News in Simplygon 10.4 ​

Support for Unreal Engine 5.5 ​

As part of our commitment to keeping Simplygon compatible with the latest Unreal Engine versions, we are pleased to announce that our UE plugin now supports Unreal Engine 5.5.

Blender 4.2 LTS support ​

This long-term support version of Blender brings stability and new features, and our Blender Add-on is now fully compatible with this latest release.

Autodesk Maya 2025 support ​

This update ensures our Maya plugin compatibility with the latest version of Maya, allowing you to seamlessly integrate our tools into your content creation workflow.

Export/Import of Static Mesh Actors via Blueprint/C++/Python ​

We are pleased to introduce a new feature in the UE plugin that expands the possibilities for scriptable access and operations on Static Mesh Actors.

Designed to offer greater flexibility and control in your workflows, this feature complements the capabilities of the existing Stand-In Actor and is particularly beneficial for complex operations that require a high degree of customization to meet your specific content pipeline needs. Among other potential use cases, this feature, in combination with Simplygon's remeshing and aggregation processors, can be used for the merging of multiple scene mesh instances into a single Static Mesh Actor, including material baking.

Small Part Remover ​

With introduction of new Part Remover tool, we are enhancing the reduction process by eliminating small, insignificant parts of a mesh before reduction. This tool is particularly useful for assets composed of loosely connected meshes with many small parts, which often contribute significantly to the poly-count without affecting the overall visuals at a distance.

Improved quad reduction on flat shiny surfaces ​

We are pleased to announce enhancements to our quad reducer. It now delivers improved output quality when handling flat, shiny surfaces, particularly benefiting game assets like cars, ensuring a more polished and accurate result.

Attribute Tessellation improvements ​

• Shading Network Support: We've introduced support for shading networks during displacement injection for attribute tessellation, allowing for more complex and detailed surface representations.
• Vertex Color Casting: Tessellated attributes can now cast vertex color data to tessellated vertex colors, maintaining color consistency across the model.
• Bone Influence Addition: Bone influences are now included in tessellated attributes, improving the deformation and animation of tessellated models.
• Attribute Tessellation Copying: Fixed an issue with attribute tessellation copying when using reduction, ensuring accurate data transfer.

Increased Bone Influences in glTF ​

glTF now supports up to 8 bone influences per vertex, doubling the previous limit of 4 and allowing for more complex animations.
