      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Add Detail with Greebles!

6 posts in this topic

At first I thought that greebles were just textures, but I was told that they affect geometry as well. The star wars ship was a basic model. All of the detail (extrusions) were the results of greebles. Greebles are basically just collections of textures indeed, but the term includes displacement maps as well (which affect the geometry). If that is what detail textures are, then I guess they are the same thing. 

 

I am going to try to make an example of how greebles can be used and post it here:

I'd understand greebles to be simply the "random" crap that you add to models to get things interesting.  This wouldn't be like "wrinkles" on a face because that is necessary for a model, but for example the sci-fi stuff, but it could be things like pipes, cogs, resistors, that kind of thing, that while are needed for interest, aren't necessary to directly show that a ship is a ship, whereas you "need" wrinkles on a face to show age, hence the difference.  I guess it could also apply to organic models, but from what I've seen, the term is mostly used in sci-fi art.

 

As far as the creation, I think it could be either as modeled geometry(either sitting on to of, or part of, or displaced from the original model), or bump/normal mapped onto it.  The method actually used would likely depend on the where the final product is ending up.  Also, modelling it could be used to create/bake a normal map for it, but in any case, I think it ALL counts as "greebles".

Ah, that clears it up kburkhart84. I am going to try to make some cool stuff with this technique. I have to get the displacement map thing working right though.

I made a blog post related to this idea a while back (referencing the Super Star Destroyer, too!):

Essentially, I thought western designers over-greeble spaceships so that they tend to make monolithic but boring designs.

 

Hehe. I am surely going to read this when I get the chance. I might even attempt to model a few of those spaceships there.
