The above image has black applied as a color map. Once the required appearance has been applied, we can decide what the other maps have to do. Example: Applying a picture of wooden planks as a color map onto a 3D cube to model a crate. This map is used to apply either a color, a pattern or an image onto the 3D model. They were done on a demo version of Keyshot, but they do get the message through. Lets briefly look at the different types of maps we can use: Color/diffused, Bump, Normal, Specular and Opacity maps. I’d say that understanding the capability and function of each map is mandatory even before experimenting with them. Why the name maps? Because they “map” the “texture image” onto the 3D surface and let the program know where to apply highlights, shadows, colors etc. So let’s get on-to it then!Īdding texture to 3D objects is achieved through different types of maps. With a few example renders, I’d like to share what I’ve learnt. This week’s article is quite exciting! It has helped me understand the steps needed, but often overlooked, to render objects as close to the real thing as possible. Every object has an inherent texture and this makes it immediately identifiable. That is because of their different textures. Does a metal surface look similar to a rubberized one? Does a piece of glass reflect light the same way a piece of clear plastic does? No, right? (I sure hope you said NO!!).
