Hi, everybody!

As most of you I am also playing with instances and loving it

But I came across a interesting issue when rendering grass.

I took Janus's scene grass (http://www.kraytracing.com/joomla/forum ... =viewtopic) - played with materials and this is what i got:

This is grass material with specular and glossines - render time 8 min And this is material with reflection and blurring - render time 23 min So... i would like to have a render with reflection on grass material but with render time that is faster than 23 min!!!

Both materials have kray surface options activated....

Is this issue connected with the fact that we a dealing with instances and not proxys? Would renders be faster with proxys?

I does not matter instance or proxy, this is just another (Proxy are better, because save RAM memory) way for clone. Still You have to (I mean render engine) calculate millions of poly...and this is impossible over jump. Matter is with engine which will be better in K3.0 (because Kray has problem with small objects in scene -that object as grass, leafs should be calculate with GI by pixel not by poly, imho). You have to limited reflection on the leafs from NODEs, for example 2-3 bounce...and wait for K3.0 which will solve the problem.
In attachment NODE with limited reflection, so You can reduce speed of render....but of course no miracles.
Also AA is important (to smooth complicate shapes...there is battlefield with time) G. promised new AA which also decrease time of render .

well, it seems like i am doing something wrong... render times are almost the same with limited bounce or without... i am attaching the link to scene

just realised... i forgot to turn off lw light in the scene... it affects the look of the render but not the render time

hehehehe....correction.... the extra light did affect the render time .. now i got it to 16min

Hom much CPU power?

i7-2600 @3,40 gHz 16GB RAM

why? is it a good render time or bad?

It would be nice make all kind of fur with fiber fx... Can we expect a time in which kray will see fiber fx?
