Why is the volume fog formed by texture projection ineffective in the light function of UE5.5.4 ver,
Why does the use of colored texture maps for light function not work for volume fog, and even the shape of the projected texture map for volume fog is lost? If there are problems with upgraded new features, it’s not a big deal. Why do some old features often fail, wasting users a lot of time looking for the cause? Why do these low-level errors always occur? It’s really infuriating,，，
I have asked users of versions before 5.5.4, and they are all correct，it is ridiculous that only 5.5.4 has this bug. How can I download the patch for 5.5.3 and why there are no detailed options? Because my project files have been upgraded to version 5.5 and I cannot use version 5.4 anymore
That sounds incredibly frustrating, and you’re right to be annoyed when features don’t work as expected, wasting your time.
The issue with colored light function textures not affecting volumetric fog (and losing shape detail within it) is usually a performance-related limitation. The calculations for volumetric effects often simplify the incoming light data, skipping complex texture lookups within the volume itself.
Regressions (old features breaking) can happen in complex software when changes elsewhere inadvertently impact them. It’s a common, though aggravating, part of ongoing development. Make sure to report it officially if you haven’t already.
