What's new in Simplygon 10.4

We are proud to present our next major release. Simplygon 10.4 comes with improvements to the quad reducer, small parts remover and tessellated attributes. It also adds support for Unreal Engine 5.5, Maya 2025 and Blender 4.2.

Unreal Engine 5 plugin update

We are pleased to introduce a new feature in the Unreal Engine 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. For more information see our Python and Blueprint examples.

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

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.

Updated small part remover

The Small part remover is a tool for removing small non-connected parts of a model, for example screws. In Simplygon 10.4 it can now be used as a pre-process step in the reduction pipeline making it easier to use. We have also improved its core functionality. It can now be configured with 3 different targets:

  • Physical size
  • On screen size
  • Percentage of scene diameter

In this example we have used it to remove nails from this furniture in the Blender integration.

Attribute Tessellation improvements

Attribute Tessellation allows storing geometry attributes at a higher frequency than the geometry frequency. This is useful when optimizing very dense geometry as it allows you to work on a lower resolution base mesh. In 10.4 we have introduces some new features.

  • 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.

Compatibility with Maya 2025 and Blender 4.2 LTS

We’re keeping up with the latest software releases. Simplygon 10.4 now supports Maya 2025 and Blender 4.2 LTS, allowing you to seamlessly integrate our software with these updated tools.
