So first off I would like to ask about grainy textures, I am using .dds files with mipmaps and the textures still looks grainy at a distance. I am not sure what is causing this but it seems to be a lighting issue. I also was wondering about exporting more then 1 model at a time to keep there transforms relative to each other the same as it is nearly impossible to align them in game since the edges are planes. currently I am using a technique of having "merge" geometry but it leaves a visible seam.
For the grainy textures, set the material to use anisotropic filtering. Either in the material editor, or via the materials.cs file. Code: useAnisotropic[0] = "1"; As for the models, export at standardized distances. E.g. every 500 meters. That way you could place them in a grid like fashion.
Fixed textures by just replacing them, I fixed the seem by just exporting models with the same origin, should have set to solved a while ago but thanks for trying to help.
