VRAY FRAME BUFFER Empty VRAY FRAME BUFFER

Post by render master Tue Mar 17, 2009 4:01 pm

VRAY FRAME BUFFER

Comparison of both Render Frame Buffer

3d Max Default Frame buffer
VRAY FRAME BUFFER Vfb110

The Vray Frame Buffer
VRAY FRAME BUFFER Vfb210

Something you need to know on Frame Buffer.
When you rendered an image, while still on the frame buffer ( both for RFW and VFB) Try the procedures below, and it will give you another image output
1. Choose Customize > Preferences.
2. Turn on Enable Gamma/LUT Correction.
3. Turn on Load Enable State With MAX Files. Try to change the gamma value to 2.2,
then press the duplicate button of your Frame buffer, this will give you another image output.
Try another if you wish. Below are some samples

Gamma at 1.8
VRAY FRAME BUFFER Vfb3-g10

Gamma at .5
VRAY FRAME BUFFER Vfb4-g10

In addition to rendering to the 3ds Max Rendered Frame Window (RFW or VFB), V-Ray allows you to render to a V-Ray specific frame buffer, which has some additional capabilities:

•Allows you to view all render elements in a single window and switch between them easily;

VRAY FRAME BUFFER Vfb5-r10

•Keeps the image in full 32-bit floating-point format;

•Allows you to perform simple color corrections on the rendered image;

VRAY FRAME BUFFER Vfb6-c10

•Allows you to choose the order in which the buckets are rendered.

Parameters

Show last VFB - If you have rendered to the V-Ray VFB, but have closed it, this button allows you to open it again. The same can also be achieved with the showLastVFB() MaxScript method of the V-Ray renderer.

Enable built-in frame buffer - Enables the use of built-in V-Ray frame buffer. Due to technical reasons, the original 3ds Max frame buffer still exists and is being created. However, when this feature is turned on - V-Ray will not render any data to the 3ds Max frame buffer. In order to preserve memory consumption we recommend that you set the original 3ds Max resolution to a very low value (like 100x100) and turn off the 3ds Max Virtual Frame Buffer from the common 3ds Max render settings.

Render to memory frame buffer - this will create a V-Ray frame buffer and will use it to store color data that you can observe while rendering and afterwards. If you wish to render really high resolutions that would not fit into memory or that may eat up a lot of your RAM not allowing for the scene to render properly - you can turn this feature off and use only Render to V-Ray raw image file feature.

Get resolution from 3ds Max - this will cause the V-Ray VFB to take its resolution from the 3ds Max common render settings.

Output resolution - this is the resolution that you wish to use with the V-Ray frame buffer.

Pixel aspect - specifies the pixel aspect for the rendered image in the V-Ray frame buffer.

Render to V-Ray Raw image file - when this is on, V-Ray directly writes to disk the raw image data as it is being rendered. It does not store any data in the RAM, so this feature is very handy when rendering huge resolutions for preserving memory. If you wish to see what is being rendered, you can turn on the Generate preview setting. You can specify either a .vrimg or an .exr file for output:

• If you specify a .vrimg extension, the resulting file can be viewed through the File > View image... menu of 3ds Max, or converted to an OpenEXR file with the help of the vrimg2exr tool.
• If you specify an .exr extension, V-Ray will write out a tiled OpenEXR file that can be used directly by 3ds Max or other compositing applications. The file contains all render elements for the image.

This part is good in rendering high resolution image while saving a lot of memories
Rendering it to Vray Raw Image File
VRAY FRAME BUFFER Vfb-vr10

To view the rendered image, go to File Menu then select View on the list and look for the file you have rendered.
VRAY FRAME BUFFER Vfb-vr11

Generate preview - this will create a small preview of what is being rendered. If you are not using the V-Ray memory frame buffer for conserving memory (i.e. Render to memory frame buffer is off), you can use this feature to see a small image of what is being actually rendered and stop the renderer if there is anything that looks wrong.

Save separate render channels - this option allows you to save the channels from the VFB into separate files. Use the Browse... button to specify the file. This option is available only when rendering to a memory frame buffer. If rendering is done only to a raw image file, the render channels can be extracted from that file after rendering is complete.

Save RGB and Save Alpha - these options allow you to disable saving of the RGB and Alpha channels respectively. This can be useful if you only want to generate other render channels. Note that V-Ray will still generate the RGB and Alpha channels, however they will not be saved.

Notes

• The V-Ray VFB does not display the G-Buffer layers (like Coverage etc.);
• The V-Ray VFB does not work with stripe rendering;
• Even though you select the V-Ray VFB as your output, the 3ds Max VFB is still created and thus takes additional memory. If you want to reduce that memory, you need to uncheck the Get resolution from MAX option, set the 3ds ?ax resolution to a low value like 100 x 100, and then select your real output resolution in the V-Ray VFB options.
• If you have selected an output image file from the Common tab of the Render Scene dialog, V-Ray will fill out the 3ds Max RFW, and this will be saved as your image. If you want to save the V-Ray VFB instead, you should use the Split render channels or Render to V-Ray raw image file option of the V-Ray VFB.

creds goes to ronel. I only posted the original source of the doc. I found some wrong info on the doc above but I am sure the help files at spot3d.com can explain them better than me.
