Best way to assign small textures as a part of a big plane

Support Materials and Textures

Hi everybody and greets from Germany,

I am working now with Blender for almost two months and as an exercise I create a spaceship in an airport. This is my picture so far.

No I would like to add more boundary lines on the floor like road markings for the spaceship. What is the best way to do this? My floor is one big plane with a smaller rectangle in it for the yellow/black-line. But I cannot imagine that I have to subdivide my floor into many sub-rectangles so that I can place my boundary lines on it!?

So is there a way to place many small textures (like boundary lines) on the floor which only consists of one big rectangle or do I have to create one big texture including the whole boundary-map with alpha-channel?

Thanks for any suggestions and comments!

now, im by no means an expert, but i would guess you could try using empties and mapping the textures to there and seting them where u want them.

The technique is known as “Decaling” and there is a very good video tutorial explaining it below.

Besides DECALING you can simply use a UV texture.

Unwrap your rectangle with the UV Editor. Export that with the UVLayoutExport script to your favourite Image Manipulation Programm and start drawing a texture of the floor including the markings.
Save that image in a format understood by blender (png, tga etc…) and add that to a texture channel of the floor. Don’t forget to turn on UV Coordinates for the Texturemapping and press Col and you should be all set.

thanks for the responses. I wil try to do it with decaling.
