Simplygon 10 Release Notes ​

Simplygon 10.2.400.0 ​

New features ​

Remeshing processor ​

  • Added settings:

    • RemeshingSettings::PopulateAttributeTesselationDisplacement
      • RemeshingProcessor can now populate floating point vector displacement attribute tesselation fields, as set up by AttributeTessellationSettings, with displacement to the original mesh, without doing any sort of post process cast to texture and baking the texture into the displacement fields.
    • AttributeTessellationSettings::AttributeTessellationDensityMode::OnScreenSize
      • New mode for density in the attributetessellation settings where every tessellated sample gets max edge length ~2 pixels, making the actual triangles take up ~1 pixel on screen.
    • APipelineSettings::ApplyAttributeTesselation
      • Pipelines can now apply the attribute tessellation generated by the processors before export.

  • Major back-end tech rework of RemeshingProcessor.

    • Significantly lower memory consumption at larger OnScreenSizes.
    • Significantly faster processing at larger OnScreenSizes.
    • Known limitation
      • RemeshingMode::INSIDE is currently not fully implemented - Always selects center of mesh as "Inside" point instead of intelligently finding it. Will be fixed in coming updates.

  • AttributeTessellation displacement integration with RemeshingProcessor

    • Generate tessellated displacement directly in the processor which can be exported as GLTF micromesh textures or applied to the mesh to create a densely tessellated output mesh.
    • Automatic conversion from floating point displacement to scalar displacement to be able to seamlessly export micromesh. Exporting GLTF with populated displacement fields will also export the micromesh texture by default.

Billboard cloud processor ​

  • Added FoliageSetting: "SeparateFoliageMaterials" which lets the user specify the names of the materials that should be processed as foliage and replaced by impostors.

NormalCaster ​

  • Added setting: "Flip Backfacing Mode". If FlipBackfacingNormals setting is checked, this new setting decides which source normal we should compare the destination normal with when deciding if the normal is back-facing or not. Changing this from the default "Pixel Normal" to the new mode "Face Normal" can be beneficial for two-sided assets like leaves that can get weirdly flipped pixel normals with the default setting. Mostly beneficial when using the Flipbook processor.

FbxExporter ​

  • Added setting: "ImportFilePath". Path to the imported FBX file used for processing. If set the contents of the file are merged with the processed scene and exported.
  • Added setting: "FlattenCascadedScene". If enabled the cascaded scenes are flattened in depth first order. Name clashes are removed by prefixing with _LOD[Index]. Where index is index of the scene after flattening.

SceneExporterPipelineSetting ​

  • Added setting: "ImportFilePath". Path to the imported FBX file used for processing. If set the contents of the file are merged with the processed scene and exported.(Only valid for FBX files)
  • Added setting: "FlattenCascadedScene". "If enabled the cascaded scenes are flattened in depth first order. Name clashes are removed by prefixing with _LOD[Index]. Where index is index of the scene after flattening.(Only valid for FBX files)

PipelineSetting ​

  • Added setting: "MergeResultWithImportedFileOnExport". If enabled import file information is passed to the scene exporter for merging the contents of the import file into the resulting exported file. (Only used by FBXExporter)
  • Added setting: "FlattenCascadedScene". If enabled the cascaded scenes are flattened in depth first order. Name clashes are removed by prefixing with _LOD[Index]. Where index is index of the scene after flattening. (Only valid for FBX files)

Unreal Engine ​

  • Added support for Unreal Engine 5.2.
