SDK 42

---

New Engine features:

• Introduced node-based API scripting.
• Added support for an unlimited number of mesh morph targets.
• Correct deformed morph geometries tracing.
• Fixed correct normal calculations for non-uniformly scaled objects when using the non-uniform material option.

Tools changes:

• MeshAnimation Explorer extension for animation importing and retargeting has been added.
• SceneScriptFlow Explorer extension, which enables ScriptFlow functionality, has been added.
• ScenePrefab extension with Scattering and all Physics plugins has been added to the Explorer.
• Fragment and Compute app templates have been added to the project tool.

Sample changes:

• MaterialFlow iridescent and marble material samples.
• Object mesh morph sample.
• Many new ScriptFlow samples have been added.

Plugin changes:

• ScriptFlow plugin now offers node-based Tellusim API scripting.
• More socket shapes have been added to ControlFlow.
• ControlFlow type masks now support up to 384 types.
• ControlElement has a new color multiplier parameter.
• Many new nodes have been added to the MaterialFlow plugin.
• Physics plugins support dynamic gravity changes.
• Physics plugins automatically handle body/shape/joint removals.
• Reflection plugin provides information about enums and callbacks.
• ARLink plugin (client to the Tellusim ARLink app) enables real-time facial animation.

API changes:

• New MeshAttribute::TypeIndex attribute type acts as an index to the optimized (source) position attribute. Morph target attributes can be stored in a compact form and accessed via this index.
• Control of the ControlSplit size is now managed within the ControlRoot interface.
• Pressed callback has been added for ControlSlider.
• ObjectMesh::FlagSkeleton transforms the parent NodeObject into the source skeleton for all child nodes (e.g., different clothes on a character).
• ObjectAnimation::setEmbedded()|isEmbedded() flag controls animation embedding within the scene.
• ControlTree now returns the currently focused item for tooltips.
• Expressions now accept non-default matrix names.
• Trigonometric operations have been added for Vector<> types.
• Script scene classes can now store source code inside scene files.
• Object::createLocal()|GlobalTransforms() methods have been added for simple hierarchical node operations.
• A dedicated morph target buffer has been added to ObjectMesh.
• geometry/TellusimLine.h provides line-related math utilities.
• math/TellusimNoise.h provides Perlin and fractal noise samplers.

Internal Clay features:

• Internal FBX loader now supports blend shapes.
• Updated mesh file format effectively compresses blend targets by storing only modified data.
• Default camera’s ZFar clip plane is Maxf32.
• Default point light radius is 100.
• Matrix4x3f type has been added to the Expression parser.

Bug fixes:

• Corrected skinned NodeObject bounding box visualization.
• Script::setParameter(), Material::setUniform(), and Material::setTexture() now no longer cause assertions when an invalid name is provided.
