Lighting render passes save out for Animation?? Tweet

[Bendbox]

Hi Everyone,

The Lighting Render passes are hugely helpful for still frame rendering and composting -- however, I'm currently working on an animation (with Bongo) which has several RGB LED's in various areas in addition to the main lighting. These LED's will cycle between orange, yellow, and white. What I'd like to do, is have Octane save out the Lighting Render passes, as well as the main beauty pass, all during one animation run. So, instead of just a 100 frames with only the beauty pass, I'd also get 100 frames with just the Orange pass, 100 with yellow, and 100 with white. Then, I could composite all of the lighting passes in my film editor and create a lighting setup where the various LED's are cycled on and off to be timed to music, or any other variation.

Right now, the only way I know to do this, is the run the animation set with each light separately. So all in all, it's running the same animation over 4 times to get the beauty and the 3 LED variations.

Is there any way to have the various rendering passes save out along with the main beauty pass so the animation only has to be run once to get everything?

Thanks,
Ryan

hi,

not sure if this works but you might give it a try...

you could maybe copy the led lights and place them at the same spot (or if you get problems very very close together...) assign each light to a different light channel , the emmiting lights have to be 100% invisible. combine this with a fake light which is white, 100 % visible and not emitting. So you would end up with a beauty pass with white lights and 3 light passes with colours ... these might be applied with a working layer effect in post...

just an idea...

Hi V-cube,

Thanks for the reply, but I'm not understanding how this would help with regards to animation? I'm not just doing a lighting animation, the camera and objects in the scene are moving as well. The lighting passes are not saved out along with the beauty pass when each Bongo frame is rendered, so I'd still need to run the animation over 4 times to get all of the needed frames for the lighting scenarios.

I know I can use a Native Rhino material and animate the light itself, which does work, however, it's impossible to sync the lighting changes to music. So, in the end, having 4 separate animations to composite in the film editor is the way to go. I'd just like to not have to run the same animation over 4 times to get all of the frames. The beauty pass and 3 lighting channels are all calculated in one render for a still image currently -- it would be great if this information that is already available for still images could also be used for an animation.

Thanks,
Ryan

You could try exporting the animation to OCS/ORBX and then rendering in Octane Standalone, which will allow you to render out multiple passes at once.

Excellent, I had no idea that the Stand Alone had this capability. Thank you. Any way to incorporate this feature in the plugin in the future?

Rendering animations in the Rhino plugin relies on the Rhino render panel (rather than the Octane Viewport) - and the Rhino render panel does not have the facility to save to the multi-layer EXR format needed to do what you are after. So I don't think this could be added to the plugin for animation rendering. It is already present in the plugin for single frame rendering (it's the Save All Enabled Render Passes To A Layered EXR File button on the Octane Viewport).

Ok, thanks Paul, appreciate the help, as always.

Hi,

I'm working on an animation setup and run in the same problem of multi channel output. Couldn't the Octane frame buffer not be used for the output of several channel png files? For example Vray for Rhino doe's it on this way, it stay on the own frame buffer.

When you render a Bongo animation via the Rhino render panel, it is Rhino that is saving the frame buffer to png/jpg, and not Octane - so I don't think this would be possible.

Paul, I'm wonder how you don't understand me always.

Conclusion: I want to say, Vray for Rhino can do it and it's done with the VfR frame buffer. And so my request is, why shouldn't Octane go this way and use the own frame buffer? Would help to keep the workflow simple and direct.
