How To Create A Frame Buffer For A Camera On Uctronics 3.5 Inch 480x320 Tft Lcd Using A Frame Buffer
This page provides information on the New V-Ray Frame Buffer and its features.
Overview
The resigned Five-Ray Frame Buffer (VFB) is a 2nd generation V-Ray virtual frame buffer.
New VFB is available in 3ds Max 2018 or subsequently. Older 3ds Max versions only support the previous V-Ray VFB.
New VFB is much more than a render paradigm holder window. The new enhanced version provides a higher level of post processing adjustments and ability to modify your scene from inside the new VFB. Here is a list of old and new benefits yous should know:
- Paradigm preview:
Loads render elements channels via a dropdown list;
Works with display corrections;
Loads various 8bit and 32bit file formats, including V-Ray resumable files;
Image comparison betwixt 2 or four renders;
- Paradigm management:
Keeps the rendered image in total 32-flake floating point format;
Tin can store history of rendered images with their post rendering corrections;
Tin relieve corrected output to diverse image formats;
- Prototype editing and post processing:
Fix Colour Corrections to rendered prototype and its elements;
Blended mode for Back to Beauty workflow including layers corrections;
LightMix command on lights contribution in the rendered paradigm;
- Scene editing:
Can modify actual lights values by transferring updated intensity and color from LightMix mode;
IPR camera navigation and focus control from inside VFB;
- Render management:
Denoiser control;
Region rendering command and test resolution;
Allows you to cull the society in which the buckets are rendered;
Automated render resolution adjustment in IPR when the new VFB window is resized;
| Carte du jour | Menu Options | |
|---|---|---|
| File | Save electric current channel – Saves the currently loaded channel to an epitome file format. Note that color correction layers are not saved. Save all prototype channels to divide files – Saves all the render elements to separate files. Press the options( Salve all paradigm channels to single file – Saves the prototype to a single multi-channel EXR or .vrimg file. Load prototype – Opens an prototype file to be previewed in the 5-Ray Frame Buffer. Batch image processing – Allows processing of multiple .vrimg files with the same layer tree changes at the same fourth dimension. | Salvage all image channels to separate files options Save VFB colour corrections to return elements – When enabled, all color corrections are saved to the render channels (equally opposed to only the RGB and effectsResult channels). |
| Batch Prototype Processing Input folder – Specifies a path to first images. Output folder – Specifies a path for the output images. Layer preset – Specifies a layer tree corrections preset.

Render History
The Five-Ray VFB keeps a history of previously rendered images, and lists each with a number, thumbnail, and textual details in the Render history panel. Up to iv images tin can be called from the history to be compared in the VFB (as shown beneath). History files are stored as .vrimg files in a user-specified binder. Return history settings can be configured in the VFB Settings window.
| | Enables or disables prototype A/B vertical comparison. Select images A and B from the render history. |
|---|---|
| | Enables or disables image A/B horizontal comparison. Select images A and B from the return history. |
| | Enables or disables image A/B/C/D comparing. Select images A, B, C and D from the render history. |
| | Saves the electric current epitome from the VFB to the render history. The prototype is placed at the elevation of the render history listing. |
| | Loads the selected epitome from the return history to the VFB. |
| | Removes the selected image from the render history. |
| | A search field where yous can filter the images based on the scene paths and notes. The filter text is selected when pressing the Enter from the keyboard. |
The keyboard keys from 1 to nine tin can be used to quickly load the first ix images from the history to the VFB.
The History panel with notes/name, resolution/fourth dimension, and shortcut cardinal info displayed. Correct-clicking on an image in the VFB history brings up a popular-up menu with some useful options.
Epitome Info window
Edit note – Allows you to add a text comment to the prototype; the comment appears beneath the epitome.
Set A– Sets the return equally A epitome for A/B comparison.
Set B– Sets the render as B paradigm for A/B comparing.
Load to VFB – Loads the selected image in the VFB (same as double-clicking on the prototype).
Delete– Deletes the selected image from history. The image is moved to the organization's Recycle Bin and can be restored from there if needed.
Load layers Loads the layer tree preset of the selected epitome.
Load 5-Ray settings– Loads the V-Ray settings used for the saved return.
Compare Five-Ray settings– Opens the Compare Five-Ray settings dialogue, where you can compare the render settings of saved renders.
Image Info – Opens a window containing detailed information virtually the image, including, but not limited to Camera, Aperture, FOV, Target Altitude, Five-Ray version, return time, and also custom attributes specified in the exr metadata of VRayOptionRE return element. Take in listen that the photographic camera values are saved in organization units. Too, the vrayrevison info displayed in the list is non related to the saved .vrimg file but to the current V-Ray build installed for 3ds Max.
Open up scene – Opens the rendered scene in the viewport. This option works as long as the initial file path of the scene has not inverse subsequently the return.
Re-create scene path– Copies the full path to the scene.
Copy project path– Copies the full path to the project.
Show in folder – Opens a file explorer with the corresponding epitome selected.
Reload history– Re-reads the history paradigm list. This may be needed if the history binder is updated outside of 3ds Max (e.g. from another 3ds Max session).
If you desire to continue the layers that come with the Max scene, turn the Car Load Layers choice off from VFB > Options > History tab. If you lot want to load layers from an external epitome, enable the Auto Load Layers choice and check how you save those images.
