Hi guys:
i want import AI file into HOudini ，but an error occured !
It says can't decode byte,invalid start byte!
the snap img is in the attachment,hope you check that out and tell me the answer!

Yeah, you'll have that. If you don't know, most 3D packages barely support AI files at all. To use them you need to open them up in Illustrator and save them out using the legacy format of AI8. Also you must outline all fonts and no gradient fills are supported.

The problem, most likely, is your AI file.

Convert and try again.
