How can I do?

Hello Nicola,

Can you please confirm, if the issue is still there after the GPU driver update to the latest compatible version?

And whether the crash doesn't occur, if only CPU is used for the processing (GPU disabled, before building the dense point cloud)?

[nicola.coscini]

I have two GPUs:
Intel UHD Graphics and Quadro P620.
With Intel Disabled the proces is ok.

Hello Nicola,

If you want to use integrated Intel UHD graphics for the processing, please check Intel web-site for the latest compatible driver version.
According to log it is 27.20.100.9664, but for Windows 10, for example, the newer version 30.0.101.1191 is available:

Hi,

FYI - I'm hitting the same issue with 1.8.2 (Standard) and latest Intel UHD drivers.
Disabling iGPU works for now, but reduces performance to some degree.

I'll try to isolate the offending part of the dataset so you can pinpoint the issue.

Hello lobradov,

Which Intel UHD model do you have available in your system and which driver version is installed now?
