EdenSpark Update 0.0.5.7

Inertial Blending in Animator

The Animator component now supports inertial blending — a technique that produces smooth, natural-looking transitions between animation states without requiring explicit transition clips. Instead of cross-fading linearly, inertial blending preserves the momentum of the current pose and decelerates it organically into the target animation, eliminating the stiff "pop" that is typical of linear cross-fades.

Bloom in Standard Renderer

Standard Renderer now supports the bloom effect. With the new Bloom component you can make your objects glow. The component can also be used to tune bloom in HD Renderer.

Blur in Standard Renderer

Now you can blur the frame in Standard Renderer by using the new Blur component. Together with rendering into a render target, it can be used for blurring backgrounds in your games. Currently the component works only in Standard Renderer because HD Renderer doesn't support multi-camera rendering without which the component is almost useless.

Collider editing improvements

Editing colliders in the scene editor is now more reliable: several issues that could cause unwanted shapes to appear, incorrect debug bounds, and lost edits have been addressed. The currently edited collider is also highlighted in the viewport so it is easier to see what you are working on.

Cube Sphere is now the default sphere shape

Cube spheres are now the default when adding a sphere primitive to the scene. Compared to the classic UV sphere, a cube sphere distributes vertices and UV space more evenly across the surface — a de-facto industry standard that works better with textures, normal maps, and subdivision. UV spheres are still available as an alternative.

Realistic water in HD Renderer

Now when using HD Renderer you can add realistic water to your scene using the new HDWater component. It's represented by an infinite plane with a water surface simulated on top and underwater rendering enabled below. Right now it's in progress, with heightmap, flowmap and effects to be added later.

Launcher

The Home tab now displays games in a grid layout instead of a horizontal scroll area, making navigation easier on both mouse and gamepad. Recent Games shows the 12 most recently played titles, with the rest available under Other Downloaded Games. User projects now use a similar grid.

MCP tools for editor automation

A batch of new MCP tools makes it possible for an AI agent (or any MCP client) to inspect the scene and drive the editor end-to-end - without touching the UI.

Pixel shaders in Daslang

You can now write custom pixel shaders directly in Daslang. Create a .shader file, choose it in material Importer window and then attach this material to mesh.

Properties declared in the var {} block appear as per-material sliders and color pickers in the editor. The @color annotation switches the field to a color picker.

Shaders have access to geometry data (worldPos, worldNormal, viewDir, uv, localPos), global scene inputs (g_Time, g_LightDirection), and a set of built-in operations:

• Surface — fresnel(power, normal, viewDir)
• Noise — noise(float2), noise(float3) — returns values in 0..1
• Utility — remap, smooth_step, step, one_minus, saturate
• Textures — tex2d(sampler, uv), declare as myTex = Sampler2D("path/to.png")
• Math — all standard functions (sin, cos, lerp, pow, abs, frac, floor, ...) overloaded for float through float4

A library of ready-to-use example shaders is included: hologram, dissolve, iridescent, toon/cel-shading, lava, water, force field, triplanar, fresnel, outline, burn, freeze, electric, and more. A separate set of 2D (screen-space) shaders is also available.

Prefab updates

Now "Add empty parent" and "Make prefab root" are allowed for all nodes. No inherited prefabs or nested prefab instances will break - go wild! The engine will handle it.

Format of prefab serialization was tweaked to be simpler and shorter. To automatically migrate all prefabs in the project, use Edit -> Migrate prefabs, or just resave them by hand.

Strudel: pattern-based music engine (experimental)

Daslang's strudel implementation is now available in EdenSpark for procedural and live-coded music. Describe rhythms, melodies and sound patterns with a compact mini-notation DSL.

This implementation extends original strudel.cc with such features as ability to use SF2 SoundFonts and binaural HRTF positioning.

Strudel functionallity is experimental and still under development, so use with caution.

Translucent surfaces

You can now create leaves, curtains or any other thin surfaces with light passing through them to the back side. The amount of light passing is set by the new translucency property in standard_diffuse, standard_specular and standard_metallic shaders. The feature works in both renderers, but HD Renderer simulates subsurface scattering in addition. We also renamed TransparencyMode.Translucent to TransparencyMode.AlphaBlend to avoid confusion. The old value is preserved as an alias for compatibility, but prefer TransparencyMode.AlphaBlend in new code. Material files are not affected.

Converter from Unity game engine to EdenSpark

We've released our internal tool for converting Unity projects to EdenSpark. You can install it as a Unity package from this repo. Well, for now its capabilities are very limited, but we'll keep improving it! Keep an eye for a future devlog. Note that the converter isn't technically a part of EdenSpark - it's an external tool that we'll update independently of the release cycle.

Welcome tab in the editor

A new Welcome tab is shown in the editor when the app is stopped. It serves as a quick-start hub with shortcuts to create a new scene, open main.das, and jump straight to the documentation, EdenSpark website, Discord and Telegram channels.

📐 API Changes

Daslang: named tuples must be explicit

Breaking change. Named tuples in Daslang now require explicit field names on construction, and mixing named and unnamed fields inside the same tuple is no longer allowed.

Before:

After:

DirectionLight → DirectionalLight

DirectionLight has been renamed to DirectionalLight for consistency with the rest of the component naming. The old names are kept as aliases, so existing projects keep working with no changes — but please prefer DirectionalLight in new code.

Cleaner physics API

Physics API has been refreshed — the rigid_body part in function names was redundant since the first argument is already a RigidBody, so it was dropped for cleaner call sites.

apply_rigid_body_impulse, apply_rigid_body_angular_impulse, apply_rigid_body_force, apply_rigid_body_torque, get_rigid_body_velocity_at are deprecated. Use the shorter apply_impulse, apply_angular_impulse, apply_force, apply_torque, get_velocity_at instead.

Pixel shaders in Daslang

Some shader graph nodes have changed their input list. Existing shader graphs that use these nodes must be updated manually.

TransparencyMode.Translucent → TransparencyMode.AlphaBlend

TransparencyMode.Translucent has been renamed to TransparencyMode.AlphaBlend to avoid confusion with the new translucency property in materials. The old value is preserved as an alias for compatibility, but prefer TransparencyMode.AlphaBlend in new code. Material files are not affected.

🔧 Improved

• Stale cache files for assets that no longer exist are now automatically removed from .project/cache/res/, keeping the cache folder lean over time
