1.2.0

New Additions

• Added an Accumulate node that combines a range of timeline frames into a single image, supporting grayscale, color, UV and normal textures
• Added a custom curve mode and weighted scale for the accumulation in the Sheet Encode node; this also fixes a scaling issue in the sample weight, and old presets keep their behavior
• Added a histogram overlay to the 2D viewport (toolbar button or Ctrl+Shift+5); shows the 256-level distribution of grayscale images or of the red, green, blue and alpha channels of color images
• Added an Equalize node that equalizes the histogram of an image so every level is equally represented, with Luminance and Per Channel modes for color images and a Strength control
• Renderer gained three tonemapping operators: GT7 (Gran Turismo 7), AgX and Khronos PBR Neutral
• Color Interpolate and Color Gradient nodes gained OKLCh, Spectral, HSV Smooth, CIELAB, RYB and Beer-Lambert interpolation modes
• Added a Geo Subdivide node that applies up to 6 levels of Catmull-Clark subdivision to geometry; hard edges are kept sharp (creased)
• Grid node gained a Tileable option; the hexagonal grid now tiles seamlessly at any width, and its islands output merges hexagons split across edges into single islands
• Added a Snap to angle option to the rotation randomization of the Grayscale Fractal, Color Fractal, Grayscale Polar Scatter, Islands to Gradient and Islands to UV nodes (snaps the random rotation to the nearest multiple of the given angle, 0 disables it); the Grayscale Tiler Snap rotation dropdown gained a matching Custom option
• Added a Viewport Dithering preference that reduces 8-bit color banding in the 2D and 3D viewports (on by default)
• Added an Image to Material node that extracts albedo (de-lit), height (with optional edge-preserving denoise) and roughness maps from a photo; supports tiling so the maps stay seamless for a seamless input (heuristic, frequency-based; best for flat-lit material photos)
• UV Noise node gained an Add Z axis option with Z position and Z layers for animatable noise that loops seamlessly (Z position 0% and 100% match)
• Tile node techniques gained a Blend mode option: Linear, OKLab (avoids muddy seams), or Soft Blend (keeps detail and contrast — per-frequency on Mirror/Scale, variance-preserving on Voronoi)
• Added snap-to-frames support to the timeline
• Geo Shapes:
  • Cone gained a Top radius option
  • Torus now uses dedicated Minor radius parameters; old presets are migrated automatically
  • Added a Pivot at bottom option
  • Added a Geodesic Sphere primitive (subdivided icosahedron)
• Added a Geo Complex Shapes node:
  • Supershape — organic/star-like forms from the Gielis superformula
  • Torus Knot — a tube swept along a (P, Q) knot curve
  • Helix — a tube swept along a coil
• Added a Geo Honeycomb Shapes node:
  • Spline-sweep mode: connect control points and the node wraps a honeycomb strip along the spline (uses the points' orientation to roll the tube when present, otherwise a rotation-minimizing frame)
  • Sphere
  • Plane (with Bend X and Bend Y options to bend up to a torus)
  • Hexagonal patch
  • All of the above with an adjustable gap between cells and a cell height for raising cells into spikes or sinking them into holes, plus an option to bake a per-cell pivot, orientation and id
• Added per-node timings to the node graph (can be enabled from the preferences under Show GPU Timings)
• Added graph frame rate and UI frame rate to stats
• Added interpolation mode selection for all keys at once in the curve menu
• Added a Keep relative center position option to the Auto Crop node, with an adjustable Pivot gizmo

Improvements

• Improved the 3D viewport bloom:
  • Anamorphic radii (for horizontal or vertical streaks)
  • Dirt/dust masks, with support for normal maps
  • A much larger maximum bloom radius
  • Frequency modification (effectively allowing you to change the blur's falloff shape)
  • Firefly/sparkle reduction
  • Up to 2x faster than before on Apple Silicon
• Improved load balancing performance and stability for graphs that require high amounts of GPU time
• Optimizations:
  • Directional Blur node optimized, output is identical
  • Blur node uses a two-pass filter when its radius isn't modulated, output is close to the previous version
  • Grayscale Filter blur (Gaussian/Sharpen/High-pass) uses a faster mip-bounded separable Gaussian, output is close to the previous version
  • Glow node uses a separable multi-scale bloom, output is close to the previous version

Changes

• Renamed the Auto Crop node's Uniform cropping option to Keep aspect ratio

Fixes

• Fixed Color Gradient alpha being gamma-corrected in the RGB and OKLab modes; alpha now interpolates linearly
• Fixed 'autolink' for dangling reroute nodes
• Fixed the Import Model node forgetting which mesh layer was selected when reloading a project
• Fixed the color picker not working on macOS
• Fixed Auto Crop node cropping for non-square sizes and mismatched resolutions

New Node: Accumulate

The feature has been released and is available in public builds.

1

Added an Accumulate node that combines a range of timeline frames into a single image, supporting grayscale, color, UV and normal textures. We still have the accumulate function inside of the sheet encode node, but felt that it was better to copy the functionality to its own dedicated node. This also allows us to support many input types.

Dropdown & Node Menu Previews

Nicholas Seavert

Posted on April 28, 2026

Released

The feature has been released and is available in public builds.

3

I had a big issue where I was always using the arrow keys to see previews of how each blending mode worked for any given situation. I figured the way it should be done is to actually have a live preview based on your exact situation for ALL dropdowns. Once we implemented this, we decided to also add previews to the node menu as well, so when you drag off of a pin to add a new node, it'll give you a preview of all nodes.

