Re: [Nuke-users] STMap produces line where right and left image edge join

[Patrick Heinen]

I'm generating the STMap with (x+0.5)/width and (y+0.5/height). It doesn't seem to be off by a pixel, as everything but that one pixel line is spot on. As for filtering, I have a case where it shouldn't filter at all as pixels are getting mapped one to one. I attached an example script that shows the issue. Thanks for your help!

When the filtering is set to cubic on the STMap I get a one pixel line at that edge, that I don't get if I ran through the transforms without an STMap. Switching the filtering to Impulse, the line disappears, but obviously everything else looks crappy. I checked the values of the STMap and the source and destination pixels seem to be correct. Has anyone had this problem before? Or has someone maybe an idea, what could cause this? Thanks and enjoy your weekend!
