Maya 2020 fundamentals - modelling the real world
Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

Normal map texture, with some reflection?

So, lets say I want to normal map a building that has windows, once it is normal mapped, and I go to texture it, how do you keep the window part of the normal map reflective, while the building is not? Something with the alpha channel?....user added image

Thanks!

Thanks. And is it possible to normal map windows and building, into a simple cube mesh? I tried but it didn't work.. Probably need verts around where the windows are, but then that kind of defeats the purpose...

It should be, make sure the meshes are in the same space and that the simple mesh is slightly bigger..............dave

What kind of settings should I be using that would be different than character normal mapping? Besides objectspace. Should I be using geometry or surface normals in the advanced setting?

I've achieved good results with characters, just with maya baking. I don't know what it is that I need to do differently though.

Some time maya will return bad normal maps that's why I have stopped using it for them, you will not get any real depth with normal maps as you can see on the top part of the right box...............dave

Are you saying you can't get much depth from maya's normal mapping, or just normal mapping in general?

You will not get true depth but a affect of depth so you need to think were to use a normal map your window should be OK also lighting and texture plays a part in how they look................dave

Yeah, not sure what I'm doing wrong... Do I need more verts? Can it not just be a plain box for the low poly?

I would say mainly normal maps with texture with some extra poly meshes here and there to add some depth.............dave

Edit: do try xnormal it is easy to use