Parameter Comparison Preview Matrix

Nicholas Seavert

Posted on April 28, 2026

Released

The feature has been released and is available in public builds.

2

Some nodes have a lot of information and it's hard to get an idea for how flexible the node is, or what all of your options are for the various parameters. You can now use CTRL + SHIFT + M on a node to open the preview matrix and compare two parameters. In the future we may add a way to compare against 3 parameters. Clicking any preview will select the correct settings for that to overwrite what you currently have in the node.

This is super useful for comparing noise types along with octave blending modes, directional blur modes, blend modes, and more.

Nicholas Seavert

Posted on April 28, 2026

Released

2

We added the ability to edit each point for a spline in a data table view in the node details panel. This isn't a perfect solution to fixing spline editing, but at least you can zero out an axis to ensure that a spline is on the axis' you want.

1

New displacement spaces added where you may want noise to have effect in various direction types such as:

• Along Normal
• In 3D World Space
• In 3D Local Space
• On Tangent Plane

For now this does not apply to the Geo Displace Node and is only available through Geo Noise.

Independent Node Resolutions

Nicholas Seavert

Posted on December 1, 2025

Released

The feature has been released and is available in public builds.

2

2D nodes can now have independent resolutions on a per node basis. We have 3 inheritence or setting options:

Size Source

• From Parent: Inherits scaling based on the parent node connected to it
• From Graph: Inherits scaling based on the global graph settings in the top hot bar.
• Absolute: Allows you to set a direct resolution without using multipliers i.e 256x1024

With this also comes direct, separate, relative width and relative height settings.

Because the node settings for the "texture tab" are now rather large, when clicking a node we will jump directly to node specific content and you would need to scroll up to edit the texture tab info directly. This is a QOL change.

Import Streaming Image Sequences

Released

The feature has been released and is available in public builds.

4

Using the import texture node, you can now stream in image sequences. If your file is named smoke_01, smoke_02 etc you would need to stream it with a file path edit like .../Smoke_##.png with two hashtags where each individual tag equals one number position.

Released

The feature has been released and is available in public builds.

1

Breaking Changes

• All combine nodes have been renamed and modified to expose parameters in a clearer way:
  • Geo Combine Transform -> Geo XForm
  • Geo Combine Scale -> Geo Scale Points
  • Geo Combine Color -> Geo Color

Fixes That Break Stuff

• Fixed orientation inconsistencies with mesh pivots. Some of your projects may be disconnected or scaled in a different way.

Node: Geo Mask

Nicholas Seavert

Posted on December 1, 2025

Released

The feature has been released and is available in public builds.

5

Added Geometry Masking capabilities. Geo Masks are defined using the Geo Mask node and can be applied to all geometry node types. These masks are useful when you want to apply geometry operations to specific mesh locations. In the Gif seen above we have an animated mask based on the distance from the animated position of the Geo Mask gizmo.

Optical Flow/Motion Vector Generation

Nicholas Seavert

Posted on October 8, 2025

Released

The feature has been released and is available in public builds.

12

Optical flow as a method is more accurate than something like EmberGen's motion vector pass. IlluGen will allow you to create motion vectors for any animated input.

Optical Flow Node: Generates the optical flow map based on a number of settings within the node. We support standard motion vector outputs, flow pin, and dual flow outputs, which is a combination of the flow and inverse flow pins. Blend Flow Node: Allows for playback of a flow map of any sort (UV input, Optical Flow, Motion Vector).

With the optical flow feature comes 3 new projects detailing how and when to use specific settings for creating optical flow maps and the settings required. Project optical_flow_3 details how to use the dual flow optical flow method. This method for Dual Flow was suggested to us by "Crestycomb" on discord and we've added this experimental functionality based on those suggestions.

[Edge Detect] - New Edge Detection Methods

Nicholas Seavert

Posted on December 1, 2025

Released

The feature has been released and is available in public builds.

2

Techniques Available Now

• Sobel
• Scharr
• Central Difference
• Corner Difference
• Sharp Voronoi Edge

Sharp Voronoi Edge is particularly useful because it ensures that all edges/lines are the same color when the edge may have not been precise enough with other methods. Sharp Voronoi Edge allows you to skip using a threshold node to try and boost the color of some lines in the case where you may be making cracks in the ground etc.

• Preview individual color channels, and full color with alpha within our 2D viewport.
• Conveniently check for texture tiling with our tiling texture preview
• Switch between bilinear and point filtering as needed
• Preview normal maps, UV warp coordinates (these are used to warp textures), 2D images, grayscale, color, alpha, flowmaps, flipbooks, 3D meshes, 3D mesh points, vertices, UV's, faces, triangles, quads and a ton more.
• Alpha is not a separate concept in IlluGen like other some tools. Anything can be packed as an alpha channel and can be authored like any other RGB or HSV color channel.
• Brand new node search system when dragging off of a pin: Allows you to easily type the name of a node or node preset.
• Smart and context appropriate node suggestions based on your most commonly used nodes in a given situation.
• Reroute pins: Drag off of any active connection to create a reroute node. This is also the proper way to move a bundle of connections to another pin.

• Curve profile and color gradient presets can be stored in custom folders and be shared amongst teams.
• Any node can become a preset by clicking the dropdown at the top right of the node info window. This is useful in a case where you may have a very cool custom noise texture that you've generated and would like to easily reuse it as a starting point in the future. Once named, you could search for this preset and spawn it right within the node context window (right click).
• Basic PBR rendering support
• Standard shading model support for VFX asset types: Alpha, Opaque, multiply, translucent.
