Hi I put this comparison betwen the game model and the same model and textures loaded in rendering software as you see the normal map is barely visible ingame why?

I don't know if this is related, but I've always had this issue where strong changes on the normal map do not really render in the game. For example if you bake normals for a model with only one smoothing group, it doesn't look right in the game even though in an outside renderer, it will look fine. In-game it looks more like the smoothed model without normal maps. So I have been using smoothing groups + normal maps. I don't know why this happens, but it seems like it's sort of the same issue...

so what I should do ?

I don't know, use parallax mapping?

?
