HiDPI Compositing BUG. – reflection cubes not working with HiDPI Compositing

10/4 UPDATE: < updated title to reflect actual problem >

Verge3d 3.8 for blender osx.

Problem: When using the OnloadScene to load a new verge 3.8 scene…if the second scene has a lightprobe the reflection cubes do not work.

Cause: 3.8 GLTF exporter not working properly

Validation:
Reinstalled version V3D 3.71 and created a main loader scene in 3.71 and then loaded a 3.8 GLTF with reflection cubes. Result reflections work properly.

Reinstalled version V3d 3.8 and exported the main loader used previously. Result reflection cubes do not work properly.

NOTE: the below reproduction steps are based on the actual applications shipped with Version 3.8. The Load-Unload scene uses older GLTFs not GLTFs created with Version 3.8. This caused us confusion but resulted in the ability to isolate the problem.

Reproducible / Validation Steps.
Step 1. Create a v3d 3.8 application

Step 2: create two gltf files. the first as the main scene and the second as a scene to be loaded. In the scene to be loaded it needs to have some reflective material and a reflection cube map.
Update 10/4 < NOTE MODIFYING TITLE TO REFLECT ISSUE AS WE GET CLOSER TO NARROWING IT DOWN >
If both scenes are created using 3.8 for blender the reflection cube map will not be processed when loading the second scene.

If the initial scene is created exported using V3D ver 3.71 and the second scene was created in V3.8…the reflection cube maps work.

As a double test… I used the Load-Unload demo that has a 3.8 V3d app build using older GLTF files. And then loaded the second scene with the reflection cube map and reflective materials and loaded that in with the replace scene…and it too failed to calculate the reflection cube maps.
