Hello. How to create script buttons in the bottom panel on Windows 10? Very sorry for my terrible english

Hi artyomlekos, the ones you show there are from Max's CustomUI extension which you can get here:

You can also edit the files that make up the UI, the bottom bar comes from the file CommandBar.htm inside the \ui sub-folder inside MoI's main install folder.

Did everything as per instructions:
1) replaced the CommandBar.htm file in the ui folder
2) extracted customui folder to ui folder

I run the program, an error appears.

After clicking ok, the program starts, but the buttons do not appear.

Hi artyomlekos, that's an error that will appear if you're using an old version of MoI. Make sure you're running either the final v3 release, or the current v4 beta.

You can get the final v3 release by putting in your license key at http://moi3d.com/reinstall.htm or the v4 beta at http://moi3d.com/beta.htm .
