PhotoScan 2.0.0

I created "Multi-camera system" by a folder with 3 bands/sub-folders.
Everything works fine, I can even export ortomosaic for each band using raster calculator and adjusting palette.
When I try to export dense point cloud, I get this result:


0.699327  5.652912  0.253759  39  39  39
0.698156  5.652623  0.253544  56  56  56
0.699830  5.651976  0.253567  43  43  43
0.698863  5.652648  0.253539  58  58  58
0.699805  5.652681  0.253532  44  44  44
0.698644  5.652169  0.253564  52  52  52

Only the master channel colors are reported.
I tried .las .ply and .txt format.

UPDATE
nor mulipage or multichannel tiff ensure three different channels in point cloud export

Hello sam.b,

Can you please make sure that "enable transform" option is disabled in the Raster Calculator dialog (on the Transform tab) and that "Convert colors to 8-bit RGB" option in Export Points dialog is also disabled? Whith both features disabled you should be able to export the point cloud to XYZ.TXT and PLY formats with the colors for all bands. As for the LAS export, due to the format specifics it would save RGB+NIR bands only.
Best regards,

Hello Alexey Pasumansky,
I have disabled both options but nothing has changed in XYZ.txt.
I noticed that even if you uncheck "Enable transform" and apply, after closing the window and reopening it, "Enable transform" is checked.

Hello sam.b,

Can you please send an example of the such project to support@agisoft.com and also specify the build number of 2.0.0 version that you are using?
It would be sufficient to have only the part of the point cloud (dense cloud) in the project copy, but use Compact Point Cloud option to reduce the project size.

hello Alexey Pasumansky,

I sent the point cloud sample from this account e-mail with this topic as object.
I used Metashape Professional 2.0.0 build 15359

Thank you for your kind help
