glass material

Post by tiktane358 »

I find that Kray have same problem that LW about time render when there is transparency. Kray use 24 bounced... Is there a trick like Maxwell's igs ?
Architects love transparencies. Need double side ?
In a render I didn't notice time difference with 1.0 and 1.6 refraction material for thin safeguard. ?
ah, last thing : I have problem with Kray panel buttons and pop ups, sometimes they don't respond at the first time.

I'm not sure what you mean "same problem that LW about time render". Transparency is all about raytracing refraction...
I'm not familiar with maxwell's igs either.

Could you elaborate more about this?

I mean that every time I want to make renders with lots of glass material I'm very sad because I can't manage to have good render time. Perhaps true for every softs, but I use LW.. :-)
igs material (if I don't make a mistake) is a transparent material that match architectural windows renders : no need absorption,dispersion, refraction,... just see that there is a glass and have a bit reflection.

Well there's only one thing you can do about that and that is to limit the number of recursions. It's on to-do list to implement number of recursions spearately for each ray trace type so you could have separate bounces for transparency, another for reflections and another one for GI.

In my scenes I use simple glass material with incidence gradient on reflection and transparency and a little bit of color filter... It works good IMHO.

"number of recursions separate for each ray trace type" would be a dream...

Kray panel buttons don't respond at upper half

tiktane358, I've noticed that the problem of Kray interface buttons appear to be not responding is due to the internally overlapping "Kray.ls" separator line (ctlsep) and the subsequent line of controls/buttons (ctl)s (buttons/pulldown/checkbox/etc).

look for the lines in Kray.ls, for example :

c_sep_gen = ctlsep(0,0);
ctlposition(c_sep_gen,10,ypos+ysize/2,420,19);ypos=ypos+ysize;

changing the height value of 19 to 1 for every occuring separator line (ctlsep)'s ctlpositions entry will fix the overlapping appear to be "respond at the first time" issue.

Thanks for that tajino! We'll try to fix it in next release.

You are welcomed Jure, this problem has been bugging for the ages since pre 1.6 till now, that only now i've some time to dive into G's Kray.ls

and Thanks a lot for your tutorial on 1.7, it is very very helpful!! :D

this is my glass
it walked me about this near good quality the time of renderingu it would be short
and I will admit that I placed long Kray they would reach this

my English it is not good
sorry :lol:

I greet

Hmm... Did you use photonmapping for this since they tend to be faster with transparent things? Tell us some more of your settings and on what cpu.
It's rather splotchy and it should be able to tweak it much much better.

and this glass with MODO
it when will be service node editor by Kray
this realizable will be in LW
to get such quality now hard

Why would that be hard and what was the rendertime for that modoscene?
Upload the lxo and il convert it to lwo so we can judge by the same scene.
