Fab's August freebies expire Tuesday — what breaks outside Unreal
Fab's second August giveaway (Aug 11-25) includes a free UE5 cabin kit. Here is exactly what breaks moving it to Unity or Godot: Nanite LOD swap on export and a 100x unit scale mismatch, plus the fix for both.

Why GPU instancing does nothing for scattered GLB props in URP
Unity's Enable GPU Instancing checkbox is a no-op under URP once the SRP Batcher claims the draw path. Here's why free GLB props import that way, when instancing actually wins, and how to force it with Graphics.R
Blender 5.2 LTS: EEVEE gets 2x faster, two things break on upgrade
Blender 5.2 LTS shipped July 14, 2026 as the first LTS of the 5.x line: EEVEE instancing is up to 2x faster and the Python API held steady, but a renamed Geometry Nodes menu and new Cycles X defaults will catch upgraders
glTF 2.1 is coming: what actually changes for your GLB files
Khronos announced glTF 2.1 on June 11, 2026 — a 64-bit GLB format, embedded thumbnails, and multi-file scene composition. Here's what's confirmed, what's still a proposal, and what actually changes in your ex
Godot 4.5 GLB reimport renames nodes and breaks materials
Godot 4.5 and 4.6 can rename GLB nodes and silently drop their materials on reimport - a naming_version regression tracked on Godot's own issue tracker. Here's the exact Advanced Import Settings fix, plus the emb
Load GLB files in Three.js: Draco, KTX2, and animations in 2026
