You can write your topic however you want, but you need to answer these questions:
**What do you want to achieve? I want to know what makes a roblox game look photo realistic is it the lighting the pbr textures realistic builds or all of them?
What is the issue? i’m unsure on what makes a game look photo realistic
What solutions have you thought of so far? I have searched for this question on google but no results
To achieve the highest level of photorealism possible on Roblox you would need a combination of high detail, PBR textured assets, adjustments to the lighting settings of Roblox, and obviously good-looking meshes. You pretty much answered this yourself. The hard part is keeping a game performance-friendly as Roblox’s engine isn’t the best for high detail builds. Anyways if you have any other questions, feel free to ask.
