EdenSpark Update 0.0.4.6

Dynamic GI, skeletal animation, behaviour trees, MCP server, new mesh optimizer and more! Dive in to learn details!

Skeletal Animation Sample

A new sample project demonstrates how to add skeletal animations to your game using the `SingleAnimationPlayer` component. More advanced samples covering blending and state transitions are planned for future releases. In the meantime, the (https://docs.edenspark.io/index/scene_core.html#sample_animation_and_blend) is available for building custom animation controllers.

Behaviour Tree Module

A `engine.ai.behtree` module provides a behaviour tree framework for building game AI in EdenSpark. Compose trees from built-in leaf, decorator, and composite nodes — or subclass `BehNode` to create your own. The module includes lifecycle hooks, a reaction system for interrupt-driven priority changes, and debugging helpers to visualize tree state at runtime (https://docs.edenspark.io/index/behtree.html).

Debugger and Profiler Workflow Updates

Debugger and profiler setup is now available directly from the editor top panel via dedicated indicators and settings popups. You can enable either tool and apply changes without editing the script required or switching launch presets.

However, some steps are still manual: for debugging you still need to attach the Das debugger from VS Code after enabling it, and for profiling you still need to connect the external daProfiler app to capture data.

See the documentation for details: - Debugger: https://docs.edenspark.io/getting_started/debugger.html - Profiler: https://docs.edenspark.io/getting_started/profiler.html

Dynamic GI

GI is now fully dynamic: whenever you place or destroy static meshes or move lights, it will quickly and smoothly catch those changes without (almost) additional performance cost.

Also basic scene-dependent GI setup is now available through the HDGlobalIllumination component.

Launcher

The launcher now supports reading and writing comments on published games. Open any game's page and click the comment icon to view the full comment thread. You can post new comments, edit or delete your own, and like or dislike others

The launcher now includes a dedicated Create tab. Creation-focused content has been moved out of Home, so My Games and Recycle Bin now live in Create for a clearer separation between discovery and project management.

EdenSpark MCP Server

EdenSpark now includes a built-in MCP (Model Context Protocol) server that allows AI tools like Claude Code to interact with the running editor and game in real time. The server provides scene inspection, input simulation, screenshot capture, and game control tools for an external AI agent.

Mesh Optimizer & Simplifier

A new mesh optimizer is now part of the model build pipeline (always enabled). It improves vertex cache locality without altering mesh topology, delivering up to 30x rendering speedup in benchmark tests.

Also new: an optional mesh simplifier with four reduction levels — `None`, `Soft` (2x), `Medium` (6x), and `Aggressive` (10x) — for use cases where polygon count matters more than full fidelity.

Physics callback

Added callback for physics simulation - global ``on_fixed_update`` function. It is called before each physics step, use it to do all physics calculations - for example, apply forces.Here's a diagram how ``on_fixed_update`` might be called:

Note that ``get_delta_time`` inside this callback will return physics fixed delta time.

Shader Graph

The new Shader Graph editor lets you create and edit custom materials by connecting nodes — no shader code required.This is an experimental feature and we'd love to hear your feedback. Future updates will bring an expanded node library, improved editor UX, runtime previews, and more.

An example of a dissolve shader built with EdenSpark's Shader Graph.

Volumetric Clouds & Sky Settings

Now in HD Renderer you can enable volumetric clouds and tune sky appearance using the new HDSky component.

In addition the HDSkyOrigin component allows you to set positions for different parts of the sky.

SVG Format Support

EdenSpark now supports `.svg` files as textures. SVGs are rasterized once at their default resolution during the asset build — you can use them just like `.png` or `.jpeg` files. Dynamic (runtime) rendering is not supported yet.

Editor UI/UX Improvements

The file browser now switches to a compact list view when the icon size is set to minimum — making it easier to navigate large asset lists.

We now support focus on the node (inspector) and the asset (importer) independently. You can edit them side-by-side.
