Defold release 1.13.1

Defold 1.13.1 is a substantial engine and tooling update aimed at both rendering workflows and day-to-day iteration. The biggest headline is first-class Light components for ambient, directional, point, and spot lights, with editor-side creation, previewing, and automatic shader binding through a LightBuffer. That makes lighting authoring much more approachable in Defold while still leaving the rendering model flexible for custom pipelines.

The release also extends the morph-target work introduced in 1.13.0 by allowing instanced models to carry per-instance morph weights. That matters for teams pushing lots of animated or deformed copies of the same asset, such as crowds, vegetation, or stylized effects, because it keeps the GPU instancing path intact while varying expression or shape.

On the workflow side, Defold is clearly leaning harder into external tooling and automation. Editor scripts can now build richer non-modal UIs, use tabs, inspect images, query the active editor view, and fetch libraries programmatically. The editor HTTP API adds /ref for live API lookup and /preview for rendering scenes to PNG, while installations.json gives third-party tools a reliable way to find installed editors. Those pieces together make Defold easier to integrate with IDEs, pipelines, validation tools, and AI-assisted workflows.

There are also practical quality-of-life improvements: SDL controller mappings are enabled by default, warm builds are up to 19% faster in large projects, borderless fullscreen is now the default on desktop, HTML5 audio handling is more robust, and an...
