Kantan Mapper Free Form Shape Bug

Bugs
1

Hey Touchdesigners,

I did a projection mapping setup last night and it went okay BUT kantan mapper tool in the palette was super frustrating because it seemed after drawing a few shapes it wouldn’t let me close the free form. The solution I found was to save the mapping file, close the software open it, load it again and then draw one shape and redo this over and over again, I had about 30 shapes…

Anyone have advice on this issue? see below for the error it’s throwing as well.

Thanks!

Hi @Smelvin0,

sorry for your trouble there. Haven’t seen this in a while. Can you share:

  • TouchDesigner Build you were using
  • OS
  • Hardware details including Videocard
  • where you dropping lots of frames
  • could you share the kantan project here

Generally, if you get stuck in the freeform shape, clicking on either the “Select Shape” or “Select Keys” tool should close the shape for you

Hey there,

Here’s the info.

  • touchdesigner Build 2023.11880 but I updated to 2023.12000 and still had the same issue.
  • Windows 11 Pro version 23H2
  • AMD Ryzen 7950x3d, Geforce RTX 3090 (Ventus trio), Kingston KF560C30-32 DDR5 (64gb) (let me know if you need any other hardware info)
  • Nope, I started a brand new project to do the mapping so that I could bring it over to the intensive project after, thought that might be the issue but it still remained.
  • 20241104_KantanMapperBugFolder.zip (1.0 MB)

Clicking on the mouse tools worked for a bit but it seemed after a certain amount of shapes drawn it bugged out.

Right now as I was prepping the file to upload I tried it out and the first one or two new shapes drawn when re-launching it from desktop is no problem but the second or third generally won’t let me close it. So make sure to try a few to replicate the issue.

Thanks for getting back to me! Let me know if there’s any other info you need.

Hi @Smelvin0,

thank you - this was perfectly reproducible. I hope to have identified the proper issue.
There was a lookup into a table by row-number instead of row-name causing it to be impossible to identify the shape to be closed.

Attached a fixed KantanMapper plus your file with the fix included.

wow thank you so much! Very quick!

Does this mean that it will be updated in the palette in the next release?

Is there a way to replace the default tox’s to have it automatically load this updated one?

EDIT: Above question was very easy to do myself if anyone else is having the issue, on windows just place the tox overwriting (if you want) here C:\Program Files\Derivative\TouchDesigner.2023.12000\Samples\Palette\Mapping
