So, I was struggling against some light leaks and I wasn't able to find the problem: geometry, lights and materials were perfect... but eventually I found an unexpected solution! I don't know if this is documented or not, I don't remember read anything about that, but here's what I found out: If you...

Thanks, but if is something wrong please post immediately - but before check twice and send me synthetic small scene with bug (if possible). It was a lot changes in LW2015 and can be we missed something and also are some bugs in new Lightwave and G. did not make enough bypasses for temporary avoidi...

Just a small update: I'm trying the 2.58 and it's working fine with LW 2015.1, all problem solved.
Good job!

OK, thank you Janusz, I'll stick to 11.6.3 for now.
Helpful as always!

Hi guys, any info about compatibility issue with kray 2.57 and lw 2015.1? I'm experiencing a problem I can't solve: if I try to load an old scene, say a lw 11.6.3 scene, it works ok BUT if I try to use the Package Scene function (in File->Package Scene) there is no way the new scene works in Kray: i...

Here we go, the scene for those who want to do some experiments. Basically it's just a transparent node with 100% refl/refr blur. I don't know if the grad thickness node output is connected in the right way, as Janusz said it's a strange node to control and sometimes doesn't seems to affect the mate...

Ok, here's my attempt. It's far from perfect (it's just a super fast setup actually), as you said the thickness is difficult to control.
1 is fake sss
2 is fake sss + double side
3 is normal surface with just some fresnel

Ouch...
What do you mean by double translucency? Double side surface + node setup with different translucency for poligon side? I usually do that with different materials using spot info poly side and switch node, I'll give a try
Btw, do you thing kray 3.x will have this kind of surfaces?

Hi guys, I know that the lw SSS nodes don't work in kray: any ideas how to make a fake but convincing sub surface scattering for something like rubber, wax, plastic and similar?
I was thinking about the thickness node and transparency + translucency, anyone who managed that in a good result?
Thanks!

Ok, I'll try this!

Meanwhile, I'll be waiting for your nodes, I'm really curious because for now I'm not getting the best (yet) from kray, and I still using the lw engine for production :-/

Hi guys, do you know if the carpaint node works well in Kray?
I'm getting strange results, and it's super (super!) slow to render...

The biggest innovation in my system Nodes is Multiplying layers and injection system. Will explain it in main time.

I'm really curious about this injection system

Yes, for sure it's a strong pp that make the deal with this images. PP a part, I can do something really similar in lw but not in kray, so for me is a good benchmark to work on and learn kray. Ok, this is the super basic setup, all reset, just a basic tonemap, so I can better understand one piece at...

Hi Janusz, thank you as always for your answers. So, I moved the light outside but behind the object, but the problem is still there: the leak goes away only if I set the lamp translucency = 0, this fix the problem with light leak and general splotches and the render looks perfect. In your experienc...

Hi guys, it's me again with a new render for you, and some problems to solve. As you can see, I'm going on with experimentation in kray. This time is an old scene I made in lw time re-interpreting the famous work of Alex Roman: nothing new, but a good start point for common problems in archviz. Unfo...
