Can Unity do this? [Realtime Archviz]

Win

Hello fellow graphics enthusiasts,
I am currently creating a realtime archviz walkthrough with Unity and I've come across this website: https://ue4arch.com/
Youtube: https://www.youtube.com/watch?v=Gah8sHA1r_8 (UE4Arch - Lake House Real-time Archviz)

Now I'd like to ask you to take a look at this and tell me wether this level of visual quality can be achieved using Unity3D. Because if that is not the case I am currently wasting my time in a major way trying to create these visuals in Unity.

If it's not possible, I would be switching to UE4.

Thank you!

Win

Yes. The question is, are you capable? The tools are there, just look around on the Unity site for archviz examples.

Hi thanks for the answer, can you give me some resources that teach advanced lighting in unity?

Eric Chadwick

Can you show me what you've searched so far?

I cant really find any advanced tutorials on lighting though...

Hey man!

For just advanced lighting you can get most of the info from the documentation, YouTube and papers people have written about it. But let me be straight. When you then have finally nailed the lighting. All you will have at that point is a clean GI and some baked lights & probes. This is not enough for the whole scene to pop like your example.

To get something like your example you will need:
-Optimized 3D assets. All of which will need good poly count, texturing and shading.
-Well optimized scene model. One with proper texel density and no/little light bleeding.
-Image effects for the camera. Used to properly tone-map, create transitions from indoor to outdoor and real-time reflections that don't break the frame rate.

So in short, yes it is possible but it is not just a tutorial you can check to pull it off.

Sources I recommend:
Unity lighting introduction, you will need to check this whole document.

Thank you for your reply, I have looked into your links and it certainly has helped me. However I don't know what you mean with texel density in relation to the scene model. Do you mean that all UV shells of the level should be the same size relative to the geometry?
