Minimum requirements: Requires a Windows 10 or higher (64-bit) operating system with at least 32 GB of RAM, and an NVIDIA graphics card with a compute capability of 5.0 or higher and at least 4 GB of video memory, equivalent to or better than NVIDIA GeForce GTX 1050Ti.

Recommended requirements: Requires a Windows 10 or higher (64-bit) operating system with 64 GB of RAM, and an NVIDIA graphics card with a compute capability of 7.0 or higher and at least 8 GB of video memory, equivalent to or better than NVIDIA GeForce RTX 2070.

No. Using DJI Modify requires a network license, so a constant network connection is needed during the operation.

The paid version of DJI Modify supports unbinding, with a certain number of unbinds allowed per year, and the unbinding policies vary among different packages.
The trial version of DJI Modify does not support unbinding.

Currently, no. DJI Modify can only edit visible light 3D models reconstructed with DJI Terra V4.0.0 or higher.

Currently, no. Renaming the modeling results in DJI Terra will prevent DJI Modify from being able to edit the model.

Yes, but the moved project will not be displayed in the project list. You will need to import the project into DJI Modify again.

Please avoid changing the task names in DJI Terra to prevent inaccessible models and other files.

High-quality models, typically in ply or obj formats, are used for small-area adjustments such as flattening, hole filling, and texture repair.
Low-quality models, often in b3dm or osgb formats, are used for large-region adjustments like floating parts removal and water surface repair.

The prompt implies that the computer's capacity is limited and cannot load an unlimited number of high-quality models. It will appear when too many blocks are loaded. Consider the following measures:
1. It is recommended to use DJI Terra's block splitting function, and customize the edge lengths up 300×300 m.
2. Unload some of the loaded high-quality model blocks before loading new ones.
3. Save the current operation, exit the software and reopen it. Then try loading new blocks.

The floating part removal function currently operates on a “what you see is what you get” basis, which only eliminates the floating parts that are visible in the current view. As you zoom in on the model, model blocks get updated, and previously unseen floating parts will then be displayed.
Recommended workflow: select all floating parts> deselect the ones to keep > delete, so as to keep the larger visible floating parts and remove the others.

Currently, no. You can fine-tune the water surface texture in Repair mode following the water surface repair.

The current flattening function flattens the selected region based on the surrounding meshes, creating an approximately flat surface, rather than flattening them to the ground.

Vehicle recognition works best at a near-top-down view at an appropriate height. For optimal vehicle selection, adjust the view to an approximately top-down angle. You can also adjust the selected region using the Add to Selection and Subtract from Selection tools.

When DJI Modify flattens multiple blocks, it processes each block independently, which might result in height discrepancies between blocks.

While drawing a selection, you can click the Unselect button on the interface or press the ESC key to cancel the current selection.

For closed holes, hole filling can span across blocks.
For non-closed holes, which refer to partial areas of a hole manually selected by the user, cross-block filling is not supported.

DJI Modify will use a solid color for the hole filling when it cannot access the aerial images from aerotriangulation results of the region ensuring that the aerial images from aerotriangulation results are readable for texture repair.

You can modify the texture using the Repair tool.

Holes in wall surfaces might structurally resemble “tunnels” in mesh topology, which are not recognized as holes by DJI Modify.
To address this, use the Custom tool in conjunction with the Subtract from Selection function to select the surface of the tunnel-like structure for hole filling.

Different editing tools in DJI Modify apply to either high-quality or low-quality models, and the process called “rendering” in modeling and film industries is essentially synchronizing the modifications across both types of models in DJI Modify.

The export speed depends on whether you've performed model editing operations. If so, DJI Modify needs to perform a rendering process; if not, it directly exports the model, which is faster than rendering.

DJI Modify uses an auto-save strategy, which executes auto-saves upon exiting a project, unloading high-quality models, and before rendering and exporting model to be exported to prevent potential progress loss.

DJI Modify supports multiple undos for low-quality models, with a default maximum of 30 undos that adjust according to available computer memory.
For high-quality models, if no mesh adjustment has been made, the rules for undos are the same as for low-quality models; however, if any mesh adjustments have been made, the default number of undos is one.

A historical version is a backup of your current project at a particular point in time.

DJI Modify automatically saves a version before rendering whenever the user starts a rendering process.

Upon clicking export, DJI Modify defaults to exporting the 3D model in b3dm, osgb, ply, obj, and s3mb formats.

The coordinate system of a model exported from DJI Modify is consistent with that upon import. However, DJI Modify does not currently support 3D models that had their coordinate systems adjusted through seven-parameter transformations.

Currently, no.

Model data from the Chinese mainland is stored on servers located within the Chinese mainland. Model data from other countries/regions is stored on US servers.

Coordinate information is removed before uploading models to the cloud through DJI Modify.

For ordinary scenarios, it’s recommended to customize the block size under the settings “3D Model > Advanced Settings > Region of Interest (ROI)/Block > Block Splitting Options” with sides smaller than 300×300 m.
For circle or close-range scenes, there's no need to adjust block splitting settings.

Press and hold the scroll wheel of the mouse to rotate the model; press and hold the right mouse button, or hold down the spacebar and press and hold the left mouse button to drag the model.
