Hey guys, what exactly is Default RHI in project settings? I have scoured the internet for this answer but didn’t find it. I understand what RHI stands for but how does it determine the output render quality especially with raytracing? UE4 documentation has a page on RHI but its just coding commands, nothing to explain what it does and how it would “visually” change your project if you select the default options.
The reason I ask is because I want to use a tool (Animated GIF Importer from the marketplace) which will crash UE4 if the default RHI is set to DirectX 12 (DirectX 12 I am assuming makes things look prettier). However if I set the default RHI to Default, the tool works flawlessly. I don’t mind this but just don’t know what I am losing by setting it to Default instead of DirectX12 ? Visually it looks like some raytracing disappears if I do that and some shadows become steppy and low res looking.
Can provide comparison images if you guys want.
