[No 3D objects were rendered? There is a compatibility issue with QGIS 3D view...] #339

Hello,

Issue or? in an existing project.

Error : No 3D objects were rendered? There is a compatibility issue with QGIS 3D view. You need to close QGIS 3D view(s) and restart QGIS to use this preview.

but I don't and never defined/used QGIS 3D views in this project.

It was running fine a couple of days...

The Qgis2threejs re-installation doesn't solved the issue.

A lot of WebGL/Java Errors see screenshot attached.

I've had problems, too, and get the type of errors you show when loading GeoTIFF from USGS (United States Geological Survey). I went a step further and proceeded with an export which occurred. Then I submitted two of the image files, i.e. test_export_gLTF.gltf, generated from the Qgis2Three plugin to Don McCurdy's site at https://gltf-viewer.donmccurdy.com/ and got these type of errors/warnings:

at https://gltf-viewer.donmccurdy.com/ attempt to view:

/home/jlpoole/qgis/3DExport_Apr_16_2024/test_export_gLTF.gltf

resulted in a black screen

When I clicked the errors icon at bottom left, this page:

Unfortunately, I do not possess enough knowledge at this time about gLTF to know if these are fatal errors or not. I am troubled by the "IMAGE_NPOT_DIMENSIONS" errors which may be caused by my selecting a smaller area to export which perhaps is suppose to have a "power-of-two" dimension?
