3D Shape with Tiled Background Error On Right Face only

[arcadesindo]

Problem description

When we try to use the tiled background as the face of the 3D Shape, it was all fine, until it just happened on the Right face. Not quite sure if it was the problem of Tiled Background or 3D Shape, but I think its from the Tiled BG?

Attach a .c3p

Steps to reproduce

1. Attach Top, Left, Right, Bottom, Front, Back face
2. Try to resize the 3D Shape

Observed result

Expected result

The tiled of the Right Face should be symmetric as the Left Face have

First affected release: We've been trying this in r293.3 and also r300, but still has the same issue.

This is by design: the texture mapping of 3D shape is actually consistent, but in a way that is not ideally suited to a side view platformer. If you hide the front face and set all the side faces to the right face object and then resize the shape, you can see texture mapping works consistently in an anti-clockwise order around the sides.

You can use the Tiled Background properties to adjust the texture mapping though - the object is 180px tall and showing a 128px tiled image, so if you set the Tiled_RightFace property "Image offset X" to 52 it perfectly aligns to the top like you want.

thanks ashley, but why the right face didn't going the same like the left one when resizing?

[AshleyScirra]

As I said, it's because texture mapping works in an anticlockwise order around the faces.

so there are no ways other than changing the offset manually?
