Hello once again, got kray a few days ago and, this is what i got so far with kray.

Aside of the whole scene, i have a bit of a problem with the trees, they are instances of two layered objects, one null for each layer. However, nulls get renamed to just the layer name (loose the object name) when i reload the scene. Any way around this without merging the layers?

Comments and suggestions really appreciated, i have been staring at this image for some time now

I had the same problem of the nulls getting renamed once I exit the scene. So in my penguin scene I actually had the penguin in another lwo file and loaded that in the scene. Even if I exit and reload the file the nulls would still point to penuins:penguins and not scene:penguinlayer. I'm not sure though what the solution would be for your case since you have 2layers. Why do you need them in separate layers? Take a look at wiki for instancing tips.
The render looks good. Maybe just adjust the contrast a bit and add some randomness the foliage. They look exactly the same in size and orientation.
The grass looks good. What did you use?
Render time, pc specs, other info?

The leaves are in the second layer, for clipmaps, the whole tree model is on one uvmap. Of course i could change that, but i was hoping there was another way around, i use HDinstance usually.

Ill post the image in PS a bit later, im trying to get some more atmosphere out of the render to start with.

The grass is a simple texture with a few procedurals, looks ok from a distance. Im still thinking about close range grass solutions, it seems that the only option for kray is with a lot of parallel planes, Pavlov did some tests on the newtek forum a while ago i think. I was intending to use kray for animations, so the grass needs to be compatible with that (eg. no postwork like on stills).

As for the render times, im not sure exactly, it took about half an hour on a 8-core 2.8 Xeon... which i think is a lot, although i didnt mess with the settings for this particular image, just medium preset and photon mapping without caustics, RRL is 24. There seems to be a problem with my model as a lot of things get it to crash. Turning on causitcs for instance, delta node on the window panes or the path tracing diffuse model.

I see. So what do you think about kray compared to hd instance?
I also made an attempt to make more "real" grass.

But using clipmapped polys and instancing in kray is too long because of AA. GI was fast though and rendered around an hour in a slow core 2 duo 1.6ghz without the clipmapped grass.
I think using polys would be better than clipmapped polys for kray. I'll have to try it. I'll be interested to see your test with grass next time.
