VFB+ : A Feature-rich Extension to the 3dsmax Frame Buffer

Date Updated: 

VFB+ 2.5 Released

Click for Change Log

 Introducing VFB+ v2.5, the advanced virtual frame buffer for Autodesk 3dsmax.

VFB+ works with any renderer which uses the 3dsmax frame buffer, such as Scanline, Mental Ray, Final Render, IRay, VRay (when not using the VRay VFB).

The frame buffer has been designed and heavily tested to fit smoothly into any production pipeline, and to streamline the rendering workflow for anyone who renders in 3dsmax.

Version 2.5 is faster, supports any bit depth, and packs a multitude of new features. It works with any renderer, provided it is using the 3dsmax frame buffer (e.g. - V-Ray render will work when not using the V-Ray VFB).

A partial list of features:

  • Support for 16-bit and 32-bit per channel (HDR) images and color correction.
  • Various correction controls including exposure, gamma, multi-channel curves, vignette, chromatic aberration, bloom, blur/sharpen, speckle reduction, noise reduction, etc.
  • VFB+ is active while rendering, including tweaking of color correction and stamping.
  • Captures Render Elements, G-Buffer channels, and RTT elements as well as the main pass.
  • Composition guides help you tweak your image.
  • Pixel Aspect Ratio correction display.
  • 4 different A|B comparison modes.
  • Display modes for all channels.
  • Support for 3D color LUTs.
  • Realtime RGB Histogram.
  • Rich graphics stamping system with virtually any imaginable variable including arbitrary MAXScript expressions.
  • Fully documented.
  • Customizable interoperability options.
  • MAXScript interface provides access to almost all features.

A 30-day fully functional trial version is available for download.

Are you aware of the hotkeys?

Are you aware of the hotkeys? A, C, R, G, B make it faster than using the dropdown.

Show Alpha Channel button

I would like to see Show Alpha Channel button as a separate button or even make all channel buttons as separate small buttons instead of drop down menu which we have in version 2.2. In current version I have to click button to see Alpha Channel and find Alpha in menu instead of just one click. I like how it was done in vanilla max VFB for fast switch between Alpha/RGB colors. In VFB+ I cannot fast switch between Alpha and RGB at the same time looking at the rendered image because I have to look at the drop down menu for every switch.

Gamma Switch button

Thanks, I will use Preferences -> Color Correction -> Save Mode set CC Disabled, 1.0 Gamma.
Also, I would like to see the Gamma 1/sRGB switch button on main VFB+ panel to quickly see the difference between linear work space and sRGB similar as it was done in Vray VFB with sRGB button at the bottom.

Apply color correction to image sequence bug

I wanted to check what "Apply current color correction to image sequence" button does. I clicked on this button and then I clicked Cancel. 3dsmax freezes for about 1 min after that.

Thanks, I'll make a note of

Thanks, I'll make a note of fixing this.

In the meantime you can either override the gamma in the VFB+ color correction to 1.0, or in Preferences -> Color Correction -> Save Mode set CC Disabled, 1.0 Gamma.

VFB+ saves wrong gamma

I use Gamma 2.1 in 3dsmax. I have Input Gamma 2.1 and Output Gamma 1.0 for bitmap files. This means when I save image file from Vray VFB or Scanline VFB it will be saved in linear color space. But when I save the same image file from VFB+ the images saved with gamma 2.1 instead of 1.0. Make a quick test. Set gamma settings as I have and render sample object using Vray VFB, Scanline VFB, and VFB+ saving the image file from each VFB to .TGA. The saved images from Vray VFB and Scanline VFB will be identical but image saved from VFB+ will be brighter because it was saved with gamma 2.1 instead of gamma 1.0. I think, this is a bug which has to be fixed.

VFB+ accurately represents

VFB+ accurately represents the maximum depth provided by the renderer. If the Scanline renderer does not generate a 32-BPP buffer internally, there will not be 32-BPP data in VFB+. As far as I can tell the Scanline renderer uses a 16-BPP buffer at most.

"Support for 16-bit and 32-bit per channel (including HDR) images and color correction."

does this mena that I can save 32bit frames also using the scanline render?

for instance..actually i cant save fumefx renders with scanline in 32bit .exr, i can save 32bit but when i import in comp the sequence it has 16bit depht

Thanks for the support Shawn :)

I've been happily using VFB all week. Love it! I think AD should buy it from you! Anyway, glad you've built it. The filmstrip and split screen are really nice in my book. Other features will probably find a place for me too.
