    Hi Trad. Great looking addon. I’d love to buy it and use for animations that have the view switching between multiple cameras. Is there a simple way to do that?

    • @Tradigital
      @Tradigital  14 часов назад

      Actually now there is, but it will be a bit of a challenge in the geometry nodes tree, this is all going to be automated in my next update but basically you can replace the camera input in the node tree with “active camera node”. That will pull the location of your active camera instead of the selected one!

    I really love this modifier, but I have a problem with the resolution. Even just a simple cube with a large diameter (e.g. 10m) will results in a line art mesh with millions of vertices. Could you add an option to adapt the resolution of the generated line-art? Or am I missing something?

    Nice approach. Did you test it in a real production environment? We used grease pencil for a tv show. We had between 1.000 and 30.000 Objects in one scene. Grease pencil was able to handle it, but it was a real pain, because of speed and memory limits. But we made it in combination by using cache rendering. I've also tested a small geometry nodes solution like yours, but not that complex, to be honest. It was too slow at some point and not usable for serious projects. I really like your work, but it's really not that easy to create solutions for real professional projects instead of small presentations. But this problem have a lot of Blender addons. Keep on your great work, Alan! 👍

      @ChristophWerner 10 месяцев назад +2

      Small addition: The most people forget to implement distance based lineart. In production we need a limit. Far objects don't need lineart at all and objects very close to a camera have to keep a thin line width, beginning at a custom position. So if an object starts to approach at the distance of 2 meters to the cam, the line have to stay equally thin. Just a hint...

    Hello, I just bought this today. I was wondering if you could show us how you enable the lineart after you have animated something (character or objects ) with this node. After animating I would love to use this node, however its lagging a lot after I have applied the node as my last step in a non animated scene.

    • @Tradigital
      @Tradigital  9 дней назад

      Hey! Even though this is a “Live” effect, it is not realtime. So you won’t ever want to have it enabled when working on your animation. Think of this as an effect that you will enable right before you render out your animation. Posing and animating should all be done before the line art is enabled. I think that answers your question, but if you have more feel free to ask!

    As a 2d artist that use blender as an assist, i NEED the lines to be rendered in a transparent background without any geometry, is there any timeline for when it will be added or any workaround you could point me at?

      @@Tradigital Yes. I see a lot of line art tutorials and addons, but most of the times they are in solid color and doesn’t have any shading. So I was curious if I can apply different shaders that react to lighting in your line art modifier. It would be cool if line art color will dynamically change based on a lighting position with a gradient. So in the shadow side will be one color and in the light a different one. But I will definitely try your modifier now!

    When you are using this modifier, does it lag as much as the original object line art in blender

    • @Tradigital
      @Tradigital  8 месяцев назад

      It is pretty much the same as the Grease Pencil modifier. It has more options that can make it slower, but if you just stick with the default contour and crease like the Grease Pencil line art, then it will be pretty much identical. Both shouldn’t really be used with your scene while you do animation or composition changes. This is something you will enable at the end and render out with your scene. Almost like a compositing effect.

  • @dornardo

    Is there a way to have the stroke thickness in screen space so that the thickness is always a certain pixel size? I did make a driver that makes the thickness increase or decrease depending on field of view, but couldnt make it change depending on the distance since i couldnt understand how z depth overhaul works and it's origin point

    • @Tradigital
      @Tradigital  10 месяцев назад

      So yes, there is a couple of ways. The easiest way is to multiply the thickness by distance that it is from the camera. If you use the location of the camera and the position of each point, you can subtract it to find the distance and then multiply that.
      Next is a bit more complicated but gives better results. Basically your goal would be to flatten the strokes in screen space in front of the camera before adding the thickness. There are some complicated ways of doing this with vector rotation and set position, but if you want an easy way, you can use the canvas plane method I used in my painterly filter and then raycast the line art onto that plane.
      I know this is a bit complicated but I do want to assure you that it is possible. I also have this feature in my advanced version of the line art modifier if that is easier for you. Let me know if you have anymore questions!

    • @Tradigital
      @Tradigital  10 месяцев назад +2

      There are a few settings that I do not always recommend on lower end systems, especially on very heavy models like this one. Cast shadow, intersection, and shadow infill are all generated completely through geometry nodes instead of just coming from the model like the other forms of line art in this case.
      I would recommend if your system is struggling to compute them, to just find the average settings you would like and then disable them until you do your final render. They can be quite heavy, especially on lower end systems.
      Also, enabling the timing in the geometry nodes panel will show you the performance on each setting when you enable or disable it, this could also be useful for finding a setting that works for you.

      @@Reaching1 ok I think I’m starting to see your issue more clearly. Keep in mind that no line art method is going to work in realtime with animation. Even on the small scenes, this line art tool (especially with the new simulation zone updates) and grease pencil’s line art can take around 50-150ms to compute on my i7-11700K. That is pretty good, especially for rendering, but that doesn’t mean that it is realtime where you can watch the animation play. Effects like these are what you disable while setting up your animation and then re-enable before you press render. Even the invert hull method of line art can drastically slow your animations since it is doubling whatever poly count you have. I’d love to see these methods work in realtime, but none of them are going to give you that even on a decent PC.

    Why is so heavy? I'm doing something wrong?

    • @Tradigital
      @Tradigital  7 месяцев назад

      It is most likely due to some of the settings you have enabled. Many of the lines that are generated come from the model itself, like the contour and crease lines. Then there are other lines that require very heavy computation to generate where they will appear because they do not already exist. That could be things like cast shadow, shadow infill, and mesh intersection. To get these to work, I have to many times give more information to your model so that I can extract where the lines will be. If you are having performance issues, I would recommend turning those off until you are in the rendering stage. I would also not recommend using the line art at all when working on animations. Disabling it in the outliner should give you your performance back.
