5/53

Reference material for Characters

- Good reference drawn or pictures matching up. - Preferably t-pose- A reference is a guide for you when you model.

T-poseGood reference material for proportion


6/53

Research material for Characters- Always research HOW to build it before you start:- Look for topology- Examples of techniques- Tutorials that are similar to prepair with if you feel it is necessary

- Before you start ask yourself: Do I know how to model this object,have I any prior experience with a model like this?- If no, how can I get some experience before I start modeling thistype of model. (from modeling to rendering)?- Never start with your "real" project before you have tried a tutorialor a dummy project in a smaller scale of a modelingproject

resemblingyours.

- Finally, If you can't find the material you need for your project,change the project to fit the material you did find.


7/53

Topology for Characters

- Quads preferably- Smooth- Start with a lowpoly then gohighres.


8/53


- Follow the flow of themuscles for good deformation.


9/53


- Build edge loops following the muscle structure for good smoothing and animation

22/53

Box modeling the torso- Prepair to extrude shoulder by inserting extra edge loop och placing the vertexes.- Pick the faces and extrude it in X-axis first, place the vertex point after the refrence, and extrude down in theY-axis.
