Picasso 0.3.0

3D models

• A new 3D section: Generate Model, 3D Preview and Export Model. Generate Model builds a 3D model on this computer through ComfyUI. The inputs you connect choose how: a prompt alone (Picasso makes a picture first and shows it as the Source image output), one Image, or Front plus Left, Back and Right views. Slice a character turnaround sheet and connect its four views to get the best shape.
• Three local models: Pixal3D (textured, from one image or several views), TRELLIS.2 (textured with PBR maps, one image) and Hunyuan3D 2 (shape only, lighter, one image or several views). The Local preset picks the best one that fits your inputs. Settings: Texture, Face limit, Seed, and Quality, Shape detail and Texture size under Advanced. Download Missing Files fetches the model files.
• 3D Preview and every model result show the model on the node. Move the pointer over it to turn it, or double-click (or press Space) to open the full-screen viewer with reset view, wireframe, texture on or off, studio or neutral lighting, a dark or light background, and face and vertex counts.
• Export Model saves a GLB or an OBJ (with its material and texture pictures). FBX needs Blender and comes with the Blender agent.
• Mesh tools that take a 3D model and give one back: Decimate (faces or a share of them), Remesh, UV Unwrap, Smooth Normals, Rotate and Merge. They run on ComfyUI's own mesh nodes and keep the shape only, so the texture is dropped.
• A new starter workflow, Character to 3D: a character sheet, cut into four views, built into a 3D model.
• The assistant knows the 3D nodes.
• Cloud 3D through Tripo. Add a Tripo key in Settings, Cloud (Check Key reads your credit balance and costs nothing). Best uses Tripo H3.1 (detailed and textured), Fast uses Tripo P1 (low poly), and Tripo P2 (low poly) is in the model list. Tripo takes a prompt directly, so there is no starting picture step, and the Source image output is Tripo's preview picture. All three take a prompt, one image or several views. Face limit, geometry quality and texture quality are model settings. The assistant asks before a paid run and the Run tab shows the estimate in credits and dollars. Tripo cannot cancel a running model: Stop ends the wait, and the model may still finish and use credits. Quad meshes are not offered because Tripo returns them as FBX; results are always GLB.

Slice and Ask AI

• Auto Slice on the Slice node: choose Auto Slice…, say how to cut the picture (for example "four views, left to right: front, right, left, back") and an AI model that can read pictures draws and names the boxes. Picasso finds the separate figures first, so the boxes fit them closely. Boxes that keep their names keep their connections, and one undo puts the old boxes back.
• A slice can be flipped horizontally or vertically. Use it when a character sheet has two right views and no left one; Auto Slice can do it for you.
• Ask AI… when you right-click a node or the canvas. The selected nodes, with their settings and connections, go to the assistant with your request, for example "make the prompt more cinematic". On the empty canvas, new nodes go where you clicked. You can attach pictures and video.
• Auto Slice and Ask AI use the same box as the assistant chat, with a model picker that remembers your choice for each.

Fixes

• Buttons in the top bar of full-screen editors and viewers (such as Presets in the slice editor) sometimes did not respond to clicks.

Picasso 0.2.0

Edit part of an image

• A new Mask node and a mask editor. Choose Paint Mask… on Edit Image or a Mask node to paint over the part of an image that may change, with a brush, eraser, rectangle or lasso. Brush size, feather, invert, clear, show or hide the mask, and undo and redo work inside the editor.
• Edit Image has an optional Mask input. Only the masked area changes, and the rest of the image is kept exactly as it was. Use it to change one part of a picture, or to remove an object.
• A mask can come from any node. A picture connected to a Mask input is read as a mask: a cut-out from Remove Background uses its transparency.
• A new Outpaint node extends an image past its sides by the number of pixels you choose and fills in the new area.
• Masked edits run locally with FLUX.2 [klein] 9B, FLUX.2 [klein] 4B and Qwen-Image 2.1. A model that cannot use a mask is marked in the model picker, and a run stops with a message instead of changing the whole image.

Download models on another computer

• Download Missing Files now works for a ComfyUI on another computer, such as a Runpod pod. The server downloads the files itself, straight from Hugging Face, so nothing passes through your computer. Progress, pause, resume and cancel are in the Jobs drawer, and the node shows the model as installed when it is done.
• It needs a small helper installed on that server once. Settings, Local Models shows whether it is there, and Download Missing Files shows a one-line command to copy, a link to the setup steps and a Check Again button. The helper is in comfyui/picasso-remote, adds no nodes and needs no extra packages.
• The helper only downloads from Hugging Face and GitHub, only into ComfyUI's model folders, and never replaces a file that is already there.
• Gated Hugging Face files on another computer need your token, which Picasso sends only if you turn on Send my Hugging Face token to this server for that server. It is off by default.
• Files that need a sign-in (Civitai) are still added by hand. For another computer, Picasso names the exact folder on the server, such as models/loras/name.safetensors.

Picasso 0.1.0

The first Windows release. Picasso is a desktop app for making images and video by connecting steps on a canvas. Models run on your own computer through ComfyUI, or in the cloud through fal.

Get started

• A Get Started checklist walks you through connecting ComfyUI, checking which local models you have, and trying a starter workflow. Choose Help > Get Started to open it again.
• Three starter workflows: Quick Start, Image to Video, and Edit with a Reference. Choose File > New from Starter.
• Picasso keeps working when ComfyUI is not running. Nodes that need it tell you and offer Connect ComfyUI.

Make images and video

• Generate Image and Generate Video, with Fast, Balanced, Best and Local presets. The Local preset uses the best model your ComfyUI has.
• Edit Image, Upscale, Remove Background, Crop, Resize and Slice, with full-screen editors for Crop and Slice.
• Extract Frames, Trim Video, Join Videos and Extend Video. The video tools are included, so there is nothing to install.
• Image and video viewers with zoom, compare, frame stepping, loop and speed.

Keep your work

• Every run is saved as a version. Unchanged nodes are reused, and you can switch to an older version at any time.
• Jobs for video keep running when you close Picasso, and Picasso picks them up when you open the project again.
• A project is a folder on your computer. Nothing is uploaded unless you run a cloud model.

Models

• Settings > Local Models shows each model, what it needs, its size, its license and how fast it is. Download Missing Files fetches what a model needs into your ComfyUI, with a size check first, progress, pause and resume.
• Model packs add models, presets and ComfyUI templates. Install a pack from Settings, turn it off or remove it.
• A ComfyUI on another computer works too. Add its address in Settings.
• Cloud keys are encrypted with your Windows account and are never shown again.

Assistant

• Describe a workflow and the assistant builds or changes it for you. It can use Claude, other cloud models, or a model running in Ollama on your computer.

Install and update

• The installer puts Picasso in your user folder (no administrator needed) and lets you choose another folder. Uninstalling removes the app and keeps your settings and projects.
• Picasso checks for new versions in the background, downloads them, and shows Restart to Update when one is ready. Turn this off in Settings > About.
• The installer is not signed yet, so Windows may show a SmartScreen warning. Choose More info, then Run anyway.

Licenses

• Picasso includes FFmpeg, built under the LGPL. Settings > About > Licenses lists everything Picasso is built on, with a link to FFmpeg's source.
• Video is saved as H.264 through Windows Media Foundation. Files play in almost every player, with a slightly larger file than a high quality x264 encode.
