Test of new idea. Grass and house LW CAD. grass and tree Instant (around 10.000.000 poly) on 4 Giga ram. LWF tonemapping.

Nice ones, especially the grass, are the trees/bushes from evermotion (the million-polygon-company ) ? Looks like you got a job from NCC ??

If You need I will render from ONYX software. ncc name old project.

Excellent. How long is the render time? Your image is a bit small. When I rendered something with kray instanced grass it was very slow in AA pass and it took hours to render even on qc6600. Does kray have something to exclude or better control of render pass per object like 9.5 behind object exclude? Haven't tried that hidden kray hdinstance trick yet though.

Yes there is a shader that you can apply to grass surface. In the shader you control the amount of rays - we usualy use uncached FG min1 max 10... it's enough for vegetation.

I'm sorry, but these images just look weird to me! I'm not sure what is rendered, and what is photographed. How much post-processing/compositing has been done?

Let's start with the bicycle. It's on the shaded side of the house, but you have bright shiny reflections. Okay, if it's chrome, it would reflect the GI in the environment. Fair enough, but it just looks strange to me, and look at the shadows on the tyres. Not quite where they ought to be IMO.

Then you have those odd bar things over the eaves which just look as if they are floating. They don't seem to be casting a shadow either which is odd. If they are above the eaves, they would cast a shadow on the tiles. Perhaps they do and it can't be seen. I don't understand how those things would be fixed to the roof though, it looks like they are stuck on, which isn't right.

The house and patio furniture are brilliant. The timber cladding/siding has just enough blurred reflectivity to look exactly right, and it looks like each plank is modelled because the lighting effects vary from the top to the bottom. The roof tile texture isn't quite right though. If clay they would be more orangey, if concrete, they would have a texture. The instanced grass looks okay, but the flowers spoil it for me.

I don't know, something looks wrong. Normally your work is so close to perfection that criticism seems unfair. This one - I'm just not sure. Some elements look photographic, others not.

Thanks jure,
I used the kray shader before and did that so fg calculation was fast. It was in the AA that it slowed down to a halt. Without the instanced grass it rendered in minutes,

That`s true!
but I try render realistic grass - all power on the grass! rest is only "background" with standart setup.....
btw grass render 2-3 times faster then rest scene
This scene have around 10 milions poly and 3000/1800 pix,time render 1:30 h on my 8 core cpu. Ofcoarse when increse quality this will be ~2 - 2.5 h.

[geo_n]

tnx. will try it again. I went as low as 50 only. I'll try 10. Can you post the bigger res?

[Janusz Biela]

This is rescaled down to 50%.Roof is turned OFF.

Great tests Johnny. Perhaps zoomed limited region renders would show the effect better than large scale ones ...

I am currently doing alot of landscape instance tests with HD I + LW renderer, but will try to find the time to do the same in Kray.

[Pheidian]

Hey!

I think Johny did little too much post processing on these images, since the renders straight from Kray with just minor tweaking of light balance is good. This is little "over the top" for me too

But hey, it's all about the fast grass now as Johny explained, and you CAN make exteriors in Kray, I think that is now proofed.

[Pheidian]

One comment btw on the critics there was... there is NO photographic elements in the image (except for the sky of course), but every tree and leaf and detail you see, is 3D, not after ward edited or photograph... (like the trees in the horizon are real geometry)

Awesome renders! Great work Johnny.
