Object in Objects ?

Hey

Iam pretty new to Blender and i have a quick Question.

i modeled a small house with: roof, walls, windows and a door.
for each part i created a new plane in editing mode, so its actually 1 big onject. i can use strg + L so select one of them.

My problem is now that i dont know if its possible to give all these object their own texture or if i can only give everything the same texture ?

General Question:
Is it better to make real new Objects for every part of a house or should i do it like i did before ?

Is it better to make real new Objects for every part of a house
Is the house you live in one single object ? My house isn’t so I assume your’s isn’t either. If it’s not in the real world why make it one in your virtual world.

as i say on most of my posts. it depends on the end use! lol!

if your just rendering a scene, how you get the end result does not matter.

yes, you can texture the parts individually, you can create new materials. L select linked on each subcomponent of the mesh, and assign the selected part of the mesh to that new material. OR you can UV map and generate a template to paint on in photoshop/gimp.
