This lesson gives a basic sample lesson plan structure for involving the V-Ray Frame Buffer module into a lecture.
This lesson gives a foundation to help new V-Ray users in understanding the options of the V-Ray Frame Buffer
- Since this lesson is introductory and there isn’t much theory, the lecture will be much shorter and more time will be spent showing the options of the V-Ray Frame Buffer
- You may spend some time explaining the difference when applying color corrections to e 8bit image vs a 32bit floating point image.
- Sometime maybe spent explaining Look Up Tables and when and how they are used
- In this cycle, you are going to go over the options of the V-Ray Frame Buffer in 3ds Max.
- Note that to demonstrate the ability of the VFB to hold multiple render elements, we have added some in advance. You could give a basic definition of render elements and move on since they will be discussed in a different lesson.
- When showing the Save options note that you can choose how the render elements are saved – either into separate files or into a single file (.EXR or .vrimg).
- Render region and Track mouse while rendering are both ways of giving V-Ray priority on what to render. This can be useful when working on shaders for example.
- Most of the time should be spent on Color Corrections
- Note that the image is in 32bit floating point format which allows for a greater control
- Note that each type of corrections can be saved, loaded or reset. Additionally, you can save all color corrections into either a V-Ray specific format or into a LUT
- When working with the Background Image feature note that if we want to use the image as an overlay it should have a proper alpha channel
- The History window of the VFB is another important part as it allows us to store multiple images in a .vrimg format and do A/B comparison. This is useful in comparing shaders or different lighting setups. You can also demonstrate that the A/B comparison works on render elements.
- In this cycle, you will let the students use the provided scene and handout and try the different V-Ray Frame Buffer options on their own
- You may create different scenes and challenges that cover the same basic information, presented in the Lecture and Demo.
