Welcome. In this tutorial I want to let you have a look into the way I textured the scene below.
I wish to concentrate on two techniques that will serve you well on plenty of different occasions.
This image was created using 3D Total's TotalTextures-CD's - a quality collection of high-resolution texture maps.

Please chose the topic you would like to deal with below :

on the left you can find out how realistic ageing plaster can be realised, while on the right I am presenting you a way of combining texture maps to create marvellous aged surfaces using a technique called alpha blending - something that should be known to everyone.
