The following table contains numbers and corresponding descriptions for issues fixed in this release since the Mudbox 2013 release.




With some meshes, extracting a texture maps using ray casting method may produce black artifacts in the output map.


Painting with Tangent mirroring on an object that contains triangles may cause the UVs and display to become corrupted.


Ctrl + S (Save Scene) is not saving the correct file size.


When Gigatexel Engine is on, creating a new paint layer or Edit Stencil will cause tiles to unload momentarily and display blue


Edit Stencil with stamp and stamp randomize on doesn't work.


Flatten to UV Space with blur or clone brush selected, and stencil on, causes crash.


The Blur tool strength always resets to default setting, doesn’t keep the user setting.


3Dconnexion - Dolly operation (zoom) is not working properly.


Object types should be grouped together in Object List


Create Turntable Movie status message is incorrect when Movie Format is set to Antialias.


3d curves that are flipped with mesh do not work as expected.


Texture is not transferred with "Send to Maya…" option when using Chinese or Japanese version Maya.


Snap to Curve doesn't recognize the spatial distance when sculpting, and will snap to a curve on mesh behind.


Environment variable MUDBOX_DATA_PATH is not working correctly.


Press Ctrl + lasso/marquee to deselect UV Shells causes Mudbox to hang.


Select Curve by Marking Menu will sometimes select the wrong curve.


Linux: The System Information dialog doesn't open.


Stroke on curve ignores the transformation on view curve.


Sculpt strokes that cross 2 meshes do not undo properly when a curve crosses both meshes.


Snap to 3d  curves doesn't work after transforming mesh.


Create Curve with "Snap to Curve" on, the cursor always snap to the curve that is being created.


With some systems The Grab brush will cause rendering artifacts making it difficult to see the effect of the brush.


Stroke on Curve ignores the closed curve area.


Preferences >User Interface > Expert Mode options are not working properly.


Toggling the Add subdivision level > Smooth Positions option corrupts existing subdivision levels


3D curves render at a very low level of detail or not at all on meshes that have been scaled very small.


 Delete faces operation does not handle mixed meshes correctly. This may cause artifacts after subdividing.


Textures are proxied when Gigatexel Engine is turned off.


File > Export Selection.., to a .mud file is exporting everything in the scene.


The Grab tool will not work on mirrored side of mesh if cursor is obscured by another mesh.


Export FBX file doesn't save texture map correctly with AMD graphic cards and Windows only.


Flood From Camera and Adjust color will affect a locked paint layer.


The high resolution textures will not load properly or be paintable after importing a ptex.mud file into scene with existing mesh set up for PTEX.


Installation: Unable to insert additional file and folder when creating deployment.


If you add files during deployment, deployment is created but when it is run it fails and does not install Mudbox.


If a stencil source image is changed in external application, Mudbox may hang or crash when the image is being refreshed.


Mac OSX: "Re-Import from PSD…" produces bad texture images with some AMD graphic cards.


Crash after creating joint and deleting highest subdivision level.


Paint layer format is always 8bit when importing from an PTEX file


3d curve does not updated properly when sculpt layer opacity is changed.


Deleting a mesh with curves that cross multiple meshes may cause crash


Lasso and marquee selection doesn't work when cursor is off the mesh


Vector Displacement Maps with Vector Space set to Absolute Tangent may cause seams at UV shell border.


Smooth Curve then undo, then redo, causes curve end to snap to origin


Extract normal and displacement map may produce artifacts or crash with certain meshes.


Curve ring cursor is sometimes offset or disappears from the end point of the 3d curve.


Very slow performance when creating joints and bones for some very dense meshes.


When painting on mesh with overlapping UVs, rectangular artifacts may appear in the texture. The paint preference "Paint on overlapping UVs" has been added to fix this for most cases.


Transferring a paint layer from a regular mesh to a PTEX mesh, where that regular paint layer is not 2k x 2k, the textures will be wrong and exporting them will fail.


Working with dense triangle meshes from scan data is very slow.


Duplicating an object will add "copy" to object name.


Extract Texture Maps with Map Type PTEX and File Name set to relative filename will cause hang.


Mac OSX 10.8.x: Screen Space Ambient Occlusion viewport filter is broken on AMD graphic cards.


When the camera is orthographic, you can see curves through the back of an object.


Edit > Validate Meshes should operate only on the selected mesh.

