MoonRay 2.40: New ImGui UI and Better Light Path Tools
DreamWorks Animation has released MoonRay 2.40, upgrading its open-source production renderer with a much-improved light path visualizer and a new Dear ImGui-based GUI prototype. The refreshed tools add pixel inspection, snapshots, a status bar, and cleaner path visualization for easier lighting and debugging. This update also delivers a long list of stability and rendering fixes, from importance sampling and bounding boxes to USD normals and Hydra crashes, making MoonRay more reliable for high-end pipelines.
Solving Vulkan’s Extension Explosion with VK_EXT_descriptor_heap
Vulkan’s working group is tackling the long-standing “extension explosion” problem by introducing VK_EXT_descriptor_heap, a clean-slate replacement for the old descriptor set system. Instead of layering more incremental fixes, this EXT defines a new subsystem where descriptor heaps are just memory and descriptors are just data, much closer to console-style APIs. The extension has broad industry backing and is intended to become future core Vulkan. Developers are encouraged to adopt it now and provide feedback within the next nine months.

What We Learned From Playtesting Our Idle MMO After 4 Weeks
After just 4.5 weeks of development, this small studio ran a live playtest for their incremental game “MMO 98” and shares what actually happened. They break down the three kinds of feedback you’ll get, how quickly responses hit diminishing returns, and why you must filter “noise” to protect your vision. The team also reveals their biggest regret—skipping analytics—and explains why they’re racing into the next Steam Next Fest despite the risks.
How Shadowglass Achieves Stable First-Person Pixel Art in 3D
First-person pixel art usually falls apart under camera movement, turning into shimmer and blur rather than crisp retro charm. The author reverse-engineers a viral “Shadowglass” effect by rendering the world into low-res cubemaps and reprojecting them in screen space using a depth cubemap and raymarching. This keeps pixels stable, preserves distant details, and smoothly blends between cubemaps as you move. The article walks through the logic, pseudocode, Unity setup, and the performance challenges of making it production-ready.
