FIX VIEWPORT – OVERVIEW
The Fix Viewport Tool makes an aesthetically pleasing Maya viewport.
Add real-time reflections and soft shadows to your models with our “light rig” and fine-tune with our HDRI Skydome Browser .
Upgrade your viewport to the modern Standard Surface Shader and leave Maya’s outdated Lambert and Blinn shaders behind.
Don’t let the technical details of ACES and Linear Color Space hinder your artistic vision (Maya 2022 and above); manage your colors with ease.
Eliminate blandness from your viewport by using our view space presets and exposure/contrast sliders for grading.
Plus, there are many other features, such as preventing unsightly shimmering intersections and more!
Simplify your life and optimize your viewport instantly with the Fix Viewport tool.
NEW STANDARD SURFACE SHADERS
About Surface Standard (Maya 2020+)
The new standard surface shader in Maya has several benefits, including improved realism, user-friendly controls, faster rendering times, advanced features like subsurface scattering and anisotropic reflections, compatibility with other PBR workflows, and efficient handling of complex materials.
Unfortunately the shader may appear too dark in Maya’s viewport. The Fix Viewport tool solves this issue by adding a light-based rig with an HDRI Skydome for reflections, ensuring accurate rendering.
Note: Using Lamberts/Blinns/Phongs
If you’re using Lamberts and Blinns in Maya 2020 or newer versions, you should make adjustments to our tool:
– Fix Viewport > Advanced Mode > Camera viewport > Intensity (drop down) > Intensity Lambert/Blinn
IMPORTANT: 2022 ACES/LINEAR FIXES
Overview
ACES is a standardized color space used in the film and video production industry for consistent and accurate color management, providing a wide gamut and high dynamic range.
Despite the transition to the new ACES format (Maya 2022+), there are still issues to address, including confusion when upgrading old scenes and Adobe products lacking native ACES support.
The Fix Viewport Tool allows for easy switching between ACES and the older Linear Color modes, and we provide an additional tool called Match Swatch Color Space for correcting shader colors between the two modes.
The Fix – Switch To Linear
Switching back to Linear Color Space can help resolve color issues with imported files and your model/assets:
– Press the Linear (sRGB) button
– Press the No Tone-Map button
These settings can resolve wireframe anti-alias issues and map-painting problems, like skin-weight painting.
Switch Back To ACES
To return to Maya 2022 defaults color space:
– Press the ACES (sRGB) button
– Press the SDR-Video button
Wireframe and weight painting can be addressed in ACES by clicking on the following:
– No Tone-Map button
KNOWN ISSUES & FIXES
Viewport Renderer Support
Fix Viewport requires Arnold to be loaded though you do not need to be rendering in Arnold. HDR Skydomes in the viewport are only supported by using Arnold skydomes, though we hope that will change in the future.
Most shaders types of all renderers are supported, see below.
Shader Support
Most shaders (all renderers) are supported though we recommend Maya’s generic standardSurface shader (2020 and above) or Arnold’s aiStandardSurface (2017 and above).
Other shaders such as blinn/phong/lamberts work too but the specular/reflective properties of these shaders are not as good as standardSurface and aiStandardSurface.
Maya 2020 Circle Hole Issue
Maya 2020 can show with a big circle hole in the middle of the screen. To fix, refresh the viewport by running the following code twice or more. This code will be added in Zoo 2.5.5. In Zoo 2.5.5 you will also be able to hit the new refresh button (planned) and that will run this code too.
cmds.ogs(reset=True)
This issue due to an Autodesk bug and is not related to Zoo Tools Pro. You can also upgrade to 2022 where this issue is solved.
Maya 2020 Chrome Ball HUD Hidden
In Maya 2020 the chrome ball may be hidden, this is a known Autodesk bug and has been fixed in Maya 2022 and above.
To fix you can also wiggle the HDRI control or the code:
cmds.ogs(reset=True)
Unfortunately moving the viewport will hide the chrome ball again.
Rendering With The Setup
This light setup does not currently render in any renderer, Arnold or other renderers; this is because we are using Maya’s native directional lights. We plan to add a renderer switch so the light rig will work with all of our supported renderers soon.
I Can’t See The HUD Light Setup
To see the HUD controls you must have polygons, and NURBS Curves displayed in the show menu.
– Viewport Menu > Show > Polygons and NURBS Curves (on)
The HUD currently works with a 35 mm focal length on the camera.
If you’re zoomed in with a long lens, use the \ hotkey (hold and right-click zoom drag) until you see the HUD control and move it into frame then tap \ again to return to the correct lens zoom. We will solve this issue in a later version.
To hide the HUD Light display use Maya’s Layers under the Channel Box and turn off the visibility (v) of the layers named vpLight_geo_lyr and vpLight_ctrls_lyr.
Hide HDRI Light Viewport
To hide the HDRI and directional lights in the viewport, turn off lights in the viewport display menu.
– Viewport Menu > Show > Lights (on or off)
Switch The Light rig To Another Camera
Press Create/Reparent Light Button and any existing setup will reparent and constrain to the active viewport camera.
– Change your viewport camera to a new camera, make sure the viewport is active (grey line around it)
– Press the Create/Reparent Light Button in the Fix Viewport tool
