Bender - can't seem to center curve in a box

[TheDane]

Hi, new poster here, but have been lurking for some years - I don't play Sim4, but I use the Bender tool for texture work in other contexts.

So, I used Bender before to make this:

However, it was three years ago, so I have absolutely no recollection of how I did it - and now I need to make something similar. I've tried tampering with it, but all I can get it to do is this:

And when I try to change parameters, it reverts back to the parameters of the original image when I press 'Go', even though I chose 'Manual'.

It's driving me nuts! I can't get it to centre my curve in the box, so I gather I'm doing something wrong. Can someone help me with this? Pwease?

I suggest that you should start off with a tile that has the street in the middle of it, then bend it- that's what you original must have had

Not really, no... and as you can see from my old attempt, I managed to succeed then, somehow (still can't remember what I did). You do give me an idea worth testing, though, so thanks! I'll be sure to update if/when I succeed.

Nailed it! I put it in an all-black tile, so I had a good contrast. Then I ran it through Bender, and it was easy to remove the black background again with the magic wand in PS. The result is perfect!

Thanks again for pointing me in the right direction, and for making such a wonderful tool.
