Mini Paint Forge - 3D Digital Miniatures Painting App

Mini Paint Forge is a high-fidelity 3D painting tool built specifically for painting tabletop miniatures terrain and models. It brings the real hobby workflow — priming, basing, washing, drybrushing, edge highlighting, etc — together with the things only software can give you: unlimited undo, non-destructive layers, specialized multistep brushes and one-click turntable renders and timelapses to name a few.

There is already a fully working Beta that you will get early access to before the program's full release.

Paint straight onto the mesh

Mini Paint Forge is a vertex painting app, there is No UV unwrapping, no texture atlases. Drop in an STL, OBJ or GLB — including large triangle count digital sculpts — and paint per-vertex directly on the geometry. Resolution scales with your model, so detail lands where the polygons are.  This makes the painting similar to real world painting, but with new quality of life features and enhanced brushes and effects.

Here is a series of overview videos showing various features of the app:

Variety of standard and specialty brushes

Standard Brush - just like a normal paintbrush

Airbrush — soft continuous flow for zenithal glazes and gradients

Drybrush — automatically catches raised edges and sculpted texture

Wash — flows downhill into recesses and panel lines

Edge Highlighter — finds hard edges and sharpens them

Contrast / Speedpaint — pools in the cracks, pulls off the peaks

Zenithal Brush/Soft Shade/Non Metallix Metal Brush- Specialty Brushes that provide instant shadows and highlights

Camoflauge Tool - Paint several preset camoflauge patterns in your preferred colors

And many more - Directional highlighter, highlighter, marker, undershade, cell shader brush, decals, specialty eye tool, object source lighting tool, glaze, plastic tool, sheen control, smoothing, smudging, splatter and sponge effects

Prime in one click

The Priming Studio generates a regular flat prime, a zenithal highlight (light from above, shadow below), a soft shadow highlight and shade, a NMM prime, or a cell-shaded gradient, so you start every model on a proper value base instead of flat grey if desired.

Color Analyzer

Pull palettes straight off a reference photo with the Color Analyzer. so you can match colors of your favorite artist, or inspire your color palette from an inspirational painting or drawing.

Layers, recipes & real paint ranges

Non-destructive layers with opacity, visibility and blend modes (Multiply, Overlay, Screen). The Color Recipe system builds a five-stage shadow → base → highlight progression from any color, and the Paint Library allows you organize all your favorite colors. Easily editable JSON files allow for users to create there own digital paint libraries inspired from their favorite paint lines and share them with the community.

Smart Selection/Masking

Isolate pieces of the model with a click or paint on your mask. Smart Selection walks mesh connectivity and crevice boundaries to grab the logical part. Or paint your mask directly on the model to make sure your paint stays inside the proper boundary.  There is a also a procedural region generation tool that isolates pieces of the model based on geometry.

Workshop Support

Share color libraries, custom multitools, and more on the steam workshop. 
 Export & share

Save to GLB, GLTF or OBJ with real per-vertex color baked in. Render high-res screenshot PNGs, spin up looping 360° turntable GIFs/MP4s, or create a timelapse video for socials all with a few clicks. Decimate models to reduce polygon count and filesize for virtual tabletops like tabletop simulator and talespire.
