Lesson Introduction – Orientation • This presentation will take you through setting up textures for a basic material • This information centers around the use of textures with VRay. Mtl • The lesson topic is approximately 20 minutes in length • Presentation covers all 3 Learning Cycles for the Lesson Topic – Lecture, Demonstration, and Activity

 Lesson Topic: V-Ray Material Textures • Objective – We will use several textures

Lesson Topic: V-Ray Material Textures • Objective – We will use several textures to create and alter a material in the scene • Develop the look for the owl statue • Use various textures to create different looks • Outcome – You will understand how to work with textures in a VRay. Mtl to create a specific look

 Lecture: Terminology • Here’s some terms to be aware of when thinking about

Lecture: Terminology • Here’s some terms to be aware of when thinking about textures – Bitmap – An image file containing colors and patterns – Procedural Texture – Color pattern generated by equations within the application itself, not pre-made pictures; checker and fractal are examples of procedural textures

 Lecture: Textures in the Real World • In life, “texture” refers to how

Lecture: Textures in the Real World • In life, “texture” refers to how something feels to the touch • In V-Ray, a “texture” is simply a pattern of colors that is applied to attributes

 Lesson Topic: V-Ray Material Textures • Textures Overview • Can be used to

Lesson Topic: V-Ray Material Textures • Textures Overview • Can be used to define just about any V-Ray parameter set by color or number • Mix of textures needed for realism

 Lesson Topic: V-Ray Material Textures • Texture as Diffuse Color • Sets a

Lesson Topic: V-Ray Material Textures • Texture as Diffuse Color • Sets a pattern of colors as the object’s main color when it is in light

 Lesson Topic: V-Ray Material Textures • Texture as Reflection Color • Sets coloring/amount

Lesson Topic: V-Ray Material Textures • Texture as Reflection Color • Sets coloring/amount of reflectivity across an object

 Lesson Topic: V-Ray Material Textures • Texture as Bump Map • Grayscale values

Lesson Topic: V-Ray Material Textures • Texture as Bump Map • Grayscale values make surface appear to push in or out

 Lesson Topic: V-Ray Material Textures • Texture Filter • Sharpens or blurs the

Lesson Topic: V-Ray Material Textures • Texture Filter • Sharpens or blurs the texture • Higher value = more blurry Filter = 0. 01 Filter = 5. 00

 Lecture Conclusion: V-Ray Material Textures • Texture – Pattern that defines a parameter

Lecture Conclusion: V-Ray Material Textures • Texture – Pattern that defines a parameter • Procedural Texture – Created with an equation • Filter – Sharpens or blurs the texture

 Time to see it work! • Demonstration Cycle! • Watch while I demonstrate

Time to see it work! • Demonstration Cycle! • Watch while I demonstrate how to set up textures for a basic VRay. Mtl material

 Time to do it yourself! • Activity Cycle! • Now it’s your turn!!

Time to do it yourself! • Activity Cycle! • Now it’s your turn!! • Use the provided scene file to set up a textured material for the owl • The next slide provides some specific values I used for your reference

 Dialing in the right values • Wood_05_Spec. jpg – Reflection Color • Wood_05_Bump.

Dialing in the right values • Wood_05_Spec. jpg – Reflection Color • Wood_05_Bump. jpg – Bump Map • Filter – 0. 1
