Vray Render Settings: Image Sampler, Irradiance Map, Light Cache

[legene8]

Dear render gurus!

 

I am posting another question for my rhino vray render.

 

I am doing some renders for A2 board (59.4cm x 42cm).

 

I know we have to increase Image Sampler, Irradiance Map, Light Cache when we want quality production image.

 

My image output in vray is big, its 2048 x 1536.

 

 

But i am still unable to get a better quality for my image. In 'Jpeg 2' the edges are not sharp, the staircases are kinda blurry when i 'view actual pixel' in

photoshop.

 

I used:

 

adaptive DMC image sample: min 3 max 6

 

IR map: min -2, max 0, hsph 90, interp 70,

 

light cache:subdv 2000, number passes 8.

 

 

I would like to seek your advice on what settings are appropriate, for 1) quick viewing & 2)quality production.

 

Thank you in advance!

what about Light parameters?

1st, have you enabled Antialiasing? Without, you will nearly always have some sort or another of crisp edges. Then your settings are unecessarily high IMO. Depending on your lighting setup, an adaptive DMC min value of 0 should speed up rendering times; also, if you dont have a dual cpu setup with eight cores, there's no need to set the lightcache passes to eight (vray needs one core per pass). For testrenders (i.e. until you fixed your rough edges) I'd reduce the lc subdivs to 150-200 to speed up rendering times. Lastly, 2048x1536 is far too small for the print res you're aiming for.
