Re: This is so Awful!
are you using DR?
Re: This is so Awful!
No! Its only one computer!
Re: This is so Awful!
you used quasi montecarlo right?
cause that happened to me once and i fixed it only by switching to light cache
Re: This is so Awful!
These are comercial renders, first I was receiving Null material, So I decide to fix all textures and geometry, I fix the problem but the this black horribles squares killing my job! ???
Re: This is so Awful!
No its light cache and Irmap Omar!, I am very upset, Im losing gold Im losing time my friend.

We don’t have quasi montecarlo, we have Deterministic montecarlo.

Re: This is so Awful!
if you move the camera, does the black square stay in the same spot? or does it move? If it moves around like a piece of geometry in the scene, then that may be exactly what it is. If it is always in the same part of the render, no matter where you move the camera, then it’s something else entirely.
Also, could you give us your system info? Especially the version of VfS that you’re using? There are HUGE differences between 1.05.30 and 1.48.66 or later, and rather large differences between each of the updates to 1.48.66
Re: This is so Awful!
Does squares are not visible to the camera, it appear in the last threads of the buckets.

Im using version 1.05, and my computer specs are: sony vaio 4gb ram and dual core t4200 2.00ghz

Re: This is so Awful!
This has happened to me before now. It seems like one bucket failed to render. I re-rendered and the problem didn’t re-occur, so I could only put it down to a glitch in the computer itself.
As for the render times - wow! That might be down to lots of reflective surfaces i.e. glass reflecting in glass ad infinitum. But that would kill me!
As per the manual (!), I use IM -4,-2 (for drafts) and -3,0 for final, also increasing the HSph from 80 to 100 and samples from 30 to 60 for final renders.
Good Luck

Re: This is so Awful!
Thanks for that information, and yes a lot of glass in the scene, And im doing the render again let see what happen. 
Re: This is so Awful!
Hello DaveReyes-
I had this happen to me at SIGGRAPH while presenting. It seemed to be the hardware and not the software. I solved the problem by doing a region render over the non-rendered or black area. Hopefully this helps.
Best regards,
Corey

Re: This is so Awful! AGAIN!!!
ok, I’m guessing a bit now!
Maybe you are running out of memory (with so much going on in your scene - glass etc.) and maybe other applications running.
I would try closing everything down, re-boot your machine, load only SU and try re-rendering.

Re: This is so Awful! AGAIN!!!
region rendering I think is something that we brought over to V-Ray for SketchUp in the 1.48.66 release. I could be wrong, memory’s a bit fuzzy.
Fernando looked at your scene and said that you have some less than optimal settings, the bucket size for instance is huge! So if that bucket requires a lot of computation, and your computer can’t handle it, the bucket will fail, leaving an ugly black box. Try a smaller bucket size.
Re: This is so Awful! AGAIN!!!
How can I manage the buucket size, and of course having good quality, To be true I am not a master inn settings but I know that Fernando can recommend a batter setting.
Re: This is so Awful! AGAIN!!!
Hi Dave
You have to go to the system tab and change the “width and the Height” of the region bucket. You can use 32 for both. Also your anti-aliasing is extremely high, used 8 or a maximum of 16. There no reason to use more than that. I’m rendering your scene in my two core computer with the same output dimension and with the new version, the render time was 48 min. Why you don’t change to the new build? It is pretty solid and with a lot of feature and a fast parsing time.

Re: This is so Awful! AGAIN!!!
Can I demo the new version, Y voy a hablar aqui con los arquitectos para que compremos la nueva version pero si antes me gustaria ponerla a prueba, hey Fernando se que quizas este molestando mucho pero podrias compartir el visopt que usastes para la escena, Estoy sorprendido 48 min. si que me estoy quedando atraz amigo. De ante manos te agradezco muchisimo de verdad que ustedes tienen un excelente equipo en asgvis, y estan al servicio de nosotros los usuarios.
Bendiciones Totales.
Re: This is so Awful! AGAIN!!!
Hi Dave
Te la voy a enviar por email la escena completa. Asi podras tener todo. La version nuevas es gratis para los que ya tienen un numero serial. Asi que no necesitas comprarla.
I’m going to send you the whole scene by email. So you can get everything. The new version is free for old user, so you can use your old serial number . You don’t need to buy a new serial number.
