Hi all, I am trying to take multiple automated snapshots of mesh assets with different HDRI backdrops in the background. I did not manage to find a way to switch the cubemap of my backdrop actor into a different one in mid-game. Tried both of the available functions shown in the snapshot, but both do nothing at all. The name is printed when I press F so I know that the flow does work. What am I missing here? Is there another function or maybe a re-initialization to be done after switching the asset? Many thanks, Tim ---

I don’t know how you’re doing the HDR, but if you use the UE plugin, you can change it like this: ![322113-screenshot-2.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/0/7/b076bd347e37632589cb36bd7c5303bb58e65b61.jpeg) PS: You didn’t leave any pictures. EDIT: I take that back, it doesn’t work… ---

This forum has always been super weird. I did leave a comment after the questions but it seems to have disappeared… ![322079-hdri-cubemap-bp.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/0/6/7066a501d42997ccb19e35a92f85263e33c4d30e.png) ---

I think the only way you can get it to work is preconfigure a bunch of skies, and spawn them one after another ( destroy the old one ). ---

Thanks, what I did was put a few of them in the world and toggle their “visible” or “hidden in game” depending on the script. just seemed like the wrong way to go about. ---

To anyone encountering this in the future, I have found the solution. When I saw that the same issue arises when rotating the HDRI, I opened up the HDRI BP and looked at the constructor. Apparently, there is an additional “post edit” step needed to be done, see attachment. ![324742-hdri-solution2.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/a/d/4ad0214d24cac73857ae430ec65ff16e68db4fa4.png) ---

Ah, I was missing the `Create Material` node. Thanks! ---

Can you please share your blueprint code here? I’m still not able to change hdri background. It show the error trying to read “hdri variable’s” property and found none.
