Can you add a option to select what multiscale values can be chosen?  
For example I want only 1, 1/2 and 1/4.  
I want to turn 1/8 off

Hello @rafaldrzewski,

You can change the image scale and multiscale for each project. The image scale that you select will be used during the processing. You can change it for every project and never use 1/8 if you don’t want to. For more information, visit [Menu Process \> Processing Options… \> 2. Point Cloud and Mesh \> Point Cloud](https://support.pix4d.com/hc/en-us/articles/202557799-Menu-Process-Processing-Options-2-Point-Cloud-and-Mesh-Point-Cloud)

Hello, I am fully aware of this feature BUT I don’t want to compute my point cloud several times at different image scales and then merge the point clouds together in 3rd party app.  
This should available in Pix4DMapper in one project. From a coding point of view it is not that hard to implement this feature.  
I need this feature because point cloud from 1/8 image scale adds a lot of noise to the point cloud. And the 1, 1/2 image scale creates some holes in the asphalt area. This is very important for TIN generation from point cloud
