.

I have modelled a building and trying to work out the Daylight Factor. When I run radiance in either High Quality (HQ) or Medium Quality (MQ) in WP View Iamge, I get a lot of white light into the room. I have attached a link as example.

Can anyone help me to figure out what is causing it?
I have checked and there are no holes in the walls or I did a model rebuild but theses problems are still occuring.
