Zachary, I think there are a lot of bugs in the latest release
What I have found is if you change processing options (and option turns red as you pointed out), the errors will appear when trying to edit, view etc
Changing the processing options to the original settings that you proccessed (turning option green) will eliminate errors
I found a round about way of making the texture work after the [Error]: Error e9036: GDAL error <4>, thankfully I didnt have to reprocess out a HQ 4km mesh again. This involved moving texture file from 3d_mesh folder to the project_data folder and adding the suffix ‘1_1’
I hope pix4D can get to the bottom of this in the new release, as these bugs have just appeared.
I migrated a number of projects to the new version to experiment and they all gave up errors depite having no errors in previous releases
