Hardcore hair question ** paypal reward offered **

[user_deleted]

just kidding. no reward.

here's the question:
I have a hair setup that comes from Maya 7.0.1
I'm opening it in maya 2009 x64, and it appears wrong. (some hairs standing on end, all hairs less wavy than in maya7)

I've checked scene units, frame rate, and other usual suspects but everything is the same.

The only clue is:
When I select my hairSystem node in maya 2009, the script editor says:
// Error: No object matches name: |hairSystem1|hairSystemShape1.attractionScale[-1].attractionScale_Interp
This doesn't happen of course in maya7.
Any ideas?

Thanks!

hmm.... a negative index is not a very good sign.

If this is a maya ascii file you could chek out the file and try to rename the connecion. Theres no tmuch you can do in a binaryfile.

PS: if you have a maya support contract it means your eligible to all maya versions, which means you could open it in all successive mayas and see if it indeed actually would work out better if you do not try to jump too many versions in one go. After all maya 7 is a old.

You could try this. Save a preset on the current hair system shape. Then delete the entire hair system, create a new one and apply the preset. Maybe will help.

Alias changed the hair attraction settings between version 7 and 8 (or was it 2008?...) anyway, the start curve attract attribute is probably what you are looking for to correct your problem. Either set it to zero so it doesn't conflict, or perhaps you could just use the start curve attract feature rather than the older attraction setting. Good luck!

If this tip helps I want my reward!

You can pay me in coffee beans instead of cash if you prefer... =D

8.5 was the last version number.

Thanks a lot guys. =) After some investigating I went back to the earliest work in progress files of that hair setup in m7, and found that there was a bug back then affecting the start curves. Even on faces with proper uvs, hair would sometimes stick out sideways (parallel to the polygon) rather  than along the normal.

Rather than carry around a buggy setup from a buggy version of hair plugin, I decided to redo the hair in 2009...
brute force solution but more peace of mind.
