...just finished doing that...it's detail doesn't have much improvement, but the frame rates are higher

The easiest way to add some detail to your terrain is to use a detailmap.
Just create a small (f.e. 128*128) tileable greyscale texture and add it as the second skin to the hmp file.
This page is in german but on top are two examples for detailmaps:

It will already look much better, though a multitextureshader would be even cooler

Oh, I cant really read simplified Chinese,
but from what i can read is:

Blood, magic, type of magic, weapon

yes, I had a hard time translating it to Chinese too. NHA uses ilf and nfs format for spells and items, but it didn't support Chinese so I converted them to txt format

with detailmap:

I don´t see a detailmap? o.O

how do you the shadow effect ?

It needs less uniformity. Try varying the buildings. Be careful of using the same model twice. I mean, some famous games like World of Warcraft do this, (presumably to save time, money, and memory) but it can be really bad to do it too much. Almost every town in WoW has the same looking inn for example, but Blizzard makes up for it by making diverse and expansive zones that players run around and fight in. They barely notice that Goldshire and Darkshire and Lakeshire (Shire? ) and all these other towns have the same buildings. I guess what I'm trying to say is, go for variety. If you can pull off reusing a model, great, but be subtle when you do so.
