I’m starting to learn unreal engine and i’m having a problem, i tested unreal 4.27.2 with path tracing and worked fine, but with unreal engine 5 i cannot use path tracing, i’ve changed every setting needed to use path tracing but the button to shwitch to path tracing is not there. I don’t konw what else can i do, i don’t konw if they change something that disable path tracing for my GPU (GTX 1070), or if it’s a bug or if i’m doing something wrong. If someone can point me to the righ direction i would appreciate.
(Sorry for any english mistake, english is not my main language.)
Unfortunately since the Preview version of UE5, Epic has disabled emulated raytracing console variable which allowed Pascal GPUs to use hardware ray tracing. Fortunately, there is a way to work around this, you have to recompile the engine from source with a slight change to one of its files, the steps are described in this thread reply: Cant enable raytracing in ue5 (gtx 1060) - #24 by Julian_Stys
Hey there, I see no one really answered your question. Someone did pop a link to a previous post below your comment but I too have the same issue, does anyone have an answer to this? Just like yourself everything is switched on for me but alas, under Lit mode there is no Path Tracer Oh I am using 2080 GFX so should work.
Edit: I can confirm it is working for me in UE5.0.3 but for 5.1.0, it’s definitely not there.
I had the same problem with 4070ti in UE4.27 and UE5.1. Then I created a new project and enabled raytracing when setting the project defaults, and it worked.
Oh I am using 2080 GFX so should work.
