To speed up the Surface Editor, increase the size of the preview sphere visible at the top of the Surface Editor, or set the 'Refresh Rate' to 'Manual' in the Surface Editor options.
Our free db&w Tools (available for free at http://tools.db-w.com ) include nodes that complement infiniMap, such as a simple colour correction node or a node to convert colour spaces.
On OSX the number of open files per process is limited to 256 files as a default. As a result of this, infiniMap can use around 200 images per session.
This limit can be increased, but requires some work in Terminal. The line: limit maxfiles 512 1000000
needs to be added to the file /etc/launchd.conf (if it doesn't exist then it needs to be created) and increases the limit to 512 files. This is a plain text file. It will be active after a reboot.
