I have tried it but when I import the model in any other 3D modeling software it is still in meters (you can easily check it by taking a measurement). If a measurement in Reality Capture is, say, 100 mm, in any other software it’s 0.1 (so 100 mm, but expressed in meters). In order to have the file in meters, you should scale it by a factor of 1000 in the Export Mesh panel.
You can declare the Projects Scale Units in Project Settings. This should also affect imports. With Imports, I always load one of a set of meshes, and see how that ‘fits’ in the scene, using a Static Character for scale.
If the scale is way off, simply adjust the Import Uniform Scale 0.001 scales something exported as Millimetres to Meters. That setting is sticky for the session.
Same with the Orientation, where some models have their Y and Z swapped.
Hi,
Thank you for your reply! I’m not sure I understand your instructions on how to proceed. My concern is more when you export from Reality Capture. If you go under “Workflow” > “Setting” > “Coordinate System” > “Output Coordinate System,” you can import a laboratory preset that is in millimeters (mm), as shown in the link I shared. However, when I export and open my model in Meshlab or Blender, I get my model in meters instead of millimeters.
Is there any way to solve this?
Thank you again! So, in the case of Blender, you have system units set to meters but you want to display lenghts in millimeters.
My question was more that you don’t actually export from Reality Capture in millimeters -even if you choose so in the settings- but you still have meters.
You just work with that model in the selected units. This doesn’t mean that the units will be implemented in the export, as each software uses different units, so you need to consider this.
The model is scaled properly and if it has 100 mm or 0.1 m, it is the same size of the model. Then you need to set the viewer units properly.
Or, as you wrote, you need to use scaling factor in the export settings.
I understand now. The model will still be in meters. I was just confused because you can choose millimeters for the output in RC, but the model will still be in units that correspond to meters.
OK, I checked it again and you need to have georeferenced model in that local coordinate system and then export the model with Coordinate system set to Project output:
When the model is only scaled using the distance, there is no option to set Project output setting, only Grid and Same as XMP, and therefore the model is exported in meters instead of millimetres.
