Texture deterioration in City engine

Hi,

I am trying to build a model in city engine for feature class called "Landscape" . Using texture method I render one jpg file. After rendering in city engine the texture get collapsed (ref attached snapshot). The CGA is as follows:

attr textureScaleX =100
attr textureScaleY = 100
const facadeDirectory = "assets/BrickWoodStone/"

Landscape -->
comp(f) {object.top: Landscapeface}

Landscapeface -->
setupProjection(0, scope.xy, textureScaleX, textureScaleY)
projectUV(0)
texture(facadeDirectory + "Landscape.jpg")

JPG file size is 56kb.

Kindly let me know how to resolve this issue.

Regards,

K.Jayakumar

Maybe the shape that you're trying to put the texture on is in xz instead of xy. Try this:

rotateScope(0, 90, 0)
setupProjection(0, scope.zx, '1, '1)
texture("builtin:uvtest.png")
projectUV(0)
‍‍‍‍

Using scope.zx instead of scope.xy in setupProjection() means that the u direction will correspond to the z axis, and the v direction will correspond to the x axis. The rotateScope() operation makes it so that u will go along the shape's original x axis, and v will go along the shape's original z axis. You can take out the rotateScope if you're happy with u corresponding to z and v corresponding to x.

To see the shape's scope, use the Model Hierarchy (Window -> Show Model Hierarchy -> Inspect Model -> select shape in viewport).
