[Deadline] - Anyone here have experience with visible tile seams?
show user profile  9krausec
I'm having an issue with Deadline v7 (Thinkbox) running Maya/Vray.

When I region render, the tile seams are visible at times. Missing assets are not involved in this. The issue only occurs when region rendering with multiple slaves.

Has anyone here, with Deadline experience, ever had this issue happen to them consistently over multiple scenes? I've submitted a ticket with Thinkbox, but I'd wanted to ask here to see if maybe one of you have been in this position before.

As I've said, this issue has nothing to do with missing assets, maps, textures, but has something to do with Deadline (I believe).

If you believe they will be of assistance.

This looks a bit like a problem I used to have/ when I was rendering regions in vray I used to get a different result (usually darker I think) than when doing the entire image. My solution to that problem was to never region render again :-)
But I have no idea what deadline is

well that sucks to hear. This might be a Vray problem after all then..

Deadline is created by Thinkbox and is a render job management system.

What it's doing is cutting up my render area into tiles, sending each tile to any given slave for rendering. Upon completion, that slave return the tile to the workstation. After all tiles are done rendering they are assembled by Deadline.

So, in essence it's a bunch of region renders I suppose to Vray. Your comment actually helped me out considerably since I really didn't even know what to research. I'm going to look into this problem with darker edges with region rendering.

Weird thing is that I've never had an issue region rendering with Vray/Maya, but then I've never ran through Deadline before.

Thanks much.

@Marko - good call on the screen grabs.

Well joelr. You were one helpful guy today. Got me thinking a bit differently with the render regions so I did a GI test and guess what....

GI on / GI off

Still have no clue how the f*ck to address this, but at least I know what the problem is now.

Personally that is something I would bother fixing in post(After Effects or photoshop) rather than in max/maya
and it looks like some kind of artifacts because of the graphics engine not taking into consideration the whole scene in the illumination calculations while rendering an specific part of the scene.

maybe, just maybe, try scaling everything down and zooming in?

And that's the dilemma... I do about 2 thousand of these renders annually (on top of animations and other administrative work/IT support).

Fixing this issue manually 2k times over a year isn't an option.

which version of deadline do you have?
7.2 has an option to do jigsaw regions, that might force the engine to take more of the scene in consideration for the illumination.

I'm running the latest version of Deadline.

I've attempted both tests with tile rendering and jigsaw with the same results...

That being said, I'm currently rendering tests actually using the padding which I think is going to do the trick. I'm also going to be chatting the Deadline support to see if there is a way to calculate the GI on one machine and distribute it to the others (so they all have the same GI).

Take it it's not an issue with GI files being accessible?
Have you tried a render test just using vray without deadline?

Could also be plugin related, any plugin that is contributing to the material and not present on the slaves

GI files are accessible since each slave is rendering it's own GI which is the problem. Vray DR works fine, but the GI is being rendered on a single machine. Eliminating the issue.

My padding tests are almost done rendering. Will let you guys know what results they yield.

One of these has "padding" turned off and the other set with a value of 50... I'll let you guess which one because I sure as shit can't tell the difference.

Attempting Brute Force/Brute Force solution to see if that changes anything. I've been using BF/LC for my last few tests. I'll get to the bottom of this and spam this thread with troubleshooting attempts until I figure this out.

so, what resolution are you rendering these at? the reason i ask, i assume they are larger than 4k or something, since u are breaking them up with deadline (opposed to just rendering them on 1 machine)

this most definitely resembles what happens in vray when you are to "region" render a section of an image multiple times

for instance, im sure this wouldn't happen (i dont think this would happen) if you were to just render the image as is (ie, on a single machine in 1 pass). which brings me back to my original question..

your solution may involve baking gi maps?

@Digs- Yes, baking GIs would be a potential solution. I'm rendering these at 3500x3500 which is a standard catalog render for us.

Our render farm is sort of crap-tastic. I'm glad we have one, but it consists of 5 machines at the moment. 3 of them with some decent xeons (16 cores total) and 2 of them with 8 cores. I want to be able to use all of them on one job as I don't want the 8 core shits to get hung up and take years to kick out a render.

I'm going to try to avoid baking GIs though as it would be an extra strep in the process. Trying to make this as efficient as possible. Monday I'll talk with Thinkbox/Deadline tech support and see if they can come up with a solution (I'm sure there is a solution for this).

As of now, I'll be using Brute Force/Brute Force as those renders turn out great.

Fill you guys on in on Monday if I hear from Deadline support.
