mahdi71, Unreal 4 Lightning system is stronger than Unity. We tested Unity with different systems for previous projects and comparatively to Unreal 4, Unity pales.
Now, I disagree with C3 having 3D. If its done externally like what can be found for C2 then why not, but I think C3 should continue focusing on 2D instead.
After all not many users will be able to build 3D games.
which version of unity you test on?
look at "desert of kharak" night maps then you get why unity have better lighting system
and what settings and shaders did you use ?
can i see some pictures of unity vs unreal with same assets and same shaders lighting and settings?
because unreal use so much shaders on default but in unity you must spend some time for shaders and shadows and ...
and if construct 3 had 3D then more users will come
