Awesome. A lot of people were looking for this one - thanks Rohan!

@MIXTraining Ай бұрын

Very nice and simple to follow, great job, thank you

This is so powerful... exactly what I needed. Sidefx rocks!

Thnk you Rohan very much! Please make tutorial how to apply toon fx to complex scene with materials?

@HristoVelev Ай бұрын

Very nice :) Would be cool to send the outlines to sop, add some detailing there, and get them back to cop :)

@rohandalvi Ай бұрын

You can do that, but you have to do it at sop level.

@HristoVelev Ай бұрын

@@rohandalvi trace sop should be able to turn the image to lines?

@rohandalvi Ай бұрын

@@HristoVelev yeah, i tried that. It works nicely but it creates a polygon. I wanted to create curves so i can render it with width. The issue is that it creates two curves Because it generates an outline.

Thanks for the tutorial, this is great, also, remember you can turn off the preview of the cop nodes to save space and performance.

Great and simple description! As always! Thanks! Copernicus seems to hide a lots of opportunities

Wow very cool, never used COPs in this way - thanks for making this! One problem I have is not getting live updates - I have to toggle the "Slap Comp" button on the viewport on and off to get an update for every change. Anyone know why that could be?

@Fakepilot Ай бұрын

That's incredibly easy, useful and cool. 😀

@atefezare5623 Ай бұрын

excellent tutorial! thank you! looking forward to more cops tutorials.

@bentway23 Ай бұрын

Fantastic! I would love to see a follow-up on how to render, though--those help docs get a bit esoteric and I have yet to be able to get it to work. A render image rop within the copnet just spits out lots of copies of whatever frame is in the viewport, and rendering through the usual render rop--even with slap comp enabled in Husk--doesn't seem to pick up any of the copnet stuff.

I have a training series on my website for building toon shaders and outlines in SOPs. You can take a look at that. It might be useful.

@denmla79fx53 Ай бұрын

great tutorial! I tried to render via husk like you showed but it just renders beauty pass without the copnet. Any ideas why?

@rohandalvi 28 күн бұрын

I haven't tried it yet. I'll try it and let you know

@Puhvaika 18 күн бұрын

I'm having the same problem. It doesn't seem to render the slap comp.

@Puhvaika 18 күн бұрын

I was able to render out from ROP Image Copernicus node straight from the COP network, but it doesn't use the time information so every frame is the same depending on what frame you are on the timeline. For single images it could be used, but for animation it does not seem to be the solution.

Is it possible to get a render WITHOUT using karma?

@rohandalvi 5 күн бұрын

It is a post process, so you need a base render from somewhere doesn’t have to be karma, use any render engine. You could do a screenshot of the viewport and work on that but you’ll need something.

Hello, when I export the geometry it appears in gray and not with the colors and contours that I have in the viewport.

@rohandalvi 10 күн бұрын

It’s a post effect. You’ll need to render tha base render and then Load it into cops using a file node and apply the effect to that . And then render that out using a rop output node.

Would that be also possible with Redshift ? Great tutorial thanks :)

@rohandalvi Ай бұрын

As long as redshift gives you AOVs and is capable of using a slap comp, the method will remain the same. I can't make a tutorial on redshift because i don't have redshift.

If you use a karma sky the alpha trick doesn't work.

@rohandalvi Ай бұрын

Check if there's an option to not render the sky in the light settings.

@MIXTraining Ай бұрын

yes, you need to turn off the light showing in the viewport or you could use the z depth to get the alpha of the object since they are far apart

@slick3d392 Ай бұрын

@@MIXTraining Yes, I used the depth information, but wat I want is exactly to have the sky rendering. Anyway, I'm looking for a way to do the cel shading without the post effect, directly in the copernicus nodes.
