Added support to add metadata to all static mesh actors, not just the initial shape nodes.Fixed a bug in the MultiPatch reader where material properties other than color and texture were likely to be ignored.Increased the written I3S version to 1.8.Added support for the fullExtent scene object attribute.Fixed handling of transparent materials in intermediate nodes.

Fixed a crash when trying to read files with unsupported types 'Spline' and 'Region'.Improved the heuristic to find textures referenced in a moved DWG.Add support for reading vertex normals.Fixed a bug where transformations on geometry nodes where not considered.Do not restrict reading of layered textures to eAdditive.Do not abort decoding if a texture cannot be read.Fixed support for reading FBX assets from memory.Added support for FBX opacity textures.Added support for reading embedded textures in (binary) FBX files.Assets with transparent textures imported from MultiPatches will not write unusual.cgamat) with ids .CGAMatEncoder and .CGAMatDecoder. Added encoder and decoder for CGA material files (.ifc) with id .IFCEncoder and .IFCDecoder. Added a new encoder and decoder for 'Industry Foundation Classes' (.split, trim, insertAlongUV operations: Fixed a rare crash when face materials are present.convexify, setback operations: Fixed a bug which led to wrong uv coordinates and normals in some self-touching and self-intersecting polygon situations.This happened on non-planar shapes with a scope rotation applied. envelope operation: Fixed wrong resulting scope translation.scatter operation: The group name of scattered points is set to builtin:point.splitArea operation: Asset groups and asset face materials are now kept.envelope operation: Asset groups are now kept.String concatenation operator: Strings can now be concatenated with arrays.Added a new convenience function prtx::Material::getShaderTextureArrayKeyAndIndexFromCGAMapName() to find the shader key and array index for a given CGA map attribute.Updated the list of shader keys in the API documentation of prtx::Shader and prtx::Material.Fixed resized texure array when using prtx::MaterialBuilder::setTextureArrayItem(L'diffuseMap', 0).Extended the list of managed pointer types in prtx/PRTUtils.h.Added a new utility function prtx::MaterialUtils::getMaterialAsCGAStrings to get the string representation of a prtx::Material.Prevent the creation of small holes when merging vertices in prtx::EncodePreparator.Fixed wrong syntax in the output of prt::ResolveMap::toXML.Improved robustness when closing files.Added support for creating intermediate directories specified in the open function.Enhanced the prt::FileOutputCallbacks class.CityEngine SDK is used in CityEngine 20.This section lists changes compared to CityEngine SDK.
