road turns dirty while rendering by using vray map in exterior rendering

[nitinrave]

hi

i am animating car on road , but the road turns dirty .

i am rendering by taking iradiance and light cache map.

by taking 15th frame vray map.

 

but if i render it without taking vray map than it renders good without spoiling road.

 

pl guide me.

Please post your render. Also IR and LC setup.

Hi Nitin,

I prefer light cache for interior scene.

Use nth frame 5 or 10,depending on scene.

Some times you need to render without irradiance.

Try the one which gives you better result.
