Hi everyone,
I’m working on a project where I want to simulate a heat map based on sunlight. My goal is to use that data to drive a simulation of temperature changes. I understand there are various ways to create heat map visualizations, but for this specific project, it’s important that I use actual light information. This is essential for the simulation to be physically plausible and as I see it, Lumen already has that data.
I’m aware that Lumen is a complex system, and directly accessing this data might not be straightforward.
How can I access the Lumen global illumination data for individual surfaces in real-time?
Are there specific functions or classes within Unreal Engine that provide access to Lumen’s lighting data?
Any guidance, suggestions, or pointers to relevant documentation would be greatly appreciated.
Thanks in advance for your time and help!
