Dear Friends of 3DE!

3DE4 R4b4 can now be downloaded from the download area of our website. We mainly fixed a number of bugs and added some improvements:

• There is a new adjustment script for optimizing 3D camera paths. This only makes sense in connection with the locked channels constraint and additional survey data (e.g. for bringing imported moco move data into survey space)
• Another new adjustment script allows to optimize the Y component of selected CVs of curves found in the curve editor. This can be used to calculate dynamic distortion curves in cases where no gridshots are available.
• Lineup Controls now allow it to drag multiple "lineup only" points simultaneously (hold down SHIFT while click-dragging left mouse button).
• Fixed an annoying bug which caused 3DE not to rename a new camera when importing its footage for the first time.
• Finally there is a new documentation available which describes how to develop adjustment scripts.

Please see changelog below for more details!

Cheers, Rolf
