Re: Maybe a bug: DP fresnel transmission (and solution)
Thanks Janusz, I tested this node from the other post. It works well! The fact is, since all my works and materlas are saved for the 'classic' lw engine, I was trying to run different object and scenes to see what materials I really need to re-setup or if I can keep something. You know, under a dead...

Maybe a bug: DP fresnel transmission (and solution)
I guys, when I was experimenting with Kray demo the other day, I was having some problems that I couldn't figure out. Then I finally found the solution, here's what happens: If you use DP fresnel node and connect transmission 1 or 2 to diffuse or transparency (that's the invert of reflection) the kr...

Re: Some test
Instead of Dielectric Try Colour Filter in LW. It can happen with glass that problem when materials are on stick - it is normal. You get Hot Photons behind chair because of Dielectric (Caustic in Kray.cfg is OFF) Ok, so you are suggesting a fresnel glass with color filter applied, I'll give it a tr...

Re: Some test
Dielectric has bug it makes hot pixels in renders (G. told me it is problem on Dielectric side not Kray) Ouch, so is it better to avoid dielectric? I use this node a lot because I can set the absorption to get colored glass and also a good looking in the thick side of the objects. Is there a way to...

Re: Some test
Ok maybe I found the problem with the wood: the reflection map for blur is simply too strong, and since behave very different from lw is better to resurface if coming from lw. The reflected red is a bit punchy btw, it's like coming from a luminious surface...

Re: Some test
Remember Kray use full bounce light system so having 12 bounce light in Kray is more richer then in LW with 3-6 bounce light (of course you can setup same as in Kray but I am not sure about speed render in LW and transport of light - it can be difference. For Kray is doesn`t matter 10, 20 and more ...

Some test
Hi, today I set up a very simple scene just to test some materials and experiment with Kray. There are some settings I don't understand well, this is my first attempt because I always used the default lw engine. Here are the 2 super basic raw renders, no post production, no tone mapping, just the tw...

Re: interior render Wip
Because I use this non stop it this just matter of seconds to setup for me material without rendering (but this is normal when you use non stop same system - you just get use of it) I tried a fast modded setup in some variations: wood, leather and chrome and it seems work very good (usually for thi...

Re: interior render Wip
ok let`s start from basic surface. (cut) Well, that's REALLY interesting. In my experience I always thought that the fresnel node in lw requires a real IOR value, i.e. like based on this reference http://refractiveindex.info/?group=METALS&material=Copper I tried many times to re-create the angl...

Re: interior render Wip
Well, I do not use gradients - only fresnel, all materials has it. Also I watch many renders from Maxwell because this render engine is very accurate (of course is too much overrated with physic - is not necessary use that strong physic in renders!...and too slow to do something with sense) SO I tr...

Re: interior render Wip
Incredible result!
Janusz, what do you mean by nodes according to physics? I mean, I know about energy conservation etc, but how do you find the right curve for gradients/fresnel and others, is it all 'by observation' or you got some real references?

Re: Clear-Coated Material
Thank you Janusz, maybe it's the demo, some of the free scenes downloaded from the Depo are in fact a bit different in rendering or in some case completely crash Layout (ie hotelroom that doesn't work at all) Anyway I'm considering the purchase, but I need reliability in the demo to make my decisio...

Re: Clear-Coated Material
Try this idea Any idea why when I try to start a render with this material, Kray keep crashing Layout? It's a pretty simple scene, just an object. It's my first week with Kray, but I'm experiencing many issue with node based materials. btw I'm using the demo version v2.4 and LW 11. It should not. W...
