Nodes reference

Marso Studio is built around nodes. Each node is one step — generate or load an asset, generate or edit an image, apply materials. Connect a node's output to the next node's input to build a pipeline, or start from a template that wires a pipeline up for you.

Nodes are grouped into Image, 3D, Utility and Templates.

Image

Image Upload

Upload an image to use as a starting point in your pipeline.

• Input: image file
• Output: image
• Cost: no credits

Image Generation

Generate an image from a text prompt.

• Input: text prompt
• Output: image
• Cost: 1 credit

Multiview

Generate a multi-view set of an object from a single image — useful for a stronger 3D reconstruction.

• Input: image
• Output: multiple views of the object
• Cost: 4 credits

Image Edit

Edit or refine an existing image with a prompt.

• Input: image + prompt
• Output: edited image
• Cost: 1 credit

3D

Load 3D Model

Upload your own 3D asset (.glb, .usdz or .fbx). See 3D file support.

• Input: 3D file
• Output: 3D model
• Cost: no credits

Generate 3D Model

Turn an image into a 3D mesh.

• Input: an image, or a multi-view set
• Output: 3D model
• Cost: 4 credits (single image) · 5 credits (multi-view input)

Utility

Generate PBR Textures

Run I2M to predict a full PBR material stack — albedo, metallic, roughness and IOR — for a textured mesh.

• Input: textured 3D model
• Output: textured 3D model + individual PBR maps
• Cost: 10 credits

Templates

Pre-built pipelines that wire nodes together for common journeys:

• PBR Pipeline — Load 3D Model → Generate PBR Textures. See Apply PBR to your own model.
• Generate 3D Pipeline — Image Generation → Generate 3D Model → Generate PBR Textures. See From image to textured 3D.
