Blocky render?

[dibbers]

I've wacked up the levels to make this problem easier to see...

plain light blue environment map in material. Nothing different in set up.

Why has it rendered blocky?

One of your DR machines is not seeing a map, perhaps an HDRI environment map?

[jonnybefree]

different gamma in/output in max settings?

[vlado]

Are there any maps involved either in the environment slot or in the material itself or in V-Ray's reflect/refract override?

Best regards,
Vlado

Just double checked my environment map in the material. I used Checker to give me a plain light blue colour. Doh...the swatches were very slightly different colours.

It renders OK now.

If you have any environment maps in general, make sure that you have any mapping other than "Explicit UVW channel".
