Is there a way to Rotate HDR Images within SkyLight or PostProcessVolume? or atleast to give it an offset??
i need an rotatable background (sky sphere) that emits light out of an material to an mesh.
i want to achieve some thing like this, by only rotating the skysphere.
do i really need a hdr image for emitting light? or can i activate something in the material to do this??
Hi Peter -
We actually have this setup in the Starter Content’s Advanced Lighting Map. You have to build a blueprint which adjusts the skysphere to use a particular cube map then updates a movable skylight also in the BP (if you want updates at runtime). I’ve removed just this section of the Starter Content for you below.
Thank You

awesome
thx
i will build this into my project this evening and answer later again…
i didnt know that i can control the hdr image with the light source…
Took me longer to interact you logic, i didnt got the light information from the sky sphere/box. this was because by sky object was much smaller than your…
i just had to scale it up and it was working like a charm…
thanks again…
yes i am ok with this…
Just want to add a note here.
I wanted to rotate the HDRI at run-time so I tried as suggested above. So I tried simply adding a float value to the HDRI rotation variable. However I noticed nothing was happening. I then realised that a value of 1 is too high, the HDRI was rotating so fast it looked as if it was standing still. Only add a value of 0.0005 or so. Here is an example of what I added to make it work. Also make sure to recapture the scene at the end.
Just wanted to point this out, simple thing but did confuse me a bit.
