If i start in 2.49 my hair is fine . but when i work in 2.5 some of the faces have the hair facing into the model (making bald spots on the out side). If I open in 2.5 a 2.49 blend with hair It looks fine no bald spots. I can not see anything different in the settings. What is making the hair go inward in 2.5 ?
Thank you
try ctrl N ( recalculate normals outside )
Thanks but the normals are ok. I can just start in 2.49 and open in 2.5 till i see what it is, there is something different in the default settings.
