--- --- --- ## **Histogram** --- --- --- --- ## **Layers** --- --- --- > Macro (anchor) --- ### **Save and Load Layer Presets** There are several types of layer presets: presets for a single layer, presets for a folder of one or more layers, and presets for a full layer tree. You can also load a legacy preset for global color corrections (vccglb) saved with the previous VFB 1 available in earlier V-Ray versions. You can only load vccglb preset files via the **Load layer tree preset** ()** **button, but you cannot save them with the new VFB. The preset for a full layer tree (vfbl) can be saved or loaded from the respective **Save layer tree preset **() and **Load layer tree preset** ()** **buttons in the Layers tab. The presets for a folder (vlpdir) can be saved and loaded from the context menu of a folder. Such presets can also be loaded or previewed from the Layer/Filter presets menu if it points at its location or through the **Load layer tree preset **() button. The presets for a single layer (vlpct, vlpexp, vlpwb, vlphsl, vlpcl, vlpcrv, vlplut, vlptm, vlpicc, vlpvgnt, vlpsrc, vlpdzr, vlpshb, vlplfx) can be saved or loaded from the context menu of an existing layer: right-click on the layer and select **Save **or **Load**. The following presets for single layers are available: **vfbl **– A preset for a full layer tree. **vlpdir **– A preset for a folder of one or more layers. The vlpdir presets are saved from the context menu of a folder. **vlpct **– A preset for a single Constant layer. Can be saved from the context menu of the Constant layer. **vlpexp **– A preset for a single Exposure layer. Can be saved from the context menu of the Exposure layer. **vlpwb** – A preset for a single White Balance layer. Can be saved from the context menu of the White Balance layer. **vlphsl **– A preset for a single Hue/Saturation layer. Can be saved from the context menu of the Hue/Saturation layer. **vlpcl **– A preset for a single Color Balance layer. Can be saved from the context menu of the Color Balance layer. **vlpcrv **– A preset for a single Curves layer. Can be saved from the context menu of the Curves layer. **vlplut **– A preset for a single Lookup Table layer. Can be saved from the context menu of the Lookup Table layer. **vlptm **– A preset for a single Filmic tonemap layer. Can be saved from the context menu of the Filmic tonemap layer. **vlpicc **– A preset for a single ICC profile layer. Can be saved from the context menu of the ICC profile layer. **vlpvgnt **– A preset for a single Vignette layer. Can be saved from the context menu of the Vignette layer. **vlpsrc **– A preset for a single Source layer. Can be saved from the context menu of the Source layer. **vlpdzr **– A preset for a single Denoiser layer. Can be saved from the context menu of the Denoiser layer. **vlpshb **– A preset for a single Sharpen/Blur layer. Can be saved from the context menu of the Sharpen/Blur layer. **vlplfx **– A preset for a single Lens Effects layer. Can be saved from the context menu of the Lens Effects layer. ## **Stats** --- ## **Log** --- ## **Collaboration** --- --- --- --- ## **VFB Shortcuts** --- These shortcuts navigate through the VFB image. Please note that the VFB window must have the current focus for the shortcuts to have effect: > ℹ️ 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. > ℹ️ VFB Shortcuts are customizable in the VFB > Options > Shortcuts tab. ## **VFB IPR Options** --- > Macro (anchor) ## **Region Render** --- Region rendering is available in both IPR and Production modes. It allows the isolation of parts from the whole frame for rendering. --- > Macro (anchor) ## **Saving Files With Render Region** --- There are two ways to save the whole frame with the region render. **Single channel .exr files** are saved through: - **Render Setup **>** V-Ray **tab > **Frame buffer **> **Separate render channels** (V-Ray ignores 3ds Max's Image Region option residing in the 3ds Max native file output dialog under Setup > OpenEXR Configuration window.) - **VFB **> **File **> **Save current channel** **Multi-channel .exr files** set to save the whole frame are saved through: - **Render Setup **>** V-Ray** tab > **Frame buffer** > **V-Ray raw image file **+ **VRayOptionRE** with **EXR data window** set to **Whole Image **(Multi-channel .exr files set to save full frame instead of just the render region.) - **VFB **> **File **>  **Save all image channels to single file** ## **Notes** --- - VFB does **not** display the G-Buffer layers (like **Coverage** etc.) - VFB does **not** work with strip rendering - VFB does **not** work with rendering to fields - Even when the V-Ray VFB is enabled, the 3ds Max VFB is still created and thus takes additional memory. To reduce that memory, uncheck the **Get resolution from Max** option, set the 3ds Мax resolution to a low value like 100 x 100, and then select your actual output resolution in the V-Ray tab > Frame buffer options in the Render Setup window. - If you have selected an output image file from the **Common** tab of the **Render Scene** dialog, V-Ray fills out the 3ds Max RFW, and this is 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 tab > Frame buffer options in the Render Setup window. - The OpenEXR file format is an open file format for high dynamic range images originally developed by Industrial Light and Magic. The official site of the OpenEXR file format is [http://www.openexr.com/](http://www.openexr.com/) - When using the IPR right-click options, the primary 3ds Max window needs the cursor focus to use Ctrl+Z to Undo. - If [Lens Effects](https://docs-chaos.atlassian.net/wiki/spaces/VMAX/pages/113587016) or the [VRayDenoiser](https://docs-chaos.atlassian.net/wiki/spaces/VMAX/pages/113575403) render element are enabled, then the RGB Color channel is saved with the name RGB_color and the effectsResult channel is saved as effectsResult when saving all channels from VFB. - If an 8-bit file is saved through the VFB or the Render Output / Save image settings, a color space with Gamma 2.2 is embedded into the final output image. If a 32-bit (exr, hdr, tif) image is saved, it remains linear and relies on the external image viewer to handle the display color space. - The VFB test resolution is ignored for command-line rendering and Backburner jobs. The Test Resolution button is inactive in IPR if **Fit resolution to VFB** is enabled. - The Enhance image on Chaos Collaboration feature is supported for 3ds Max 2022 and newer.
