Sprite not visible with orthographic camera

[nvaytet]

Adding a sprite to a scene with a PerspectiveCamera works as expected:

import pythreejs as p3

m = p3.SpriteMaterial(color='red')
s = p3.Sprite(material=m, position=(0, 0, 0))

width = 800
height = 500
camera = p3.PerspectiveCamera(position=[0.0, 0, 2], aspect=width / height)
# camera = p3.OrthographicCamera(-2, 2, -2, 2, near=-2, far=1000)
scene = p3.Scene(children=[camera, s], background="#f0f0f0")
controls = p3.OrbitControls(controlling=camera)
renderer = p3.Renderer(camera=camera,
                       scene=scene,
                       controls=[controls],
                       width=width,
                       height=height)

renderer

A red square is visible in the scene.

However, if I change the camera to the OrthographicCamera, no sprite is visible. After looking around the web, I tried playing with the scale parameter of the Sprite, making larger or smaller, but to no avail.

Thanks for any help.

Scratch that, the issue was that the top and bottom were flipped in the orthographic camera. Should have been camera = p3.OrthographicCamera(-2, 2, 2, -2, near=-2, far=1000)
