TOTAL DURATION: 1h 20m 43s

In Copernicus, you can set up slap comps at the Solaris stage level. Learn how to create AOVs that generate useful data to use in these slap comps. Once you learn the basics of setting up a slap comp, you will take a deeper dive into a painterly post-processing effect. After that you will learn how to a render with a background still image, including how to match colors and values. Finally, you will learn how to work with video image sequences as background plates for adding VFX elements.

PROJECT FILES | PART 4
1 | Set up a Slap Comp [9:32]
Learn the basics of using Slap Comps in conjunction with Karma viewport rendering at the Stage level. Learn how to add AOVs to a render, and simplify lighting in COPS. This sets you up for part two, which will teach you how to create a painterly post-processing effect.
2 | Create a Painterly Post-Processing Effect [20:58]
Learn how to create post-processing effects which can be applied through a slap comp. To begin with, you will write a triplanar projection wrangle, project brushstrokes onto a scene, distort a render with a projected texture, and finally use a variety of techniques for making a render look painterly before writing your slap comps directly to disk.
3 | Still Image Compositing [21:36]
Learn how to composite VFX elements with background plates. Bring in an image to be viewed through your camera view then align geometry to the plate and add reflections and shadows using the Background Plate LOP. Learn how you can perform various color corrections to your rendered elements to have them fit into your background more accurately.
4 | Video Compositing [28:37]
Learn how to integrate various VFX elements into a video background. This will reiterate much of the lessons learned in the last section, but will add in how to work with camera tracks and object tracks, as well as how to work with render vars in more meaningful ways to get more specific outcomes from your AOVS.

    Hello, on the second part of the video, is there a way to "fix"/ "lock" the painterly effect? I followed your tutorial for 1 of the project im working on but when the camera moves or object moved/rotate, the edge of the painterly effects moves also.

      Please, can you go more in-depth about the project map? Thanks

        Hope next update bring camera tracker, then Houdini will dominate industry. No need to roundtripping multiple softwares.

          Hi Moeen! you are great with your tutorials!

          Hey, i have a problem... i did all that you said, but when i press the Control Slap Comp Settings button houdini crashes without warning

          Do you know what can be the problem?

            Hey! Firstly, thank you!
            I also had that issue and I struggled to figure out the cause of it. It's important to remember that Copernicus is still in it's early stages as of this tutorial. The one thing that seemed to fix it for me, was making sure of the following:
            1. I had a karma render node
            2. I had a camera in my scene
            3. The karma node references the camera
            4. The karma node has the same dimensions as the camera
            5. The viewport is being viewed through the camera view

            Let me know if that works. I know it's a bit odd, but I assume it will be fixed soon. We tried to submit it as a bug on my side, but were unable to reliably reproduce it. If you can find a way to reproduce it, then please put it through to the SideFX team as a bug.

            I hope this helps!

            Hi Moeen! Thak you for the response

            Unfortunatly this doesnt work for me. I will keep trying but a follow all the tutorial the same as you.

            Something odd its that when a by pass thebackground image, sometimes it didnt crash when i activate the slap comp...

            If i can solve it i will write again!

            Ty!

              Hiya, thanks for this wonderful tutorial! Background plate glossy reflections aren't working for me, maybe a bug, but I've followed the setup 3 times. I tick the box, lower roughness but no change :( Karma is using the correct camera and XPU, tried CPU too but no luck.

                rebuilt again and it worked ¯\_(ツ)_/¯ :D
