meshloader converts your 3D and CAD data into a scene you can walk through and explore. The typical workflow: Import the model, review it in desktop mode, edit it in VR if needed, and then save it as an .ml file or share it.

The .ml file is meshloader's container format for 3D scenes: It bundles the prepared scene, its settings, and project-specific content such as fixed points or media. This ensures that a prepared scene can be reproduced exactly—including scale, lighting, and spatial arrangement.

Exactly. An .ml scene opens the same way everywhere, maintains its scale (1:1), is up to 50% smaller than the source file, and can be password-protected—it can be split up like a PDF, but only for space, machine, and motion.

Desktop (or non-VR) mode is used for preparation, quality control, and on-screen presentations. VR mode enables 1:1 walkthroughs, spatial analyses, and immersive client presentations. Both modes work with the same project.

meshloader imports common 3D and CAD exchange formats: FBX, glTF, GLB, 3DS, OBJ, DAE, USD, and IFC—without being tied to any specific authoring software. Simply export from your CAD application to one of these formats.

Yes. Variants and different project states can be imported and activated via the model selection. For a clean comparison of variants, export them all from the same coordinate system—with the same origin and the same up-axis.

The quality of the scene is determined right from the export stage: a consistent scale, a logical origin point, and clean assets reduce the need for rework. Keep a known reference dimension in the model, embed textures, and remove unnecessary small parts, duplicates, and auxiliary objects.

meshloader is designed for the 64-bit versions of Windows 10 and Windows 11. Recommended specifications include a quad-core processor running at 2.5 GHz or faster, 16 GB of RAM, and a DirectX 11/12 graphics card with 4 GB of VRAM or more.

No. Each model can also be opened and explored on a regular screen. With VR headsets, you can experience the model in an even more immersive way at a 1:1 scale—but desktop mode is sufficient for preparation and presentation.

meshloader is designed for PC VR. It supports device families from Meta (Quest), Pimax, Valve (Index/Frame), Pico, and Varjo—via the respective manufacturer’s software or SteamVR/OpenXR. Specific compatibility depends on the model, firmware, and runtime; please test your configuration before a presentation.

As a guide: Low — NVIDIA GTX 1060 or equivalent; Medium + Reflections — RTX 3060 with a Core i5 or Ryzen 5; High + Lumen GI — RTX 5070 or better with a high-end CPU. In VR, a stable frame rate is more important than maximum graphics quality — start with medium settings and increase them gradually.

Using the virtual tablet, you can access the following features within the scene: measurements, cross-sections, sun position simulation, rendering/screenshots, fixed points, audio sources, model settings, and model selection. Desktop mode offers the same core tools for preparation.

Yes. In multi-user mode (the “meshloader + MultiUser” option), multiple participants can enter the same scene—ideal for design reviews with clients, specialists, or distributed teams. Servers, access points, and access rules are configured on a project-by-project basis.

Yes. The Camera tool generates quick renderings or screenshots for documentation, approval, and presentation—which are saved in the specified destination folder. Recommendation: Use a project-specific folder and a clear, traceable file naming convention.

Yes. The sun position simulation shows light, shadows, and reflections throughout the day—in "Sky" or "Abstract" modes, with an adjustable time setting. For architectural reviews, a fixed sequence of morning, noon, and evening scenarios is ideal.

You retain your original data. Only the .ml file is shared: When you save the file, the imported 3D data is converted to the scene format—there’s no need to include the original source files. Recipients can view the scene but cannot extract the raw CAD data.

Yes. You can set a password when creating a project. Best practice: Send the file and password via separate communication channels, and before sending, verify that the scene contains only the intended models, media, and fixed points.

Yes. When you launch the program for the first time, you can use a seven-day trial or activate an existing annual license directly by clicking "Register Key." An Internet connection is required for downloading, registration, and license activation.

The software may be used on multiple computers in accordance with the applicable license terms. Before switching devices, log out of the previous device; simultaneous use is subject to the applicable license model.

There is a free version to get you started; you can find premium subscriptions and all terms and conditions on our Pricing page. The current contract and product information always takes precedence.
