TopMod vs MapBake

Works best for Ipad. TopMod is a topological mesh modeler for sculpting intricate, high-genus 3D surfaces right on your iPhone and iPad. Build handles, holes, and complex manifold geometry in real time, then export your creations as OBJ files to use in any 3D pipeline. A focused, self-contained tool for artists, designers, and anyone who loves the mathematics of form.

Turn images into practical, game-ready PBR material starting points directly on iPhone and iPad. MapBake prepares a source image, makes it tileable, estimates a complete material set, previews the result in 3D, and exports the conventions your target engine expects. IMPORT AND PREPARE • Import from Photos, Files, Camera, Clipboard, or drag and drop on iPad • Crop, rotate, flip, correct perspective, and normalize uneven lighting • Keep the original source intact while you experiment MAKE IT SEAMLESS • Create a horizontally and vertically tileable texture offline • The tile is rebuilt from patches of your photo, joined along cuts that follow real detail, so joins stay invisible and nothing is mirrored • One control trades keeping your source's structure against mixing it more freely • Inspect any map at 1×1, 2×2, 3×3, or 4×4 with zoom and pan GENERATE A COMPLETE PBR SET • Base Color, Height, tangent-space Normal, Roughness, Metallic, and Ambient Occlusion • Useful deterministic estimates designed to be adjusted—not false claims of recovering perfect physical properties from one photo • Fast working previews with full-resolution recomputation when you export PREVIEW THE MATERIAL • Physically based RealityKit preview on a plane, sphere, cube, or rounded cube • Neutral, soft, outdoor, overcast, warm, high-contrast, and dark studio lighting • A directional key light you can sweep and lower to rake across the surface, so relief in the height and normal maps actually reads • Inspect scale, tiling, reflections, normal response, roughness, and metallic behavior EXPORT FOR YOUR TOOLS • Unity Built-in, URP, HDRP, Unreal Engine, Godot, Blender, OpenGL, and DirectX profiles • Automatic normal Y conversion, roughness/smoothness conversion, and standard packed maps • PNG output at 256, 512, and 1024 in the free app • MapBake Pro is a one-time purchase that removes ads and adds 2K/4K export, custom RGBA packing, and saved custom presets No account is required. Source images and generated materials are processed on-device and stay local unless you explicitly export or share them.
