@chrisradsby found an issue with the demo maps (which should be reproducible elsewhere) with planar reflections being completely missing when night time and even with the Moon up. Basically no stars, no Moon or clouds can be seen. This happens because of an error in the main raymarch material which negates the transmission (blend mode: alpha composite) resulting in dark areas underneath, so the planar reflections are translating this to an absence of reflection. If you uncheck Visible at BP_CloudscapeViewer you will see the reflections back. This issue also impacts the light intensities at night time, meaning that if you have created a level showing night time, you will see all the light types probably too strong and you will need to adjust that aswel. I will leave a video posted here and at the Discord channel showing how is the impact on the lighting and how you can change the cloudscape parameters to compensate aswel. If you only created day time levels, you won’t be affected.
With that said we are about to release another update (fix) 1.2b in the next days after we finish the tests for all scenarios of Sun and Moon position through the Sky!
