This page contains information on all the ArtEngine releases of 2022, including new features and fixes.

The versions are listed in order of release, from most recent to last.

Officially supported Nvidia Drivers

Versions 461.72 or later.

ArtEngine version 2022.3.1

Release date: March 8th, 2022

New Features and Improvements

HDRP 3D Viewer - Load custom meshes

  • You are now able to load your own meshes into the Unity Window from the Node Graph by right clicking in the Node Graph and choosing ‘View in HDRP Viewer’. You can also load your own materials onto these meshes.

Clone Stamping - live wrapping view

  • You are now able to see a live update of your textures tiles in the 2D viewer, so you can see if your seams will tile correctly as you are making changes. The wrap edges checkbox for clone stamp should be ticked to enable this view.

CLI - Better control of parameter settings 

  • You can now edit parameters of nodes without changing the xml directly. The CLI node parameters can be named by adding an attribute to the XML Model sub-elements in the graph file, and CLI node parameters can be specified with CLI parameters.

Chrome Ball - Workflow Change and CLI compatibility

  • We changed Chrome Ball to use input pins instead of a folder path. This means that within the ArtEngine UI you can bring in your scanned chrome ball images (up to 16) and then right click to add them directly to the Chrome Ball node. Then you can either bring in your chrome ball mask image or use mask paint to draw it directly. The chrome ball mask input is required to execute the node. 

  • If you still want to use a folder path process within ArtEngine UI, you can use the batch input node, split materials, and assign individual images to the chrome ball inputs. Make sure the number and name are always the same, paying special attention to the Chrome Ball Mask input.

  • Chrome Ball node can now also be used from the CLI, which was the main reason for this change. 

Resolved Issues

  • We have added a more detailed error message when using Style Transfer (Beta). As a reminder, Style Transfer can only accept a maximum of 1k inputs.

  • Fixed issues with the HDRP Lit Specular Color material causing the materials in Unity to look overblown.

  • Fixed an issue where the Templates files were not loading into ArtEngine correctly.

Known Issues

  • When executing a batching process, please execute the batch input node for best results. Pressing execute all causes batching to skip some input folders.

  • If one input folder has more maps than another Batching will create extra black maps in the output folders to make up the difference in numbers, 

  • Mutation Revision doesn't work on resolutions that are not a power of two (e.g. 1K, 2K, 4K, etc)

  • Seam Removal, Mutation, Mutation (Structure): using an Ignore mask with hard edges may sometimes cause artifacts in the output of these nodes. There is a known workaround for this problem, which is to blur (or feather) the mask edges. You can do so in one of the following ways:

    • When creating the mask using a Mask Paint node, you can adjust the hardness property of your brush at the time of painting to ensure mask edges are feathered.

    • When working with an existing mask, you can pass it through a Blur node before connecting it to the Ignore port of Smart Mutation nodes.

 2022.1.1

ArtEngine version 2022.1.1

Release date: February 17th, 2022

New Features and Improvements

  • Unity Window

Camera Controls: Camera project can be now changed between Perspective and Orthographic. You can now use the mouse wheel to zoom in and zoom out. In addition, the FOV can be adjusted between 15 and 150 from Perspective projection.

Lightbox Controls: You can now choose from a list of preloaded HDRI using the Skybox option under the Lightbox Control settings in the Unity Window.

Light: The light can be moved around the object using Shift+RMB+Mouse Pan. The light can also be turned on/off using the toggle.

  • UI Refresh - Icons

The interactive icons throughout the user interface have been tastefully upgraded to make it look clearer and more user friendly.

Resolved Issues

  • Clone Stamp

    • Undo sometimes cleans all of the painted strokes, if undone quickly.

    • Sometimes cannot paint strokes after imbuing.

  • Fixed an issue where Mutation nodes failed to handle duplicate maps.

  • Fixed App crash when loading a 3D model to the node graph.

  • Fixed App crash when trying to move a folder in the asset library by dragging.

  • Fixed an issue where the Ambient Occlusion node failed to produce preview when connected in a batching workflow.

  • Fixed Height Generation node failure after a few executions.

  • Output map types were not updated when input map types were changed in Mutation Revision.

  • Fixed issues with Ignore Mask on Height Map for Seam Removal and Content-Aware Fill.

Known Issues

  • Seam Removal, Mutation, Mutation (Structure): using an Ignore mask with hard edges may sometimes cause artifacts in the output of these nodes. There is a known workaround for this problem, which is to blur (or feather) the mask edges. You can do so in one of the following ways:

  • When creating the mask using a Mask Paint node, you can adjust the hardness property of your brush at the time of painting to ensure mask edges are feathered.

  • When working with an existing mask, you can pass it through a Blur node before connecting it to the Ignore port of Smart Mutation nodes.

  • Nodes that are not recommended for Batching: Color to Mask, Color Muse, Mask Paint, Color Transfer, and in general nodes that are more specific to the individual bitmaps coming through.

  • There is an issue with Batching creating extra black maps for output folders to make up the difference in numbers, if one input folder has more maps than another. 

  • Please note that GPU driver requirements for ArtEngine have been recently updated. ArtEngine now supports NVIDIA GPU driver versions 461.72 or later. The newer drivers greatly improve execution speeds of the Up-Res and JPEG Artifact Removal nodes, as well as neural pattern matching in the Mutation (Structure) node. If you have an older version of the driver, you will be prompted to update it the first time you launch ArtEngine.

 2021.16.1

ArtEngine version 2021.16.1

Release date: January 19th, 2022

New Features and Improvements

  • UI Refresh to our Tooltips and Node Graph

A refresh to our system’s helpful tooltips and node graph to improve your ArtEngine experience.

  • Unity Window

Users can now use HDRI maps to light their Unity Window scene and turn a point light on and off. There are now more camera settings as well. 

  • Improved AO processing time for Baker

We have added a GPU baker to the Baker node, which has faster AO baking than the CPU version. GPU is set as the default, but you can still use the CPU baker if that fits your workflow better.

Resolved Issues

  • Clone Stamp

    • When the stroke is undone, it is no longer visible on any of the maps.

    • Fixed the issue where you could not use mask paint downstream.

    • Fixed the issue where the execution status was lost after the project re-opened.

    • Fixed the issue where you could not preview maps after node execution.

    • Fixed the issue where clicking outside of the texture in 2D Viewport disabled maps in the list.

  • Chrome Ball’s Backwards compatibility has been fixed.

  • Fixed Compose Material’s hard crash when imbuing map from solid colour node.

  • Fixed the issue where ArtEngine crashes with Unity Viewer and 16 bit maps.

  • Fixed an issue where there was no 'My Templates' tab in templates.

  • ArtEngine can now allocate more memory for a large number of images.
