When opening a project created by a 1.x version of Lightform Creator, you may see the following warning message if your project has "structure" data.
Due to changes in Lightform Creator 2.0, this type of data is no longer supported. This document explains what has changed, and why. Even if you've never encountered this warning message, you will find value in reading through this documentation in order to understand how the new Perspective Warp tool works.
What to Do Next
If your project looks visually incorrect
- If your project is a critical work-in-progress, you should quit Lightform Creator 2.x without saving the project. Then continue using Lightform Creator 1.x until you no longer need the project.
- If your project is simple or non-critical, you need to rework it using Lightform Creator 2.x.
If your project looks visually correct
Save your project and you will never see the warning again.
How it Previously Worked
Refer to the Editing Modes page to learn about how the new Perspective Warp tool works.
Upon selecting the Structure tool in the toolbar, the underlying structure of a selected surface became editable. By default, you could drag the structure corners to modify the deformation. This default deformation was a starting point.
If you needed to go deeper, you could double-click on the structure and manually adjust the underlying control points.
Even in a relatively coarse structure, this was a tedious process.
With a more dense structure, it became very time-consuming to use.
An additional factor that you had to consider when using the old Structure tool: the structure boundary was a mask for content. Since a surface also acted as a mask, there were potentially two masks to maintain for each surface. This often resulted in unexpected behavior, with content sometimes not being visible due to it being masked by the structure, but not the surface, or vice versa.
