The Tile Node seems to allow you to tile an input image ONLY in positive directions: up and right.

My goal is to expand the canvas size in all direction, like in the following image, and fill the new area with a seamless tile (mirror of the original image).




So I tried to do to a custom setup, with the composite node, but the “image wrap” parameter seems to be broken. It doesn't seem to mirror the image. Please have a look at the project file

see attached,
append a crop after the BG color.

definitely a bug with color and/or composite though.
seems to work OK with a composite via vops, if it doesn't crash.

WOW thanks a lot for providing the vop setup to do same the effect.
That's very good learning material!


Also, nice find about the “crop” fix to append before the composite node.
But it doesn't really make sense to me why that crop node fixes the mirror wrapping bug of the composite.

How did you come up with this workaround?

cheers


will submit scene to SESI support and update with their response

I think it was a suggested workaround for an exr bug ages ago, something about ‘window’ size vs display size… window size not being defined correctly, which crop fixes by seting it to the display size (by default).

Append a window cop to the BG color, you can see the blue window frame is busted.
Insert a crop (or border) cop between color and window, the blue frame should be corrected.
