Problems with renderTexture in PIXI4 - texture is not visible

[Daevid66]

Hi, I'm trying to migrate a quite large project to PIXI 4, and has managed to get most of it running fine.

I have one issue still though, and have tried to reproduce it here:

http://codepen.io/anon/pen/VmXPGa?editors=0010

What I do in the example:

1. create a container and add three graphics objects (circles)

2. create a renderTexture, and render the conatiner to it.

3. create a sprite and with the new renderTexture (this is shown correctly)

4. create a new renderTexture and render the sprite to it

5. create a new sprite with the new renderTexture

The last sprite is invisible... When looking at the data for the textures they look the same, so I guess it's the actual bitmap that is incorrect.

In my larger project I can sometimes see flickering artifacts od the texture in wrong places, indicating that the rendered texture might be shared between different sprites.

Has anyone seen anything similar?

OK, I think I get it now. I have offset the the image so that it is drawn outside the texture. Makes sense, I will solve my problem by creating a helper function that:

- gets the bounds of the target

- save parent

- create a new container, and move it to compensate for the targets position

- re-parent to previous parent

Cheers,
