Is Ambient Occlusion possible for Android in Unreal Engine 5?

[PieBaron (NNenov)]

Ello, I’ve spent most of my day trying to get AO working in my project, but I cant get it working, I followed different instructions for setting up AO for mobile (enabling mobile HDR, enabling AO, trying all the post process settings) but the AO pass is always just plain white.

You are still limited by the performance of the device so you need to be careful with how many features you use. The downside is that you will only be able to target the very newest Android devices. Also, you will need to compile the engine from source and, I believe, there is only support for th…

I hope this can help!
