I can import .ai files into Flash and they match.
I can import vector files from Flash into Illustrator and they match.
And the same with all other vector illustration programs. I use them all - well, most of them anyway.
The problem, as LM outlined above, is Moho is not the same vector program as the other vector programs. perhaps a good example is using electricity, it´s similar trying to get AC into DC or vice-versa.
I am very aware of all the problems with .ai files - I have been involved with most of the discussions regarding them. Please check the forums.
I´m still not sure what discussing them all again (for the 4th, 5th or is it 6th time?) will accomplish anything. (Hence I suggested LM put their explanation above on their FAQ page.)
Like I mentioned in my post above I have yet to see anybody post any .ai file animations on any Moho forums since I have been here - other than me. (Perhaps you could post a few!) So it does not seem to be an issue for 99.9% of the Moho users.
And you note your concerns regarding CMYK files and they shouldn´t be imported into Moho - yet, Moho 5.1.1 has an update specifically written for CMYK .ai files. Check the forums and I think you will find LMs explanation for that. (This has been discussed before in the forums here - hence the 5.1.1 CMYK update.)
And you will find that Moho does import the basic RGB colors (black, white, red,yellow, blue, green) very well - but try some off basic colors and you will start noticing the difference. (The Picasso graphic has lots of basic colors in it.)
You also note: "but the RGB files I export from the software I do use match well for colour".
"Match well" is not good enough for my clients. "Match perfect" are the magic words. And even if the colors matched and the shapes sucked, what good is that?
(And don´t forget the points in the Moho version - over 3,500 points in the Moho Picasso graphic. Thousands and thousands more points can mean slow to impossible animating and rendering, sometimes dragging one´s computer to a halt. One time I imported in one single .ai drawing file that Moho converted to over 50,000 points. Took about a half hour just to load in Moho!)
If you don´t use a vector drawing program or never plan to use a vector program to import .ai files into Moho then there is no need to worry about the problem Moho has importing the .ai files. (Who even uses .ai files in Moho???)
Use Moho´s drawing tools or even better, import .png image files into Moho! Moho is best suited for "cut-out" picture type animations - using raster image files.
