Lumion 12.3.1.1 Hotfix (only for Lumion 12.3.1 users)

After Lumion 12.3.1 was released, some of you encountered issues with Layers and interface responsiveness that our developers have now fixed.

Important: To install this Hotfix, Lumion 12.3.1 is required and the patching process will not work with other versions of Lumion. The hotfix will be included in a later Lumion 12 standalone update.

 

1. Resolved issues:

  • Mouse interactions with the user interface are more responsive and no longer sluggish in heavy Projects or Projects with low framerates.
  • The Layer tab is more responsive when renaming Layers.
  • The Layer name display has been improved.
  • The name of Hidden Layers is now displayed when hovering over the Show/Hide icon.
  • Layer names being displayed as numbers: this is now based on the available on-screen space instead of the number of Layers.
  • Layer states no longer reset when loading a Project.

  • Please choose 'overwrite' when Windows asks you if you want to overwrite the existing file.
  • You need to have Administrative rights to write to this folder.
  • If Windows does not ask you to confirm, you have moved the '.ZIP' file and/or unzipped it to the wrong location.
  • In case you get an 'Access Denied' error message when extracting the files to the installation folder, please double-click the hotfix .ZIP file to open it and then drag the contents to the folder instead.
