I’m investigating the feasibility of developing a 3D room and home design tool with realistic rendering and interactive features. The goal is to allow users to place objects and modify textures in real-time, maintaining high visual fidelity. Can Unity’s rendering pipelines (URP or HDRP) handle the dynamic lighting and object manipulation necessary for this, while ensuring realistic rendering? Insights from anyone with experience in similar projects would be greatly appreciated.
I haven’t worked on a project like this before but I think HDRP would probably be good enough. Not sure if you’d get something as good as the IKEA demo above though. Kind of depends on the platform too, if you’re looking at mobile then HDRP might be a bit much for it. If it’s only for PC and realistic graphics are a high priority then it might be worth comparing it with Unreal. I think there could also be some restrictions with game engines and non-game content. I’m sure Unity has some limits on using it for a CAD application for example.
The problem is if you want dynamic bounce lighting, that would require SSGI of some form.
Either kronnects solution or the opensource solution posted here. Note SSGI can be heavy on mobile devices, just depends.
Couple this with APV if you want time of day and it should look good. But much if it is knowing how to render things in a game, good light settings and such.
