@AversionReality This will be supported in the compositor in: projects.blender.org/blender/blende…

Malt's method is based on this great article. I'm not yet sure that I can get proper Jump Flood working in the Compositor, but performance is less of a concern in Blender than in real time games. bgolus.medium.com/the-quest-for-…

It is time we had better line art options in Blender. I use the Malt render engine because it is great, especially the line art. But it isn't always viable to use. So I wanted to see if the Compositor can handle Malt style line art now since recent updates let us do more with passes and even AOVs in the viewport. This is only a proof of concept with many issues and missing components, but the answer seems to be yes! Unlike the regular Filter based lines, these use a two step process: detect a line mask, and then expand it. This gives a lot more control. And with AOVs, we can control the parameters with data from the Material or Attributes, like I use in my Malt setups. I am also testing out using the new Convolve node for this. For big kernels it should be more efficient. But for typical thickness, spamming Translate nodes is probably better. If I don't run into problems, I'll see about turning this into an addon. I assume some nice line options are planned for the NPR features that are in development, but I'm not sure how long until those will be ready.

@DanMaslyn No, a bounding box would cover the entire voronoi cell. Here, we are taking about the circle that is inscribed in the voronoi cell. See en.wikipedia.org/wiki/Inscribed…

@OmarEmaraDev So it's basically the bounding box for each cell?

@OmarEmaraDev If you have a moment, can you explain n-sphere in the Voronoi texture? I read what you wrote about it in the documentation but I didn't understand it. I'm trying to make a texture that distributes shapes randomly across the surface.

Blender v4.4 is released! We rewrote the entire CPU compositor, providing significant performance uplift in some cases, better interactivity, and less memory usage. The new architecture should make future development much easier, so stay tuned for the future. #b3d #devfund

@3pointedit @blue_nile_3d @Trinumedia This is not merged yet, use those test builds: builder.blender.org/download/patch…

@OmarEmaraDev @blue_nile_3d @Trinumedia Hmmm, I cant get it to work in the latest daily build?

💻 Don't know about you, but multi-pass realtime compositor for EEVEE Next (Blender 4.3) is about as exciting as it can get! Now.. where's my screenspace refraction to Shader to RGB!? Then I'm jumping ship to this spaceship! projects.blender.org/blender/blende…

@blue_nile_3d @3pointedit @Trinumedia They will also be available, not sure when exactly. Trying to get EEVEE working as a first step.

@OmarEmaraDev @3pointedit @Trinumedia AMAZING!!! Thank you so much for your hard work! Do you have any idea if/when realtime AOVs will be available for cycles?

@Trinumedia @3pointedit Yes. This screenshot was actually from the viewport compositor. There are some tests builds here if you want to give it a try. projects.blender.org/blender/blende…

@OmarEmaraDev @3pointedit Yes! And soon to the realtime viewport compositor?

@3pointedit @Trinumedia EEVEE supports AOV passes, so you can just create a UV AOV pass and access that from the compositor. Just make sure to add 1 to the Z component because that's what the compositor expects.

@Trinumedia Arrrggghhh no UV pass in Eevee :(

The GPU Compositor is now official! 🎉 Blender 4.2 LTS will make use of your GPU to power compositing setups. Available in the Options tab in the Compositor sidebar, and the Performance panel in Render Properties. Congratulations VFX module! projects.blender.org/blender/blende… #b3d

@3D_director The pass itself is not supported unfortunately, so not at the moment.

@3D_director This is probably best handled as a bug report.

@3D_director @dfelinto @erindale_xyz If the node didn't convert automatically, report this as a bug with the file.

@OmarEmaraDev , @dfelinto is there an alternative setup to recreate the musgrave texture back in Blender 4.1? @erindale_xyz have you seen this in 4.1?

Hello #b3d friends. In Blender 4.1, "Musgrave texture" doesn't exist anymore. Is there a solution to bring back that node? I need coherent procedural shoe bumps. Left: 4.1 Right: 4.0

@Trinumedia @Laserschwert_ Actually the banding is due to limited precision. You need to change the precision to Full in the node tree options to avoid it. This option is in 4.1 only, hence why I only enabled the pass in 4.1. This Full thing will happen automatically in the future. devtalk.blender.org/t/real-time-co…

@Laserschwert_ Since the display is RGB 255 when it comes to values, and the Zdepth a float to scene/camera clip depth essentially, when it's normalized to the display, the float steps are clamped to pixel luminance steps, which are a fraction of the full float - thus stepping the values.. ?

BIG NEWS. Blender 4.1 has realtime multipass of the Zdepth - meaning you can now viewport composite with depth in realtime! Exciting time. And.. it happenstance will also be in Bforaritsts 4.0.1.

@bipmatt That makes sense. I will look into it.

@OmarEmaraDev Hey there is it possible you can release this with 3.6 it’s just updating it from python 3.7 to 3.9 I thinks Thanks Matt . You’re plug-in looks amazing

#AnimationNodes v2.2 is finally released! It features Attributes, MIDI, New Falloffs, Spline Curvature, Extensions Support, Shortest Path Trees, Spline Bevel, and many more features! Download: #Download" target="_blank" rel="nofollow noopener">animation-nodes.com/#Download Release Notes: docs.animation-nodes.com/release_notes/…

@andrewpprice It is already in master behind an experimental flag. It will move out of experimental in 3.5 and will be officially part of the 3.5 release. However, MacOS will not be supported and there are a number of limitation as shown in developer.blender.org/T99210.

Anyone know which release we can expect the real-time compositor to be in Blender master? #b3d

@3D_director @ilychris_ @afeso_art @deadtunnelrat Yes. It is available in the daily builds.

@OmarEmaraDev @ilychris_ @afeso_art @deadtunnelrat AWESOME! Thank you for the updates! Also: is it available on today's daily?

@OmarEmaraDev Hello. I am trying the realtime compositor, but I noticed there is no option for EXCLUSION in the MIX node. Is it possible to add it? the formula for EXCLUSION is : f(a,b)=a+b-2ab. youtu.be/F7_kaTP7_W4?t=…

@3D_director @ilychris_ @afeso_art @deadtunnelrat Charlie implemented and committed that last week, so it will be part of the 3.5 release. developer.blender.org/D16543

@ilychris_ @afeso_art @OmarEmaraDev @deadtunnelrat I remember @OmarEmaraDev sent a commit, but I don't recall being approved yet. The code was relatively straight forward, but it needed to be implemented in different editors (and brushes) all around Blender.

@3D_director If you think it is a bug, just open a bug report. If not, just send it in a private message on twitter.

@OmarEmaraDev Sure. How do I send it to you?

Hi @OmarEmaraDev I'm trying Image+Blur(Multiply) using a Mix RGB with image+Blur(Screen). I get the red noise for "eevee bloom Emission materials"[right image]. It looks like a clamping issue, but "clamping" in the blur node does nothing.

@danielpartzsch It will be release as part of 3.5. It should be safe to use in production, taking into account its limitations and compatibility against the existing compositor, which will be documented.

Hey @OmarEmaraDev I was wondering what's the status of the Realtime compositor? I thought it was supposed to be released with Blender 3.4? Is it save to use it in production already for the features that have already been implemented? Thank you!
