What it does
Generative content platform aimed at game studios: style-trained models, concept art, marketing creatives and asset variations with team workflows.
Generates persistent 3D worlds from text, images, video, 360° panoramas or blocked-out 3D layouts. Exports Gaussian splats and GLB meshes, and records camera flythrough videos.
Verdict
For studios that want style-trained generation with no per-seat fees; the pricing page lists a commercial licence for all users.
For blocking out explorable environments or flythrough shots; exports go to Unity/Unreal via Gaussian-splat plugins, and commercial rights are listed on Pro.
