BlenderGIS Blender 5 Compatibility Fixes (2026)
Blender 5.x is here, and like every major Blender release, it broke a few things for addon developers. BlenderGIS — the free, open-source (GPL-3.0) GIS addon by domlysz — is no exception. GitHub issues reflect a cluster of Blender 5.x reports: cache folder errors, Get OSM failures, and image handling problems.
This page collects the known Blender 5.x issues, which version fixes each one, and how to work around them if you cannot update yet. The addon officially supports Blender v2.83 through 4.x/5.x, and the current release is v2.2.15 (2025-12-20) — always check your version first, because several of these bugs are already fixed.
Known Blender 5.x issues and their fixes
1. Cache folder TypeError. On Blender 5.x, some users hit a TypeError when BlenderGIS tries to set or read its cache folder path. The symptom: operations that need the cache (basemaps, tiles) fail with a Python type error instead of working. Workaround: open the BlenderGIS addon preferences and set the cache folder path manually to a simple, existing directory (no special characters, no network paths). Fixed in: newer releases addressed cache path handling on Blender 5.x — update to v2.2.15 before doing anything else.
2. Get OSM errors on Blender 5.2. Several GitHub issues reflect Get OSM throwing errors specifically under Blender 5.2, even when the Overpass API is reachable and the same query works on Blender 4.x. The failure is in the addon’s request/parsing path under the new Blender Python environment, not in your query. Workaround: test the same small-area query in Blender 4.x/LTS to confirm it is version-specific, then either stay on 4.x for OSM imports or update BlenderGIS to the latest release. Fixed in: compatibility fixes for Blender 5.x shipped in recent releases — check the release notes for v2.2.15.
3. ImageIO-related problems. Blender 5 changed parts of its image handling stack, and BlenderGIS code paths that touch image I/O (basemap tile assembly, certain imports) can break or behave differently. Symptoms range from blank tiles to outright errors during basemap import. Workaround: if basemaps fail on 5.x but work on 4.x, use 4.x for the import step and append the result into your 5.x scene. Fixed in: image handling compatibility was part of the Blender 5.x support work in recent releases — update first, then report if it persists.
4. General API breakage on new Blender versions. Blender’s Python API changes every major release, and addons compiled against older assumptions throw attribute or type errors. If you see an error mentioning a missing attribute or an unexpected type right after upgrading Blender, it is almost certainly API drift. Workaround: keep a portable Blender 4.x install alongside 5.x for production GIS work until the addon catches up. Fixed in: ongoing — each BlenderGIS release notes which Blender versions it targets.
How to stay working: update strategy for 2026
Blender 5.x compatibility is a moving target. Here is the practical strategy:
- Update BlenderGIS first, always. Run the BlenderGIS update steps and get to v2.2.15 (2025-12-20) before troubleshooting anything. A large share of “Blender 5 broke BlenderGIS” reports are simply old addon versions.
- Keep Blender 4.x LTS as a fallback. For production work with deadlines, do your GIS imports in the last 4.x LTS, where BlenderGIS behavior is long-settled, and do your rendering in 5.x. The .blend handoff between versions is painless compared to debugging API errors mid-project.
- Isolate the failure. Before blaming the Blender version, reproduce the error with the smallest possible input: a tiny basemap area, a tiny OSM bbox. If small inputs work on 5.x, you have a data-size problem, not a compatibility problem — see the troubleshooting hub.
- Report with version numbers. If you file an issue, include your exact Blender version (e.g., 5.2.x), your exact BlenderGIS version, your OS, and the smallest steps to reproduce. “It broke on Blender 5” without versions is not actionable for the maintainer.
The pattern with every Blender major release is the same: a burst of compatibility issues, then addon updates that close them. BlenderGIS has a history of catching up — staying on the latest release is the single highest-leverage thing you can do.
Frequently asked questions
Is BlenderGIS compatible with Blender 5?
The addon supports Blender v2.83 through 4.x/5.x, but early Blender 5.x releases exposed several bugs (cache folder TypeError, Get OSM errors on 5.2, ImageIO issues). Most are addressed in recent releases — update to v2.2.15 (2025-12-20) first.
What causes the cache folder TypeError on Blender 5?
BlenderGIS fails to set or read its cache folder path under Blender 5.x, raising a Python TypeError. Manually setting the cache path in the addon preferences to a simple existing folder works around it, and newer releases fixed the underlying handling.
Get OSM works on Blender 4.x but fails on 5.2. Why?
The failure is in the addon’s request/parsing path under Blender 5.2’s Python environment, not in your query or the Overpass API. Update BlenderGIS to the latest release, which includes Blender 5.x compatibility fixes.
Should I downgrade to Blender 4.x for GIS work?
For deadline-driven production work, yes — keep a portable Blender 4.x LTS install for GIS imports and do rendering in 5.x. BlenderGIS behavior on 4.x is long-settled, which removes version uncertainty from the equation.
How do I report a Blender 5 bug usefully?
Include your exact Blender version, exact BlenderGIS version, OS, and the smallest reproduction steps. Check the GitHub issues page first to see if the same failure is already reported.
Will old BlenderGIS versions work on Blender 5?
Unlikely. Blender’s Python API changes each major release, and old addon versions throw attribute or type errors from API drift. Update to the current release (v2.2.15) rather than debugging an outdated version on a new Blender.
