pale/dark DR buckets

[tricky]

I had a similar problem recently and it turned out that there were different service packs installed on my workstation and the render nodes. That gave me bucket differences too. Could this be the case?.

Don't think so. As far as I know everything is the same. Here's another project exhibiting the same problems:-



Its just my local machine cocking things up. Any chance I could send this file to Chaosgroup to figure out what's happening?

Most certainly you can Email us to vray@chaosgroup.com to determine how best to send it.

Best regards,

That's weird. Its almost as if your pc can't see the HDRI map, but the slaves can, which doesn't make sense. My guess would also be different service packs or vray builds.
Also check that ALL machines have the decimal setup as a . (point) and not a , (comma)

In Windows 8 they decided to change the default to comma instead of point

Probabely that´s not the problem you have but there is also one other thing that makes only your workstation render different.
If you have an object with a modifier stack selected and any other modifier than the last one in this stack is selected, while show end result
is turned "off" it will render different only on your machine. For example when you have a sphere with an uvw map, the sphere is selected
but in the modifier stack the sphere below the uvw map is selected. It will render just on your machine without the uvw map while all the slaves
render with the uvw modifier.

Hi Richard,

We have send you a reply via our ticket system with details about how to upload your files.
Did you receive it?
Maybe our mail has been lost.

Sorry about that. I did upload the files but then the problem went away. However, a short while later (that same day!), when working on the same scene, the problem re-surfaced. I was in the act of updating our ticket, but we have found it is happening more and more in pretty much all of our projects. I believe it is related to using solidrocks, but I can't be absolutely sure. I have since started using a different method for rendering which is far more manual - using LC and BF, and for the moment, the problems seem to have gone away.

When I have more time, I will try and follow this up, but my gut feeling at the moment is that Solidrocks is doing something weird that freaks out locally rendered buckets.

I had exactly the same issue and it was because I installed 3dsmax 2014 sp3 on my render farm and forgot in one pc; installed it and voila´.

I have just one other node. My server and client render slightly different densities with DR.

I've spent an entire day trying to solve this. I've read about everything I can find on the web and everything here:

1. Both machines have the same versions of Max 2014 and V-Ray 3.0
2. All paths are UNC
3. All textures are rendered by both, just one is a tad lighter.
4. Both machines are Administrator and have access to the same mapped network drive with the same drive letter for both machines.
5. The anomaly shows even if I turn GI off. So it's not Light Cache.
6. I'm not pre-calculating anything.
7. I've stopped and restarted the Spawner.
8. The anomaly shows up in almost all main passes: Lighting, GI, Lighting, Reflection, Diffuse Filter,

I just can't solve it. Anyone else have any crazy things to try? I think I've tried them all.

Same problem here, everything has been working fine for a good while but suddenly this has started happening again (have imported some objects and textures from an older model I made a couple of years ago, but have updated all paths etc.).

[RobH22]

Yea, I'm not sure either. Maybe it's a bug in V3.

Turns out this is not a DR problem this time for me - it happens when rendering only on my local machine also, and seems to be coming from the Vray Dome Light with HDRI in the scene. have tried different HDRIs but same problem. Replaced Dome light with a Vray light plane and the problem doesn't occur. Also seems to be scene specific as other files are ok. Very odd!

[RobH22]

Doesn't solve it for me. I removed the Dome light and HDRI that I too had and I still get a faint density difference. In fact, I removed all V-Ray lights and then added in a new Plane light. I still get the problem.

Which is the V-Ray version that you are using? Is it 2.x ?
There is an issue with the Dome light sampling.

Make sure that you have installed exactly the same 3DS Max service pack on all machines.

Would it be possible to post or send us the scene file to our support mail to try to reproduce the issue in our environment?

[RobH22]

Tashko, I'm going to do a few more experiments and then I'll get back to you. I'm working on a project right now and I'm not having the issue. It appears to be intermittent. Last week I could not get it to go away but right now I'm not seeing it. Odd. Nothing has changed. Both machines have the same Max Service Pack.

Once it comes back I'll let you know. I'm also going to try to reproduce it. Before, I couldn't do that because it "always" happened. So, I was spending my time trying to stop it. Now that it's gone, I don't really want to make it come back, but I'm going to see if I can.

Thanks..
