How can I achieve such a high level of image quality?
It’s going have to be a combination of a number of techniques including:
- Level of detail logic where you are only rendering the objects that are you closest to in high detail. Objects far away would be lower in detail. Both in models and materials.
- Optimisation of models poly count where possible
- Reducing overdraw
- Reducing draw calls through batching, instancing and material optimisation
- Using lightmaps in combination with dynamic lighting
There’s probably more and @Leonidas may be able to offer more insight. His tools also help with a lot of this too.
