I want to model for games.I'm using Unreal Engine for developing a game.And I have a few questions about modelling smooth looking models with low poly:
How many triangles supposed to be in a basic decorative model for a game which has a large map. Imagine You are modelling a mug and its just a decorative on the table and ı want to be my games graphics look nice I tried to model a cup and it took 2k-5k triangles is this too much? Subdivision Surface Modifier makes poly count very high.But without it models looks angular what am I supposed to do?
I wanted to make poly count lower and I tried to bake normals with a very low poly and high poly meshes.Low poly and high poly meshes was really different looking.High poly mesh was modified with Subdivision Surface Modifier twice but low poly was unmodified so when I tried to use this normal map on my low poly mesh it was looking weird(look photos for what ı mean)
Unreal Engine has an LOD system and when I try to make different LODs for my model with decimate modifier what I suppose to do about normal maps?Do I have to bake normal maps for every one of them.And its not just normal maps what about uv's and textures.
