vray : render speed and quality with procedural displacement

[levinberg_e]

Hi all,

This is my first post so here goes hehe...

I am attatching two images (600x600px)

The first one was created in modo. It is a simple scene -> 1 camera , 1 directional light , 1 plane.

the plane is a basic material but with 3 procedural noise/cellular maps which are applied as displacement maps with gradients masking and blending each other one (of the layers) out.

literally created in ten minutes.

I was amazed by how easy it is to create such a deep effect.

 

The second image is my attempt to do it in 3ds 2012/vray 2.0

again same setup

1 light,1 plane, 1 camera.

I was having a bit of trouble so I am just going for the First layer of cracks in the wall for now.

basic vray material.

I apply, VrayDisplacementMod, 2d mapping, set displacement depth and render.

 

Now, what I notice:

 

The quality and speed is so much lower with vray surprisingly.

I am sure I am doing something wrong. (Btw I also tried playing around with different GI settings etc.)

 

for one, in the vray version, there are many artifacts visible, and this is at the minimum after i bumped up texture sampling resolutions etc... especially if i zoom in the quality gets lower (does this have to do something with the quality of the base procedural cellular map?)

 

second, in modo rendering time is 36 seconds.

in vray 7 Minutes !

 

I am also sharing the 3ds scene , and vray settings if someone could help ?

 

The reason i am interested in using vray is because I like the high quality of the outdoor renderings and I would like to use such a material for an architectural project I am working on ...

 

Any comment would be highly apprecieted.

Thanks !
