The following describes known limitations related to presentation, effects, and display in Mudbox.
Save Screen Image produces tiled image
The Save Screen Image feature can produce an image with a visible tiled appearance when saving images larger than the default screen resolution whenever the Tonemapper viewport filter is turned on.
Workaround: Set the Adaption Time and Epsilon settings in the Tonemapper filter to zero before using the Save Screen Image feature.
Viewport filter settings not saved
Viewport filter settings are not saved with a Mudbox scene file (.mud).
EXR images (32 bit) for reflection maps
When choosing images for reflection maps, keep in mind that the amount of GPU memory required to display them can be quite large. For example, a 4K x 2K 16 bit/channel map requires Mudbox to produce six 4k x 4k 16 bit/channel textures to load on to the GPU (1 for each surface of a cube). This amounts to 768 megabytes of textures for the environment map alone. This drastically affect the performance of any computer system and graphics card.
Workaround: The Mudbox team recommends that users limit their reflection maps to 2k x 1k as the maximum resolution. Most users will not even notice a degradation in quality when using 1k x 512 reflection maps. These resolutions would require 192 Mb and 48 Mb respectively.
Graphics Interchange Format (GIF) images are not supported for use as stencils, stamps, or image planes in Mudbox currently.
Workaround: Convert the GIF image to another supported file format. For example, PSD or TIFF. For more information, see Image file formats
Texture filtering doesn’t update consistently
Turning the Use Texture Filtering preference on or off doesn’t appear to have an immediate effect on the display of the textures in the 3D View.
Workaround: Turn the texture channels in the Paint Layer window off and then on again to cause a manual refresh of the associated paint layers.
