This lesson gives a sample lesson plan for involving the V-Ray Fur module into a lecture.
- Explain the concept of Dynamic Geometry
- Dynamic geometry is only kept in the RAM when it is being rendered.
- If you are rendering with the Bucket Image sampler only the parts of the geometry currently being rendered by the buckets need to be in the memory
- V-Ray Fur takes advantage of the Dynamic Geometry approach by generating only the strands that are currently being rendered
- Next, review some existing renders or images that show examples of possible usages of V-Ray fur, such as:
- Fabric such as fleece, stuffed animals etc.
- Cover the settings of the V-Ray Fur
- Different ways to control the density of the fur – Per area vs Per face
- Length, Gravity, Bend and Knots and how they relate to each other
- Thickness and Taper and how they relate to each other
- Adding variations
- Shading the fur is also covered in this lesson. The main nodes used are:
- VRayHairInfoTex – a utility node that allows us to control the shading along the fur strand or to add randomization based on the strand index
- VRayHairMaterial – generally used to render hair, it is suitable for grass because it has both a translucency layer and a specular layer
- In this cycle, you can use the provided scene and handout to demonstrate how to set up the V-Ray Fur
- In this cycle, you are going to let your students experiment with the provided scenes. You may want to give them the provided handouts to use as a guideline
