I apologize if this is in a topic that I couldn’t find, but we’re having trouble with the Stoner palette node, particularly how it interpolates the distortion between bezier control columns and rows. If we use a smooth bezier control row both above and below an image we want to distort, the image in between interpolates in a “linear” fashion, not distorting according to the control lattice. We get numerous “peaks” in the image, which is especially noticeable in small legal text. This doesn’t happen with other software, particularly with MadMapper and AfterEffects, which have similar approaches, but higher quality results.

It seems to be a problem inside the stoner/ui/controls/convert5 SOP, shown here, The problem is clear when you see the posGrid being “converted”.
Hi Markus, thanks for the quick reply. @ctedin is on my team. This is live at an install currently and just looks awful. I’m flying to California tomorrow to see what I can do to fix this. if you have any insight, please let me know what I can try.
Thanks!

Hey @m1interactive1,
what build do you currently have installed?
The problem is in how the inside handles of the bezier surface are being transformed. I think i can get this fixed quickly.
cheers

Currently on 2023.11170 experimental, but we can use whatever you recommend. Overall the project is pretty simple to rebuild if we need to.
Hi @m1interactive1 and @ctedin
I think I fixed it for most cases - still see an issue when selecting multiple points and moving the connected handles. Moving multiple points at once though seems to be correct now.
Unfortunately, you will have to setup the warp again.

This is better, but there is an issue still. The edge bezier controls don’t warp the image consistently. The interpolation is still not flowing along the curves.
Hi @ctedin,
Ah - I see it - the interpolation in between handles is broken. I’ll work on this.
cheers

Hi @ctedin,
attached a version were the inner weights are updated to what I believe is correct. Sorry - the whole bezier surface thing is a bit funny - the more I’m happy you are pointing this all out!

So far, looking pretty good. I can’t fully test because it’s opening into 2023.11170. The handles aren’t visible to adjust the bezier curves.
The latest looks like it’s using a newer experimental build that’s not on the website.
Ah - really sorry @ctedin,
strange that the handles are missing though… Can you try attached - went back a few versions.
