There are a lot of technical reasons why this may not be possible. For example, modern real-time lighting often uses precomputed data such as lightmaps to speed up/avoid real time calculations. For static geometry and lighting much of the work can be done 'offline' before runtime however it is not unheard of for this offline process to take hours (e.g. computing high resolution lightmaps for large environments).
- JonAtkinson 7y agoThere has been huge advances in this area recently. Real-time ray-tracing and lighting is Nvidia’s primary marketing push right now with their RTX cards. Unity/Unreal/Blender can all produce very high fidelity real time lighting while editing. It’s great technology.
