What is the bug or the crash?
Hello,
When creating VPC with point cloud available in my personnal hard drive, the processing is OK.
But when I create a VPC with the processing tool, using copc.laz files available on cloud storage (https/uri), the processing stop with error
For me, it's really powerfull to create VPC from cloud stored data
For responsible digital : datas are stored one time, and can be used worldwide (without need to upload all the datas before using them)
Steps to reproduce the issue
-
Import copc.laz files from https/uri

Use the processing tool to create VPC

I choose the 2 pointcloud entities (https://...), and I write the VPC file on my local harddrive
I explicitely choose the *.vpc file format
