Best practices for presentation

Mudbox takes advantage of your computer’s graphics card processor (GPU) to produce high quality rendering and visual effects in real time. The following best practices and tips related to The features for presentation can assist with optimizing rendering and interactive performance within Mudbox.

Area | Best Practice or Tip
--- | ---
Shadows | Turn off shadows for any lights that do not require them or reduce the size of the Depth Map Resolution to decrease the GPU memory requirements. A shadow depth map is created for each directional light when its Cast Shadows property is turned on. The resolution of a shadow depth map affects the quality of the shadow and the amount of GPU memory required.
Lights | Keep the number of lights in the 3D View to a minimum to improve interactive performance. You can use image-based lights if you want a more evenly lit scene. Minimize the resolution of the high dynamic range images (HDRI) that are used for Image-based lighting to reduce their GPU memory requirements.
Viewport Filters | Turn off the viewport filters when they are not required to improve interactive performance. These post-processing effects are updated with each display update of the 3D View. Turning on the viewport filters (Ambient Occlusion, Depth of Field, or Tonemapper) requires the allocation of additional texture memory on the GPU.
Materials | The Mudbox material is the default material and should be used for the majority of your work, provided you are using a qualified graphics card. Keep the number of materials assigned to objects in the 3D View at a minimum. Assigning textures to each of the material’s texture channels will increase memory usage on your computer’s graphics card. Interactive performance may be reduced depending on the number, resolution, and bit depth of each assigned texture. If your computer is equipped with an older, unsupported, or lower performance graphics card, you can assign the Simple Blinn material for sculpting. It provides basic color properties but does not provide texture channel capabilities for 3D painting.
Paint Layers | To reduce GPU memory requirements, create lower resolution paint layers with lower bit depths (when possible) and turn off the display of any paint layers that are not required. Merge any paint layers when possible. For more information, see Image bit depth and texture extraction and Merge paint layers. Mudbox has proprietary features for minimizing GPU memory requirements when displaying paint layers. The number of paint layers assigned to a model, their image resolution, and bit depth impacts GPU memory requirements.
Wireframe Display | Turn off Wireframe display mode when it is not required. Wireframe display mode can increase the time to refresh the 3D View during interactive operations (sculpt, track, dolly, tumble, and so on) as the subdivision level on the model is increased.
