The temp folder is a folder for temporary files created by iClone during operation. You can define where temporary files are saved in the preferences settings.
Click the Choose...
button in the Temp Folder option and browse to a folder you wish to use as the temp folder.
Make sure the hard disk the temp folder is located on has sufficient free space especially when you are using iClone to produce high resolution videos.
You can select an external application for use as a texture editor with iClone. Textures edited using the "Launch" feature of the iClone material editor will open with the image editor selected in this section. (E.g. Adobe Photoshop)
Click the Choose ... button in
the Texture Editor option and browse to the executable
file of a suitable texture editor application.
Set the Undo times to decide how many actions you can Undo/Redo. The maximum is 99. A higher value requires more resources of your system.
