Glare effect not applied to EXR when saved out of backburner

[tmbarker531]

I've been struggling to figure out why, when I send a render using backburner, the saved out EXR does not have the glare effect applied. The bloom effect is there but not the glare effect. When i render the image locally they are both applied correctly when the render finishes and when i save the image out from the vray frame buffer as an EXR it works as to be expected. Is there some extra render element that I have to add for this to save through backburner? The new "effectsresult" element that is automatically added to the vray frame buffer when rendering with bloom and glare is not an available option to add in the render elements tab. Any help would be great, thanks! Using max 2015 + backburner and vray 3.50.04.

I've just tried it - looks just fine. Can you send me a sample scene at peter.matanov@chaosgroup.com ?

Is it possible that you are using an image for the glare effect and the render slaves can't find that image?

I had some similiar problem with it and when I turned off hardware acceleration it was ok.(the rendering nodes dont have to have graphics cards) Maybe it doesnt recognize the hardware or doesnt switch automatically to cpu ?

[vlado]

Hm, this shouldn't happen. The render nodes have no graphics card at all? Do you get any errors or warnings in the V-Ray log? I think in that case both bloom and glare would fail, and not just one of them.

Sorry I didn't report at the time but I was in a hurry, I'm only speaking from memmory now and throwing it as a hint for a possible solution. My render nodes have some old primitive graphic cards and I guess they cant be used for acceleration but generally speaking render node could have no graphic card at all with no problems, its just needed for maintenance anyway, right ?

We had that case just now. I sent a job to the farm, the only clients that generated the glare/bloom were the artists workstations, which have GPUs. Our farm doesn't have any GPU (really), and they didn't generate the lens effects. I just sent it again via backburner, but with hardware acceleration disabled for confirmation. Didn't think of that, thanks for the hint!

mine does the same; I have old graphics card on the nodes and I have to disable hardware accelerated to be able to calculate glare

[vlado]

I have old graphics card on the nodes

Can you tell me what kind of GPU it is? Ideally we want to fix that, but we will need some way to reproduce this here.

mostly, nvidia quadro 600

I haven't yet tested to see if this fixes it but it sounds like this may be the issue. I made sure to check and I am not using an image for the glare effect. This explanation would make sense for why it works fine when the image is rendered on my local machine (even with distributed rendering turned on) but when the backburner server is hosted on one of the machines in our render farm- the problem arises. We use render nodes made by boxx- here is the link: http://www.boxx.com/Files/Files/Prod...download=false it says the graphics card is ASPEED AST2400 BMC which seems like its barely a graphics card.

When hardware accelerated is checked is it only using the graphics card of the machine that has the backburner server running?
