Backgrounds

A better way to position transform and gizmos is using backgrounds. Backgrounds in Curved poly editor are flexible elements, which can be used both as image references and as grids. Let's say they are background grids which can be assigned an image. We can add a backogrund with Add Background. Then we need to set it up. We can place it where we want using its position or extension gizmos. We can also control such positions in the Bacground Grid section of the Dedicated Inspector, which appears only if you cklick on one of the Background gizmos. Here you can also add an image, and controls the number of nodes in the grid, and their properties.

Fig. 1 Adding a new Background. On the right, the background grid working in Scene, on the right the Dedicated Inspector with a Background/Grid Section. Such section appears only when the grid is picked in scene.

Fig. 2 Another background example, this time with an image. In this case we have disabled the mesh renderer in Unity Inspector, in order to see the full background image behind the model curved edges.

Once your grid is set up, you can snap to it if Snap to Grids is active. The snapping happens on the edit pivot of the selection transform.

If you don't want this to happen at some point, you can always disable the snap to grids options, or even the grids visibility to hide them.

Since placing grids may take time, it is useful to save them. For instance We've have made here a set of reference grids which work good to shape small objects with some precision. I can now use Save Backgrounds to generate a backgrounds asset which contains them.

Backgrounds assets can also be edited in Unity Inspector, once generated. Stored Curved Poly Backgrounds can be reopened on need, while editing other shapes, with Load Backgrounds. Curved Poly Editor already comes with a little set of premade Backgrounds which can be usefull. You can load one, and then you can decide to Remove the Backgrounds you don't need, or you can also Remove all Backgrounds at Once. Once you have a background picked in scene, you can also align the Scene View Camera to it, with Align Camera, so that is gets behind as intended.
