Skydome is blurred during Arnold render

[domybiz]

Hello my friends, i would like to share my little mistakes about a skydome light.

When I start to render a scene, the skydome is blurred and it doesn't looks very weel.

I try to improve some sample but the result is not so good.

Can you help me please ?

Thank you so much.

I think it is because your skydome is too small. Try scaling it up with r (scale tool) around your scene. After that, your render is going to be higher resolution.

Also, ensure you haven't turned render camera's DepthOfField ON.

Next time, when you post questions like this, post some screenshots/renders too, or zipped MA scene, otherwise people here are forced to guess, which in most cases is a waste of time, will you?
