more kray test

[geo_n]

Doing some more test with new model. shadows and details on fg(noninterp) are more defined though. Interpolated FG is fast.

FG render time 97min


kray render time 40min


FG inter render time 10min

outdated

What Cpu You use?
Great contrast, bad AA

[geo_n]

My renders are using home laptop core 2 duo 1.6ghz. I should put it in signature.
How do i put that in render info header commands?

I'm using medium aa with mitchel. Should I upsample it? The slanted lines look jagged on the screen.

[Janusz Biela]

Try FSAA G4 or G5 Mitchel.
for info You can post this in HEADER:
renderinfo '%kray %ver %time | Core2duo 1.6ghz'; usemultipass 0;previewsize 5000,5000;

usemultipass 0; make FSAA in one pass.
previewsize 5000,5000; make preview window Kray render to maximum size 5000/5000 pix

Thanks. Now I have a big problem. I just added a wine glass object to the scene and the render time went up a lot! Dont know what's wrong. The glass has common glass material and I removed the airpolygons.
i think there should be a basic material library for kray available that's been tested to work efficiently. I checked the glass material in kray interior tutorial 1.7 and it seems different setting is needed.

[Janusz Biela]

hmmm.... just try it (no double sides on glass! just basic setup)
Glass in Kray is perfect and fast.
Ofcoarse You can use fallow on colours and diffuse when You need.

[geo_n]

Thanks johny. Will try again.

[geo_n]

really got a render slowdown with glass object. It happens in prerender its so slow

glass material from jure's interior tutorial on the left and johny's glass ono the right. 20 min low photon, medium qc fg, medium aa.

[geo_n]

without the glass. 3min render. yay

[Janusz Biela]

hmmm...this glass seems bad.
How many bounce You use? Do You turn ON FG reflections and FG transparency/refraction? (this make better quality).
This is my old render (Only HDRi as light) 6 bounce light.

[geo_n]

Recursion 6. Both fg on. I think its just bad environment or because there's no environment so the glass looks horrible. kray glass has 100 diffuse, 0 spec, 0 gloss, 0 refl. Seems weird setting to me.
But still I dont understand why its so slow in prerendering.

Hello, i now have the same problem with glass. Super slow render times with this.

But whith some test the problem that increment x5 render time is reflection bluring. This is on 0% but work....

I add to my glass the "KraySurfaceOption" to control Reflection bluring and render times now are fine!

Try Node Dielectric: this is POWERFULL node glass. For example : set color green and refraction 1.3. This is all! You will recive extra quality glass with nice green effecy on the borders. I thing this is much faster glass then normal LW glass and better realistic.
This node great render milk glass or blurres surfaces just need some tweak.
