Deform a quad image within the boundary of an object using relative vertices with the object.
Hi Mikal, I know this was a while ago now but I am revisiting this and trying to overcome this same issue.
I can try and send over an example showing the issue but to describe again:
It is a single PNG image that is transparent right to the edges of the image with only some non-alpha parts within the image. The non-alpha areas are a solid colour (red) which is what is then seen as a thin border of the whole image (the 4 sides).
Again it only happens when using tri or bilinear sampling.
Hope you can help.
Hi, sure upload a link to the project (I use sendgb.com to share files, but whatever works for you.)
In general I use 3DShape or 3DObject to do what I used to want to do with this effect these days.
Hi Mikal,
Thank you for looking into this for me, much appriciated.
Please find the example file.

I took at look at this, but don't see an obvious answer, I imagine there is an issue with the transformation when the UVs transition at the border and the bilinear tries to blend across the boundary.
That's a real shame, but thank you for taking a look.
Its perfect for my use if it wasn't for this small issue and frustratingly I cant really find another way/addon to get same behaviour. :(
I also noticed that setting "Downscaling to Low" removes the issue but again this then results in "blocky edges".
