Faster, wider, cleaner: KIRI Engine 4.0 drops mobile scan limits

27.08.2025
KIRI Engine 4.0 slashes scan time, boosts photo limits, adds AR guidance and AI PBR and plus free users enjoy unlimited exports. Production-ready, at last.

KIRI Innovations has shipped KIRI Engine 4.0, a major update to its mobile 3D scanning app for Android and iOS. The release focuses on faster photogrammetry, higher capture limits, AI-based texture generation, and new freedoms for Basic users.

Faster photogrammetry, cleaner meshes

Photo Scan mode now processes data in about two minutes per scan, compared to nearly ten in earlier versions. The update also improves handling of low-texture surfaces, producing more stable reconstructions with fewer artefacts.

Augmented reality for capture coverage

A new AR mode projects captured camera positions into 3D space, allowing users to spot gaps in coverage and reshoot missing angles. This aims to reduce reconstruction errors caused by incomplete data.

Raised photo upload limits

The app now supports larger capture sets. Basic users can upload up to 150 photos per scan (up from 100), while Pro subscribers can use up to 500 photos (previously 300). This should improve detail and accuracy in complex object scans.

Unlimited exports for everyone

The former cap of three exports per week for Basic accounts has been removed. All users can now export an unlimited number of scans in standard formats including OBJ, FBX, STL, GLB, glTF, USDZ, PLY, and XYZ. This change affects both photogrammetry and LiDAR workflows.

AI-powered PBR material capture

Version 4.0 introduces an AI-driven physically based rendering (PBR) algorithm, built on a diffusion model. According to KIRI Innovations, this generates more realistic and consistent material textures directly from scanned data, reducing the need for manual texturing.

On-device full-resolution previews

The app now supports full-resolution model previews on mobile devices, enabled by a new compression method. Users can toggle textures on and off to inspect raw geometry, addressing a long-standing limitation of mobile-based workflows.

Pricing and availability

KIRI Engine remains free to download. Pro accounts cost US $17.99/month or US $79.99/year, unlocking higher photo limits and features such as 3D Gaussian Splatting (3DGS). Version 4.0 is available now for Android 7.0+ and iOS/iPadOS 15.0+ devices.

Final Note

The new release removes significant bottlenecks in KIRI Engine’s free tier while introducing AI-driven texture tools for Pro users. As always, readers should verify output quality and workflow compatibility in test projects before adopting the tool for production.
