V-Ray Blend and Bump Materials

This lesson gives a sample lesson plan for involving the V-Ray Blend and Bump Materials module into a lecture.

Discuss overall concept of the V-Ray Blend Material and how advantageous it can be to mixed multiple materials
- Layered material – the rendering is optimized. V-Ray first calculates the compound effect of all materials and then does the raytracing.
- Base vs. Coat
- Masks and how to control the blending
Next, review some existing renders or images that show examples of blend materials
- Sudden blends
- Gradual blends
Some suggested talking points are:
- Making a choice between using a Blend material vs. modeling a separate object and assigning it its own material
- Planning your layers before starting to build the material
- Nesting Blend materials
One major point is that the V-Ray Blend Material doesn’t have a Bump map slot. To go around that issue we can use the V-Ray Bump Material
Let the learners know this is an intro to the attributes and they will have a chance to see them at work during the Demo and the Activity stages of the Learning Cycle.
You will find a lot of material to use in the academic portal as well as cutting and pasting any additional information from the relevant documentation pages.

In this cycle, you can use the provided scene and handout to demonstrate how to set up the V-Ray Blend material and how to add bump mapping to it using the V-Ray Bump Material

In this cycle, you are going to let your students experiment with the provided scene. You may want to give them the provided handouts to use as a guideline
