In some cases of the Linux operating system the generated license file doesn\u2019t seem to get read properly and fails to activate the copy of SHAPES. The problem are specific line-breaks in the license file and the current solution is to re-create the license file from scratch on the target system.<\/p>

  1. Create a new text file.<\/li>
  2. Enter the license data line by line, based on the license file which has been sent to you. The file is a plain text format and can be opened in any text editor.<\/li>
  3. Save the file with the same name as the generated license file.<\/li>

    The SHAPES menu gets created through a standard startup script. However, beginning with Maya 2022 Autodesk has introduced new security features and startup scripts are not allowed to run by default. It is possible to disable this behaviour from Preferences > Security<\/strong>. After a restart the menu should show up as expected.<\/p>

    Still, there are instances where scripts don\u2019t run even if the security features are disabled. The cause for this is yet not known and it doesn\u2019t affect the overall functionality of SHAPES.
    If you experience this issue the most simple solution is to create a shelf button which calls the SHAPES UI with the MEL command: SHAPES<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

    This issue is restricted to the Windows platform when loading a mesh into SHAPES which exceeds 35k polygons. The problem is related to evaluate the mesh during the symmetry mapping process. The current workaround is to disable Symmetry Mapping through SHAPES Menu > Symmetry > Symmetry Mapping<\/strong>. This way the mapping process is bypassed and mirroring of target shapes is based on position rather than topology.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

    Sometimes it can be resolved by resetting the prefs, though there is no guarantee.<\/p>

    A simple solution is to right-click one of the resize buttons and choose a preset size.<\/p>

      The SHAPES license allows you to install it on two computers but only one may be used at a time. If you have one installation running in your office it\u2019s within the license grants that you have the second copy running at home, as long as you are the only one using both computers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

      No, SHAPES is only needed when you want to create or edit a blend shape setup. SHAPES only uses default Maya nodes to make the scene files compatible with other environments which don\u2019t run a license of SHAPES.<\/p>

      An exception are the weight driver, ramp weights and weights server nodes. These nodes are installed along with SHAPES but can also be downloaded for free<\/a> to guarantee full compatibility. Furthermore the nodes are Open Source under the MIT license with their source code available on GitHub<\/a>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

      SHAPES has been tested with various setups and rig configurations to make the process as easy and stable as possible. However, rigs can be build in a magnitude of ways and the possibilities are endless. Working with blend shapes in a complex rig can be very difficult, expecially when some requirements are not met. If you run into issues it\u2019s quite possible that you scene contains information which hasn\u2019t been forseen. Please contact us<\/a> with a detailed description of your problem and the error as printed in the script editor of Maya. Also, usually it\u2019s very helpful for us to be able to look at the scene. If you can\u2019t share the scene file because of production regulations try to recreate the error with a simplified scene that you can share. The more information the better we can help you solve the issue.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

      When using SHAPES Maya often gets unstable. What can I do? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

      \n\t\t\t\t\t\t\t\t\t

      Since SHAPES basically only uses standard Maya functionality it usually doesn\u2019t influence the stability of Maya. The only known problem can be the extensive use of undo during the work. Undo can cause differences between the scene state and what SHAPES displays in it\u2019s window. These differences then lead to false interpretations by the user and unexpected results. It\u2019s always a good practice to use undo as little as possible when working with SHAPES. Also, incremental scene saving is highly recommended, as it is with all kinds of work.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

      You only need to load the setup created with the evaluation version into the commercial version of SHAPES and save your scene again. This will eliminate the pop-up.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

      Where I can get the current version of SHAPES for a commercial license? I don\u2019t see a customer login. <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

      You can simply download the evaluation version from the front page<\/a> and use your license details to activate your copy of SHAPES.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

      I need to pass a rig created with SHAPES to a client. Does he need to have SHAPES installed as well in order to work with the scene? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

      No, SHAPES is only needed when you want to create or edit a blend shape setup. SHAPES only uses default Maya nodes to make the scene files compatible with other environments which don\u2019t run a license of SHAPES.<\/p>

      An exception are the weight driver, ramp weights and weights server nodes. These nodes are installed along with SHAPES but can also be downloaded for free<\/a> to guarantee full compatibility. Furthermore the nodes are Open Source under the MIT license with their source code available on GitHub<\/a>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

      What is the weight driver? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

      The weight driver can either be used as a vector angle based reader node, much like the Michael Comet\u2019s pose reader node or a RBF solver. It\u2019s part of the SHAPES installation but also available as a free node to allow scene compatibility with environments not running a license of SHAPES. The weight driver node can be downloaded from the brave rabbit tool page<\/a> and the source code is available on GitHub<\/a>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

      The ramp weights node allows to control blend shape target weights interactively to create partial or split shapes. It\u2019s part of the SHAPES installation but also available as a free node to allow scene compatibility with environments not running a license of SHAPES.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

      The nodes are part of the SHAPES installation. It\u2019s not necessary to install these separately for the computer where SHAPES is installed. For any other computer the nodes can be downloaded for free from the brave rabbit tool page<\/a> or through the available Open Source repositories on GitHub<\/a>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
