"Photo-realistic" quality rendering between Unity and Unreal 4

Here you go,
Both are zero roughness


Edit :
Had to shift the roughness a bit in unity to at least get the same looks



also no sure about the color differences

 

Alright. Some screens.

Keep in mind that there is no baked light, and the whole scene was originally very carefully created to show off unity engine, so most of the objects do not cast shadows, lights are too dark, and blue tint is from sky light that is bleeding through non-shadow-casting level geometry.

 

Here's what happens if I shut down the skylight.

 

I'll try lightmap baking later and see if I can come up with better unity->ue4 lightmap brightness mapping. By default the scene is very dark and requires auto exposure to bring it up from below 1.0 brightness value.

The scene is from unity lab demo.

Missing shadows are a result of oringal geometry flags. For example, pillows do not cast shadows in original scene, and spot light above the couch (there's two of them) also isn't casting shadows, at all).

I gotta say in case of UE4, huge visual impact comes from reflective surfaces.

I'll also finish baking unity scene later. Had to wipe GiCache to free up some hdd space...

 

What the hell is up with the lighting in those screens? Talk about unflattering to the textures! Needs a bit o' messing aboot..

 

The lighting is copied verbatim from unity scene. Ranges, angles, light positions, colors and all.
The thing is, Ue4 uses physical model (lights are specified in lumens or something), and in Unity they're 1.0..10 values.
Also, that's without any baked shadows.
Also, there's skylight lighting up the scene, because none of the environmental meshes cast shadows. That's also original settings from the unity scene, copied verbatim.

Wanna know what that "two glowing columns near doors" look like in unity before lighting is baked?

I'll mess with it a bit more later, but not today.

 

Ouch, I appreciate all the work you did.. Thanks for posting it, could you maybe zip the scene and stick it somewhere? I got to admit, all it shows at the moment is how not to do a scene in two engines.

 

I think I'll just PM you on that matter (I take it you'd be interested to see what you can do with it, right? In UE4) either later today or tomorrow. Need to take a break at the moment.

THe last thing I expected to do while fixing that level transfer tool was writing custom json serializer in C#.
