Yugma vs Spline: AI scene composer or 3D editor with AI?

# Pricing snapshot

# The category gap: scene composer vs editor with AI

The fastest way to understand the two products is to type the same prompt into each. Try "a mid-century living room with a low coffee table, two armchairs, and warm evening light". In Spline, the AI happily generates one chair. In Yugma, the AI Director plans the room, places six objects on a coherent floor plan, and sets the HDRI to a warm interior — all from one sentence.

That difference is structural. Spline's AI operates at the asset level: generate one mesh, place it in the canvas. Yugma's AI operates at the scene-graph level: compose a graph of objects with spatial relationships, then commit them in one transaction. Both are valid; they solve different problems.

# Where Spline is stronger today

• Animation timeline. Spline's keyframe + states + events system is mature and battle-tested for product micro-interactions.
• Code export & embedding. Long-standing React/Vue/Webflow exports and a strong embed story for marketing pages.
• Asset community. Public Spline community + remixable scenes is larger, with more reference material.
• Mobile apps. iOS + Android editors. Yugma is browser + PWA only.

# Where Yugma is stronger today

• Multi-object scene composition. Yugma's AI plans, places and links many objects in one prompt. Spline AI is one asset at a time.
• Real-time collaborative AI. Two people, one scene, AI in the chat — live. Spline collab is non-AI.
• Scene-graph + structured tool calls. Every AI action is a typed mutation (add_object, apply_material_preset, generate_layout, …) which means full undo/redo and a clean React Three Fiber export.
• Sketchfab + Meshy import inside the AI loop. Ask for "a tan velvet armchair" and the AI fetches a real model rather than generating an approximation.
• Free tier with no watermark on exports. Spline free tier watermarks GLB / PNG.

# Workflow side-by-side: building a furnished bedroom

In Spline: create new file → drag bed primitive → adjust → drag side table → adjust → drag lamp → use AI to generate a rug → place → manually compose lighting → save. Roughly 30–60 minutes to a credible draft.

In Yugma: open studio → type "Draft a 12×14 ft bedroom, mid-century modern, north-facing window, queen bed, two side tables with reading lamps, an oak floor and a low-pile rug" → AI Director places ten objects in one tool-call batch → user edits the rug color via chat → exports GLB. Roughly 90 seconds to a credible draft.

Spline wins when you want pixel-perfect control over individual elements. Yugma wins when you want a full scene fast.

# When to pick Spline

• You need a polished animation timeline more than scene composition.
• You're embedding a single hero asset on a marketing page and want code export.
• You design solo and prize asset-level control over speed.
• You already have a Spline workflow your team is fluent in.

# When to pick Yugma

• You want to draft scenes — interiors, events, product staging — from a sentence.
• You collaborate live with clients or teammates and want AI in the same room.
• You're a React Three Fiber developer who wants AI to operate the scene graph you'd otherwise hand-code.
• You don't want a watermark on free-tier exports.

# Migrating from Spline

Spline exports GLB. Drag the GLB into Yugma's library panel and it lands as a Sketchfab-style import — fully editable in the AI chat. You don't lose your work; you upgrade the editing layer.
