Working with Redshift’s AOVs in Cinema 4D

[@spIette]

Omg, I had been looking for the Material ID in the new Redshift everywhere. Thank you so much.

[@joekunitz620]

You fill in a lot of pieces that other tutorials glossed over thank you

[@erikmder11]

It might be worth noting that the way this was presented, it's not obvious straight away that this is working in Linear sRGB workflow, not ACEScg (as is default on Redshift). You won't be able to see it composite correctly in Photoshop this way without correcting for it using the OpenColorIO plug-in

[@travisvermilye]

Thanks! This is great!

[@marvelousdecay]

Glad you like it!

[@driggsy]

Awesome tutorial! Thanks for this

[@mwasifanjum]

Great TUT! Just needed this to know!

[@AmbujKoshi]

Really helpful! Helped me on my current project. Thanks Dimitris!

[@marvelousdecay]

Great to hear!

[@leepowers1316]

thanks dude.

[@massimobaita7178]

Thank You very much, Dimitri's!

[@fancyvideoyo]

Just getting into Redshift and what a differrence your videos are making! Thank you

[@theChefnut]

Photoshop wont let me copy the shadow layer and paste it on the levels mask. It just pastes as a new layer.

[@davidcowell6141]

did you ever figure this out? I am having the same issue!

[@jasonwasher5637]

@@davidcowell6141 Same here. Ive never seen that done before.

[@alvaromatasferrer5841]

same here, getting crazy!

[@ferdaramos]

You need to Alt+Click on the mask, and then paste the layer selection you’ve copied!

[@gabrielamelina9709]

@@ferdaramos still cannot do it 😓

[@evolnull125]

Shadow layer that's what I need. Thanks

[@darrynrogers204]

Great video. Thanks Dimitris.

[@tsorrell1]

Great video! Easy to understand and well explained.

Thanks so much for the tutorial! Saved my butt! :D

Thank you so much !

You're welcome!

[@cfshhhp7800]

So good!

[@steilvorlageDE]

Thank you very much. Did you recognize that spring-constraints are working strange, if you activate the "Motion Vector"-AOV? Seems to be a bug.

[@marvelousdecay]

Haven't tried that but I wouldn't be surprised if there was some sort of bug. Definitely post the issue on Redshift's forum for the developers to see and hopefully fix.

[@daniburton4190]

Hii great tutorial!! Thank you so much for your time and dedication. Btw it would be awesome if we could get a separated layer for the Post-Effects. Do your know if there's any posibility?

[@davidkerman1732]

how do you handle stuff like pyro and other volumes?

[@gabrielamelina9709]

how do you copy paste the shadow layer into the mask layer??

[@marvelousdecay]

Copy the shadow layer and then to get in to the mask, then while holding down the option key (or alt for pcs) click on the mask. That will send you in to the mask where you can paste the shadow

[@timaging]

How do we get material passes? This was present in nodes before and I can not find this in redshift

[@DynamicPhil84]

Great tips Dimitris! One thing that still confuses that I can never seem to figure out with multi-layered PSD files: if your object/s are on a transparent background and you render out an alpha channel to the layered PSD file, how do you then access that alpha channel in After Effects? Since it appears as a custom channel in Photoshop, it is not automatically selected as the alpha in After Effects.

[@marvelousdecay]

Hey Philip. After effects should read psd alphas automatically. Just make sure that your alpha is not just another layer in your psd file but it lives in the "channels" section. That should do the trick.

[@DynamicPhil84]

@@marvelousdecay thanks for the response. The alpha is in the "channels" section, but maybe the problem is that there are multiple channels when a multi-pass PSD is exported from C4D? When I go look at the channels tab in Photoshop, I will see the alpha as a channel, but there is also the default all white channel. Maybe if I delete that all white channel so only one channel is left instead of two, that will fix the issue?

[@DynamicPhil84]

Actually the real problem here is when I am dealing with a PSD image sequence. It isn't a problem deleting or isolating a channel in a single PSD file, but if I have hundreds of PSDs in a sequence, I can't manually delete channels or layers from every single file.

[@marvelousdecay]

Yeah the multiple alpha channels might be an issue. I would suggest using another file type for image sequences since psd can be big in file size especially if you keep the photoshop compatibility option enabled. Try OpenEXR. You might like it more.

[@DynamicPhil84]

@@marvelousdecay Yeah typically I use png image sequences but it gets to be a hassle with one sequence per render pass. Importing each sequence into After Effects is kind of a chore. OpenEXR is the best format but huge file sizes, unless I am using unnecessary settings. I only render out at 16 bit, not 32.

[@adamfilip]

how much do AOV slow down rendering?

[@marvelousdecay]

I haven’t noticed any difference in rendering time. Maybe a second or two extra to save the additional files?
