Glossy Problem

[samuel_bubat]

Hello,

I just noticed the following behaviour of glossy reflections.
On some parts, the object looks like beeing flat shaded.
Is there anything that can be done about it, or anything I´m doing wrong ?
(Just a standard Vray material with reflections and glossiness)



regards,

sam

I have the same problem with anisotropic "on" :

Strange squares into reflection glossiness...

Vray 1.5SP1 64Bits + max 2008 64Bits...


Vlado I could send you a sample scene as soon as NDA fall in the next few days...

Best regards...

You should post your scene...

It´s just a test scene... A Plane with some procedural material applied and a glossy sphere
(Vray material out of the box diffuse black and glossy reflections).
I tried nearly everything.. and the only thing that solves the behaviour is switching to
phong shading.
It happens under any circumstances I tested. Vray Sun, HDRI, default lights, secondary GI
QMC or Lightcache.. different cuttoff parameters.

I don't know if you speak about the same problem I have...

Look at the sphere's base the reflection is very strange. Some squares appears...

PS : I know... my english sucks !

Hello Vlado...

Very good news... do you plan to add this fix into SP2 ??? If you add it I can wait until april 20th

Best regards...

[vlado]

Yes, there is a "Soften" parameter for the BRDF in SP2 which helps to deal with such issues, until we roll out the V-Ray BRDF.

Best regards,
Vlado

So I will wait for SP2 if this will be released in just a few weeks.

But thanks a lot for the offer !!!
I don´t know another company where this would be possible !!

Best regards,
