To access your preferences, click the Preferences Tab in the main GUI. From here you can set up the way Knald performs
Enable Prefix: Checking this option will allow you to globally appended a prefix to each maps file name once saved. You can either edit the name in the input field or use the various dropdowns to choose a preset. For example, If your saved normal map is going to be called example.tga and you choose the T_ prefix, the file will then be renamed to T_example.tga
Suffix: Here you can change the suffix that each map will have appended to its file name once saved. You can either edit the name in the input field or use the various dropdowns to choose a preset. For example, If your saved normal map is going to be called example.tga and you choose the _normal suffix, the file will then be renamed to example_normal.tga
Change mesh axis so that Y/Z is up Changes the direction of the up axis in the 3d preview window. Change this to match the up direction of your exported mesh.
Enable Anti-aliasing: Enables Anti-aliasing in the viewport. This requires a reboot of Knald to take effect.
Use per vertex tangent space: Toggles between per vertex tangent space1) and no tangent space derivative when viewing imported meshes. This requires a reboot of Knald to take affect.
Prioritize Integration Performance: Checking this option allows Knald to prioritize integration, Mesh AO & Transmission speed over viewport responsiveness.
Pack Displacement into the Alpha of a Normal Map: Checking this option will automatically pack the Height Map/Displacement Map into the Alpha channel of the Normal map when saved.
Use Alpha by default: Checking this option will automatically force Knald to use an Alpha channel by default, when processing Normal/Derivative maps. Using an Alpha channel will cause the masked area to be read as flat.
Enable Copying of Alpha Channel data to Clipboard Checking this option will enable the copying of Alpha channel data to the clipboard from within Knald. While Knald fully supports Alpha in the Windows clipboard, some applications fail to correctly interpret the data, requiring this option to be disabled.
Export Alpha Channel: This option allows a choice of multiple kinds of Alpha data to be written when baking is performed.
If the Soft Alpha from HP option is chosen and content is baked without anti-aliasing the Hard Alpha from HP will be used as a fall-back.
Use FBX Tangent Space: Check this to use the embedded Tangent Space held within an imported FBX file.
Prompt to Save Settings on Exit Enables notification to save modified settings on exit.
Display Update Notifications on Startup: Enables notification of any available updates to Knald.
Display Update Notifications for Beta Releases: Enables notification of any available Beta Releases of Knald.
Enable Tooltips: Checking this option will turn tool tips on/off at a global level.
