What does getting a 3D asset into a game engine actually involve?
More than most tutorials admit. Actionspark covers the full pipeline — from mesh prep to runtime behaviour — without skipping the parts that usually break at 2am.
Mesh preparation
Clean topology, correct pivot points, and sensible polygon counts before anything touches an engine importer.
Material and texture mapping
PBR workflows, UV channel management, and why your normal map looks inverted in Unreal but fine in Blender.
Rigging, LODs, and runtime optimisation
Skeleton binding for animated characters, level-of-detail setup, collision mesh authoring, and draw call budgets — the decisions that separate a shipped asset from a demo asset. Each topic is grounded in specific engine contexts: Unity, Unreal, and Godot.
Format decisions
FBX vs glTF vs OBJ — when each format loses data and how to check before it matters.
Shader compatibility
Reading engine shader graphs without rewriting materials from scratch every time you switch targets.
Performance profiling
Using engine profilers to identify which assets are actually causing frame drops, not just guessing.
How the course is structured
Each module follows an asset through one complete stage of the pipeline. You work on the same file across sessions, so the consequences of earlier decisions become visible later — which is closer to how production actually runs.
Lectures are recorded and available on demand. There are no live sessions to schedule around, no cohort start dates, and no artificial urgency. Progress at whatever pace keeps the material sticking.

"The section on normal map tangent space alone saved me three days of confusion. I had been reading forum posts for weeks and none of them were as direct."