Layers
The redesigned V-Ray Frame Buffer includes a suite of color corrections and tools for adjusting the image. The tools are added as layers and displayed in a layer tree. You tin can enable or disable a particular tool using the visibility icon ( 
) to the left of its proper noun. The 
icon indicates that a layer is disabled.
Layers are but saved to .exr and .vrimg files written through V-Ray'south own output. Notation that the output in Render Setup > Mutual tab is written by 3ds Max then .exr files saved from there practise not have Layers saved.
When saving layers to an exr/vrimg file, V-Ray writes a flag indicating whether the color corrections are baked in the RGB channel. For example, if you save an exr from the VFB File menu > Salvage all image channels to unmarried file option, V-Ray creates an .exr file with corrections baked in. It also saves the layers as metadata and the flag that corrections are baked in. When loading images into the Frame Buffer, V-Ray checks if the image has corrections broiled (using the flag), and if such are plant, the layers are non loaded (from History panel > Load layers option or VFB File menu > Load image option) considering this causes double correction.
For more information on using the Layers, run across the Layers page.
| | Creates a layer. Multiple layers of the aforementioned type can be added. Binder – Allows group multiple layers; For more than information, see the Layers page. |
| | Deletes the selected layer(southward). |
| | Saves a layer tree preset. |
| | Loads a layer tree preset. |
| | Quick admission to custom layer presets. You must fix the path to it in the VFB Settings. |
| | Undo various actions related to layers such as create, delete, reorder or change a layer. |
| | Redo diverse actions related to layers such as create, delete, reorder or modify a layer . |
Each layer has a context bill of fare. Right-click to display it:
| Command | Description |
|---|---|
| Reset | Resets all changes done to the selected layer. |
| Salve | Saves the layer as a preset. |
| Load | Loads a preset for the selected layer. |
| Delete | Deletes the selected layer. |
| Save as LUT | Bakes all the color corrections to a LUT file. |
| New Layer | Creates a new layer. |
| Duplicate | Duplicates the selected layer. |
| Alloy Modes | Specifies how the selected layer blends with the outcome from all layers below it. |
Stats
The V-Ray Frame Buffer allows monitoring of different statistics and information nigh your scene in the Stats console. The verbal contents of the Stats changes depending on the scene, the rendering mode (interactive vs production, bucket vs progressive) and others.
Right-click to display a context menu, assuasive you to copy the Stats values.
Log
The Log panel provides messages about the return process. Verbosity control is available and you can filter the type of letters shown in the Log: All, Mistake Only, Error & Warnings, or Fault, Warnings & info. Additional options are available when you click on the Open options 
button:
Show progress – Shows a completion percent of each task (e.g. building Light Cache).
Wrap – Wraps longer lines in guild to avert horizontal scroll.
Undock– Docks/undocks the Log tab.
Notation that the V-Ray Log is also attainable via theEvidence log button.
The Log tab can exist detached and used equally a split up window or docked elsewhere.
Ctr+F opens a search field .
VFB Shortcuts
These shortcuts navigate through the VFB epitome. Please note that the VFB window must take the electric current focus for the shortcuts to have effect:

Please, note that when the Enable shortcuts option (VFB > Options > Shortcuts tab) is disabled, all 3ds Max shortcuts are expected to have effect, even if the VFB window is in focus.
VFB Shortcuts are customizable in the VFB > Options > Shortcuts tab.
VFB IPR Options
Existent Zoom – When enabled, scrolling does non zoom the pixels of the rendered image, but instead moves closer or further from the rendered geometry.
View Navigation – Requires a photographic camera view. Adjusts the view angle from the return in the VFB instead of in the viewport. But click and drag in the rendering area of the VFB window.
Pause– Pause/resume rendering when rendering with V-Ray GPU.
Re-initialize – Restart rendering.
Select object(Ctr+Click) – Directly select scene objects by clicking on them in the VFB rendering area.You can utilise the Ctrl + left mouse button keyboard shortcut instead.
Become object material(Shift+Click)– Pick a scene cloth from an object that is being rendered. You merely demand to click on that object in the VFB rendering area and the material editor opens with it. Yous can employ the Shift + left mouse button keyboard shortcut instead.
Set focus distance(Alt+Click)– Sets the target distance for the Depth of Field effect to the location clicked in the VFB rendering expanse. Yous can use the Alt + left mouse button keyboard shortcut instead.
Note that the keyboard shortcuts work only inside the VFB window.
Render Region
Region rendering can exist used in both IPR and Production modes to isolate only office of the frame for rendering. Usually, when a render region is used, you would like to salve the whole frame instead of the region only.
Saving single channel .exr files ignores the render region and always saves the full frame. This applies when saving the .exr from: Render Setup> Commontab > Common Parameters> Return Outputand Return Setup> 5-Raytab > Frame buffer> Separate render channels.(V-Ray ignores 3ds Max'southwardParadigm Region option residing in the 3ds Max native file output dialog netherSetup >OpenEXR Configuration window.)
Saving multi-aqueduct .exr files writes just the render region data in the file past default but it can be set up to save total frame instead. If the file output is saved throughRender Setup> 5-Ray tab >Frame buffer >V-Ray raw paradigm file, in society to save the render region with the rest of the frame, add together VRayOptionRE return chemical element and set itsexr data window option toWhole Image. Saving multi-channel .exr files fromVFB > Save all channels to single filesaves the render region when it is enabled from the VFB. This happens even if you lot accept selected a render region on top of the already rendered frame, without an bodily region used in the rendering process. To save the full frame from VFB, disable the render region.
