Splotchiness like that is caused by your GI.

 

Either of these should work;

1) Enable "detail enhancement" on your irradiance map rollout.

2) Render using brute force as a primary GI, try using the Vray Universal Settings

For white cornice details, you should go for ADAPTIVE DMC, try it on 2/6 or 1/8

Tanks Zdravko . I did that but still same . no change .

How about an AO pass for added definition of the cornice.

 

It won't help with any of the dots or splotches, but may help show more of the detail.

hi i did not get the meaning of AO pass . could u pls explain more for me .

Tanx

Try the universal settings and report back. If they don't work then it is a problem with your geometry.

[CliveG]

With regards to AO - it means Ambient Occlusion - there are a few different ways of achieving this depending on your render engine. But a search of old posts here should provide you with all of the information you may need for your render engine.

 

This will only add a bit of definition to your cornice moulding, it won't cure your other problems, you'll need to refer to the other answers for that....

 

Hope this helps.
