Aiming Helper earns its place in the Blender extensions library as a focused viewport tool: a small 5.1 KB add-on that does one job — checking sight alignment on weapon models — with a clear green/red overlay and an adjustable threshold.
Aiming Helper is a Blender add-on by Hartface built for visualizing and aligning sights on weapon models. It targets game asset artists who need to confirm that eye, rear sight, front sight and target sit on a single line. The tools live in the N panel of the 3D viewport, under a dedicated Aiming Helper tab.
Setup runs through a Pick button next to each point. Clicking turns the cursor into an eyedropper; clicking a mesh surface anchors the point in local space so it follows the model as it moves. Start Visualizing draws the overlay: a line through the set points that reads green when aligned and red when not, deviation lines from each sight to its ideal position, angle readouts in degrees at intermediate points, and corner status text showing the aligned or misaligned state with exact deviation. An Alignment Threshold setting controls how strict the check is.
You don't need all four points to begin — two are enough. Re-clicking Pick on any slot repositions it. The add-on is licensed under the GNU General Public License v3.0 or later and works with Blender 4.2 LTS and newer.
Aiming Helper is best for game asset artists working on weapon models who need to verify that eye, rear sight, front sight and target are properly aligned in Blender.
Aiming Helper is completely free to download and use.
Aiming Helper is compatible with Blender 4.2 LTS and newer, so it runs on the current LTS release and later builds. It installs as a Blender add-on and requires no special permissions. The current version is 1.0.1, updated in June 2026, and that release changed its '3D View' tag to 'Object' and added a website entry to the blender_manifest. For older Blender versions there is no listed support, so check the developer's page before installing on anything below 4.2 LTS.
Aiming Helper installs like a standard Blender extension: drag and drop the add-on into Blender, or download it and use Install from Disk. It carries a compact 5.1 KB footprint and requires no special permissions. Once enabled, open the N panel in the 3D viewport and switch to the Aiming Helper tab to reach its controls. The add-on is released under the GNU General Public License v3.0 or later, and issues can be reported through the developer's GitHub page if anything doesn't behave as expected.
Aiming Helper works from the N panel in the 3D viewport, where you click Pick next to each point — Eye, Rear Sight, Front Sight and Target. Your cursor becomes an eyedropper, and clicking a mesh surface anchors that point in local space so it moves with the model. You don't need all four points to begin; two are enough to start visualizing. Hit Start Visualizing to see the overlay, and re-click Pick on any slot to reposition a point whenever you need.
Aiming Helper is listed as free here in the catalog, and it is distributed under the GNU General Public License v3.0 or later. It requires no special permissions to install. For the current licensing terms and any future changes, check the developer's page. The add-on has been downloaded a couple of hundred times and sits at version 1.0.1, updated in June 2026, so the licensing details there reflect the most recent release.
