Character Creator 3 and converting character to 'Game Base'

Character Creator 3

When you open Character Creator 3 Pipeline there is a large button on the right-side Attribute menu that says, “Convert to Game Base.”

This simple button is a bit misleading though. While it does convert the character to Reallusion’s idea of a game base, it also opens a world of creative options for game developers who aren’t character modelers or animators.

In fact, it opens your game development up to the entire iClone-Character Creator universe complete with drag and drop animation, a huge user-driven marketplace along with professionally created assets by some of the best 3D modelers in the game today. And a lot of drag and drop animations from motion captured to keyframe.

Earlier you might have noticed I said “Reallusion’s idea” of a game base character and I did so for a reason and that is to temper one’s expectations with reality. We all have different ideas of what a game character should be and a lot of us have unrealistic expectations in that area.

To help alleviate some of this Reallusion listened to its user community as it so often does and brought together the attributes that seemed most important to game dev users (from Reallusion website):

CC3 is not a magic pill or an easy button but it’s close.

By just pressing some buttons and making some choices you can generate game-ready characters in different LODs from existing, modified or stock meshes.

If you are a code-hound and not a 3D modeler, particularly if a tight budget stalls your project and prevents you from hiring one, Character Creator 3 gives you the opportunity to move forward.

At the very least, CC3 provides game-ready characters for placeholders to continue development or by using all of its features to create your own custom characters and save dev dollars. I’ve never known a game dev that didn’t want to save dollars.

Game Character Base is just one of the many new features in the standalone Character Creator 3 Pipeline application. Just this feature makes CC3 a powerful tool for both veteran, intermediate and novice users wanting to be more creative and less technical while wanting to include NPCs in singles, groups, and crowds along with the storyline characters.
