Hello Guys,

You all can see the different between two images..in vray.. i can get sharp image..with nice edges but in corona the image looks blur..did i do something wrong..i can see everyone post the rendering using corona with sharp and clear image with standard setting..can you all help me..already searched for it on the internet..but still cannot find the answer..

Thanks..
(sorry for my broken english)

There's a blur/sharpen checkbox right in the VFB. Either that, or use an image filter that produces sharper results. The VFB sharpen filter however should do the trick.

Judging by the images in the first post, the real problem here is not the lack of sharpness, but the way Corona washes out the gaps between cabinets doors. This might be because your albedo is too high or because the cabinets themselves aren't modelled correctly.

You could try to lower albedo, fix models or just add occlusion map to the material, so the gaps would appear darker.

vray also not good in this picture, you can see at ceiling GI artifacts what produce dark shadows.

by the way at forum was similar topic about dark shadows between doors, problem was in 3d model
