secondary output

[paulDryzen]

Hi,

would it be possible to add a secondary output to the rendering?
For example a compressed tif/png/jpg together with a multilayer EXR?

seems like that would be a pretty straightforward convert at the end of your render scripts. (and also, a really good idea!)

hey shade,

sure that can be done with a convert script after the rendering is finished. But the script will fail if one of frame is missing. Due to some limitations in Royal Render (we are still using the old version). RR cannot check multilayer EXR files. RR thinks that if there is a frame, everything is allright. But sometimes this frame is only 1kb big .
With a secondary output as a jpg or tif RR would be able to check the rendering. The other good thing is, the network traffic would be a lot less, because checking a sequence with multilayer EXR files is I think a bit more stuff than just a simple compressed tif.
If the renderer could write this file after the exr file that would be great!

ah gotcha, we use deadline... but we also render to VRimg and then per frame a script kicks out the zipped, multichannel exr. (I'm going to have our pipeline TD add a jpg output as well).

Since we switched to vrimgs we almost never get bad 1k frames, we used to get them ALL the time when we rendered straight to exr. I think essentially, internally it creates a vrimg in memory and then writes the exr or something, and if something goes wrong, the exr writing bails at 1k.

This does occasionally happen when manually using vrimg2exr, but at least you have the full vrimg and dont need to re-render the frame. Just reconvert.

Not sure if this will help you, but I thought I'd share!
