help with converting maya splines into Geo, i'm really frustrated . ( Solved )

Vamptacus

alright . this is my first post here so hello everyone now let's talk about my problem which has been bugging me since 5 hours ago ..

i'm watching a tutorial on creating hair cards and things were going smoothly till i reached the part when i had to convert my splines into geometry using a free script called simple pipe .. but guess what.. the script isn't working .. the website that you can download the script also isn't working and now i've been searching through the web to find another way of converting them for the past 5 hrs with no luck .. i'm crying here please somebody offer me a solution ..

btw i get this error when trying to the run the script

Warning: Line 41.30 : Redeclaration of variable "$circle" shadows previous declaration at line 38. Previous value will be overwritten by explicit initializer. //

and this is the link for it https://www.highend3d.com/maya/script/simple-pipe-for-maya

i also checked a video or two on cable which seems to be what i need but from what i saw the scale of it doesn't let you make it to thin which isn't what i want ... if some1 worked with it and you can then please tell me so i can get it

Why do you need geo? Most render engines are able to render splines.

well i'm trying to follow the tutorial for creating hair cards for game use which at this point he turns the splines into geo using the script i mentioned ..

it's my first time going for hair cards that's why i'm trying to follow the tutorial, i would've preferred using zbrush fibermesh but i'm not if it's as good as doing it with xgen.

Arnold can render the hair directly from the xgen descriptions - it's much, much faster than converting to geometry

If you really want it as geometry you can use xgen with alembic export to do that (you'll have to check docs cos they move the button every release)

Note these are just links I found, I haven't tried it personally,interested in hearing how it goes.

thanks i appreciate the help, but my problem did get solved, i showed the script to a friend who knew scripting and apparently there was a single line missing from the end of the script which now works perfectly

thank you, actually the tutorial andrew talks about in the first link is what i'm currently following, there are problems i'm having tho which is why i'm planing on asking for help here again, thanks for replying.

Do you mind sharing your solution? What was the missing line of code? It would help othes too...

I don't know if xgen splines are the same as a curve (or maybe you can convert them to a curve), but there is a tool in bonus tools called curve to ribbon mesh which would be nice because it gives some handy options for the resulting mesh.

wow i can't believe i forgot to mention that .. sorry. take a look at the last line, u just have to add simplepipe () ; and press execute all ( if that's what it's called )

if you don't have the plugin i can upload it for you, it is a free plugin after all.

Thank you!! I appreciate it I just used the xgen conversion instead earlier since that works too but nice to know i can use simple pipe again.

right now, I had a same problem with simplepipe in maya 2022 and I fixed it by putting SimplePipe; at the end of the file and it works like a charm. you have to put SimplePipe; without () and PascalCase naming convention.

In maya 2022 just use sweep.
