CINEWARE supports the multi pass feature from Cinema 4D, which allows you to render your movie or image in individual components rather than that final rendered single image. You can render other things, like the shadows, the refractions, the specular values. As individual passes. And that (INAUDIBLE) makes it easier to do post production on the more add effects in a compositing application like After Effects. Now, you have several ways of using the multi pass option.
If you haven't set up your multipass options in Cinema 4D. You can still use the multi pass workflow. And you do that by clicking on this button here. And it allows you to set individual multipasses. And you'll see here, I've already selected the shadow pass, and it changes my render so that it only renders the shadow pass. So its only showing me the shadows from my Cinema 4D file. If I click on it again, and choose specular, it will only show me the specular values.
If I click on it again, and choose diffuse, it will only show me the diffuse values. Now this is quite useful. It's basically rendering these passes on the fly for me. And if I hadn't set up my Cinema 4D projects with multipass. This is a handy way of just quickly accessing a pass. But it's kind of tricky because if you want to combine passes, you have to duplicate your layer and then open up the effect on the second layer, decide on which path you want here so maybe I want to combine my specular with my diffuse path. And then I would have to set up blending modes to blend them together, so may be use add mode to blend my specular values with my colour values and then if I wanted shadows I would have to duplicate again.
And have you changed the one in the middle, to Shadow, and then we probably want to compose at that using something like Multiply or Darkened mode. And you'll see how we start to combine passes together to create our final image. So this is basically how multipass works. You're combining different passes together. >> To create your finished image. And the powerful thing about that is if I decide the shadows are too dark.
I can just open up the Apaste Settings and just reduce the apaste of the shadow layer in order just to drop those shadows down. So, you'll see how much more flexible it makes your 3D rendering. You can adjust the shadows. The highlights and add effects to all of these elements as well, reduce the specular values there. So this is how multipass works and if you haven't set it up in Cinema 4D. This is how you would work manually by adding individual passes, but there is a much better way of working.
So what I'm going to do, is I'm going to revert this project back to the saved project. If you've been playing with the project too, you can do that also. And what I'm going to do is select the CINEMA 4D file down in the timeline, and hit Cmd > d, to open it up, in CINEMA 4D Lite. And in the render settings, if we go to Edit Render Settings. You might remember how to set up your Multipass options, if you've gone through the tutorials that teach you how to do that in Cinema 4D.
If you haven't, basic refresher, you switch on Multipass. And then you add the different passes here. Now what I can do is I can add all the ones that I want. So I'll add Diffuse. I'll add specular, I'll add reflection, and I'll add shadows. Okay, all I need to do now is just save that file. So I'll just hit command s control s on windows. To save the file. Once it's saved, I'll jump back to After Effects.
And now, if I open up my (INAUDIBLE) effect. Just double click it to open it up in the effect control panel. And we scroll down. Now, sometimes, this doesn't activate immediately. There is a checkbox here, which should update when you change those settings. If it doesn't, a quick reset of the effect usually will reset it. Now, if I do that, I need to go back to standard draft as my render. And then come down here. And you'll notice that this button here has refreshed.
Basically, what this allows me to do is click on Cinema 4D multi-pass. And instead of creating individual passes. I can say, give me my defined multi-passes, and then all I need to do is add Image layers. And it will add all of those layers for me. And if we have a look down in the timeline, I'll hover over and hit the accent key. You'll notices it's added my reflection, shadow, specular, and diffuse values that I selected in Cinema 4D. And it's genius like, applied the correct blending modes for them as well.
So rather than have to do it individually in Effects, it's much easier if you just set it up in your settings in CINEMA 4D. And then all the composting will be done in After Effects for you. Now if we got to standard final, all that's going to do is change the settings on one of these effects now notice that we have, now four layers with four effects on them. So by changing the renderer on 1, your not changing them all. But if you click on the Apply to All button That will change the effect settings for all of the effects in there.
And you'll see now I'm ready to go, and make adjustments to my reflection shadow specular and diffuse values. And we'll have a look at the kind of thing we can do with that a little bit later. There is one more option. If we go to revert the project again, so I'm going to revert to saved. Okay, just take a minute to update those changes and open up the Cineware effect again. What you can do is switch on Cinema 4D Multi-Pass and say just add image layers, and it will add all of the Multi-Pass Layers that it presumes you will need to create this image.
And if we a look down here now, you'll notice that it's added all sorts of passes. We've got atmosphere, atmosphere multiply, refraction, reflection, ambient seclusion, global illumination, caustics, ambient, shadow, specular, diffuse. Now I generally don't want to use that many layers. It starts to really slow down after effects. If you use more than you need. So I tend to just use a selection that I know I'm going to need. But that's two or three options of how to use multipass, either by setting individual passes, working with defined multipasses Or just working with the default set that the Cineware effect provides you with.