This section lists known limitations and workarounds for Mudbox 2014. Please report any additional issues using the online bug reporting form at: or from the Help > Report a Problem menu item in Mudbox.




The Gigatexel Engine stops working intermittently after assigning a new material or Ptex setup.

Workaround: Toggle the visibility of the offending paint layer on and off, create a new paint layer (can be empty or hidden), or save the file and reopen it to restart the Gigatexel Engine.
You need to start the Gigatexel Engine with this workaround before painting, otherwise textures on some tiles will go missing.


During installation there may be an error message that says the product key may be invalid and to re-enter it.

Workaround: Click OK on this dialog, click Next button again, and if product key is valid the installation continues.


Mudbox on Linux does not get pressure events from Wacom tablets with Fedora 12/Red Hat 6, QT 4.5. You can find more details in the bug report here:

There is a patch for Qt here:


Files that include 16 bit TIF maps will show errors with "Send to Maya..." operation.


Mudbox crashes if the extraction map output file name contains %S in string (for example: AO_(%S).bmp).


Creating a joint with Topology Weights doesn't work properly with non-4-sided meshes. Workaround: Use alternative Weights method.


If the level of the source model is not the current level when extracting a map, the detail of lower sculpt layers will be missing.  Workaround: Ensure you display the required subdivision level before extracting the map, or select the current level in the Extract Texture Maps window to get the correct result.


Transfer paint layer works incorrectly if target and source have overlapping UVs.


When using a non US-English standard keyboard, some of the hotkeys may not work. Workaround: Set your IME to "English - United States" while using Mudbox. For more information see your operating system documentation.


When painting or sculpting with symmetry ON, sometimes the result will not appear on the opposite side. Verify that you have "Falloff based on Facing Angle" turned off.


The Transfer Details function works best on objects that are the same size, or larger than the default Mudbox meshes. If the transfer produces artifacts on the target mesh, try scaling up the source and target meshes to the same size as the default head mesh.


When using the option “Send to 3ds Max…” changing the units between Max and Mudbox may cause unpredictable results.


When the amount of texture data exceeds the available GPU on your machine, the effects brushes draw red temporarily if "Solo as Diffuse" is ON for a paint layer.

Workaround: Once the stroke is done, the brush correctly applies the effect and the result is correct. You can turn off the Gigatexel Engine in the Render preferences (which effectively disables the paint buffer) and the effects brushes will work correctly.


If a portion of a curve on a mesh is obscured (for instance, if a portion of the curve is on the back side of an object) and you use Stroke on Curve" with mirror ON, results may be incorrect.


When creating 16 bit integer tiff layers in Mudbox, Mudbox processes and stores them as floating point pixels. To save 16 bit integer tiffs, export the paint layer as such.


On Mac OS X the installer may hang at end of a successful installation. It is recommended to force quit the installer. Mudbox will then run normally.


On Linux, if Mudbox crashes when starting up with an error message such as "mudbox: symbol lookup error: /usr/lib64/ undefined symbol: X509_VERIFY_PARAM_new", try the following workaround:
1. Install OpenSSL >= 1.0.0 if you haven’t already.

2. Point the old symbol link to the 1.0.0 version, like "ln -s -f /usr/lib64/ /usr/lib64/"


An environment variable MUDBOX_EXPOSE_8K exposes "8192" in the Create New Paint Layer "Size" option. (It will not be exposed if less than 512 MB GPU available. 1.5 GB or more recommended).


Extracting a displacement map with "Preview as Bump Layer" will display the bump as black. Deleting the bump map and importing it again will fix the issue.


Painting 8k (8192x8192) resolution textures can be unstable with some NVIDIA graphic cards with lower graphics memory.


Some SDK examples cannot compile because of QHash.

Workaround: If there is a syntax error with Qt header files when compiling the SDK examples, adding the correct Qt subdirectory to the #include declaration may fix it. For instance #include <QHash> would become #include<QtCore\QHash>.


On Mac, the (License Transfer Utility) does not launch.

Workaround: Run command line script /Applications/Autodesk/Adlm/R7/ <productkey> 2014.0.0.F -d "SA" -l "<language>"

Where <product_key> is the Mudbox 2014 product key 498F1, and <language> is en-US for English, ja-JP for Japanese, de-DE for German, fr-FR for French


The menu option "Send to 3ds Max..." does not start the 3ds Max application. 3ds Max must already be running for "Send to 3ds Max..." to work. This issue is fixed in Service Pack 1.
