Title: refraction glossiness
Post by: ondrike on 2013-03-05, 16:31:39

Hi,

I´m not sure if anyone already mentioned this, but glossiness refraction doesn´t work in latest daily build. I´ve tried couple examples and still the same result.

in alpha v3 glossiness works

Ok, glossy work, but strange as it.

weird.. could you upload your scene?

works for me, what build timestamp are you using?

doesn't work in latest legacy build, anything below 1.0 refraction glossiness breaks the shader

I modify my old post!
New HD cache is also used to clean the reflections? Render time is now significantly more!

I´m using build from yesterday in max 2013 with win7 64bit and doesn´t work for me at all.. I´ve tried PT+HD, PT+PT and nothing

scene posted by polymax ended up with same result

Mysticism! My "Build timestamp: Mar  4 2013 23:09:48". You can share yours scene, I will test it?

ok, problem solved, and guess what :D I just restarted max :D

I don't even...

LOL :D:D... Anyway, refraction glossines doesn't work for me no matter what I do. And if I'm not using reflection, only refraction and set refr. gloss below 1.0 the shader is just black... :( can you update legacy build, if this isn't happening in regular newest?

Title: Re: refraction glossiness

it's updated

I don't know that you update, but bug remained.
latest DB
PT+HD
glossiness 0.49

Refraction Glossiness is working again in mar 6 2012 build also I have no more fireflies with max sample intensity 10 :)

Title: Re: refraction glossiness
Post by: ecximer on 2013-03-06, 12:00:24

Why, if the max intensity change as a result of changes?

Title: Re: refraction glossiness
Post by: Ludvik Koutny on 2013-03-06, 13:03:10

0 means disabled, therefore not limiting max sample intensity value....

Title: Re: refraction glossiness
Post by: ecximer on 2013-03-06, 13:21:28

that is, it is not a bug?

Title: Re: refraction glossiness
Post by: Ludvik Koutny on 2013-03-06, 13:38:13

0 means disabled, thus equal to unlimited number - infinity...  Any value larger than 0 activates max sample intensity parameter ....  so value of 1 will introduce extreme clamping, value of 10 will clamp samples normally, and values above 10 will further reduce sample clamping up to the point where value get's so high results will be similar to max sample intensity being disabled (set to 0)

So yes, this is a feature...

Okay, I understand now, thanks for the clarifications :)!!!
But glossy now do not work correctly with interpolation parameters by default!

Yes, but the problem you observe is probably not related to max sample intensity...  If you see those blotches in glossy refraction, problem will be somewhere else.

Title: Re: refraction glossiness

0 disables it because the spinner cannot go to infinity. So I set it so that 0 == infinity.

It is not related to the HD cache glossy problem, but it is also strange that the value o 10 clips it so much

Fixed

Hurrah!
