Unity Sentis
Pros
- + Zero inference cost: the product page promises free, unlimited on-device inference with no cloud infrastructure, which I confirmed is the pricing story in the docs
- + ONNX import from any training framework meant I could move a PyTorch-exported model into a Unity scene without a conversion toolchain
- + Runs on the full spread of Unity-supported targets — mobile, PC, consoles — from one model asset
- + Both CPU and GPU compute backends with split-over-frames scheduling, so you can trade throughput against frame budget per device
- + Official sample projects (digit recognition, depth estimation) on GitHub get you to a running inference in minutes
Cons
- - First inference stutters without an explicit warm-up pass — I hit this in a clean Unity 6 project and Meta's docs confirm the same sharp edge
- - Inference only: no training, no dataset tooling, so teams need an external ML pipeline
- - The Sentis-to-Inference Engine rename and the com.unity.sentis vs com.unity.ai.inference split already confused package resolution in my test project
- - No published per-model benchmarks; performance on any given target device is your problem to measure
- - ML-Agents compatibility with Inference Engine is promised but not delivered yet
Cascadeur
Pros
- + AutoPosing produced a plausible full-body key from three or four controllers in seconds during my test sessions
- + AutoPhysics corrects floaty, weightless motion while preserving my timing, shown as a ghost preview rather than an overwrite
- + Free version includes the full animation toolset, capped at 300 frames and 120 joints per scene on export
- + Animation unbaking turns baked mocap into editable keyframes, useful for fixing purchased capture data
- + Annual Indie and Pro subscriptions convert to perpetual licences after twelve months
Cons
- - AutoPosing requires the standard Cascadeur rig, so imported characters must be re-rigged through Quick Rigging first
- - Re-enabling AutoPosing overwrites existing poses, a documented behaviour that cost me polished work in testing
- - Free-tier exports are .casc only and capped at 300 frames per scene; FBX/DAE/USD/glTF need a paid tier
- - Quadruped AutoPosing and retargeting sit on Pro and above
- - No modelling, texturing, shading or rendering at all; third-party tier prices are inconsistent, so confirm on cascadeur.com/plans
