Yeah, you need to check the pivot point is at the base, or slightly above it. There are some great pivot placers on http://www.scriptspot.com if you want to automate this, but it shouldn’t be necessary with a single blade.

The other problem you might have is double faces. To check, convert your plane to an edit mesh and delete the polys after selecting them individually. If you have any double faces a poly will remain after deletion. This shouldn’t really be the case with a plane though as this is always single sided, but is a common problem with extruded splines, as the extrude modifier has cap start AND end.

I hope that helps!

Thanks for the tutorial. This is great and is a huge help!!!

However, I am new to modeling in 3ds and I can not seem to get the blades to scatter properly on the plane. Everytime I use scatter, the planes either flip in a alternate axis, or I work that out but the center of the blade is centered within the plane (half of the blade is above and the other is below). I can not for the life of me figure what I am doing wrong. I feel that is has something to with since the blades are made of planes, and the axis point is located in the center of the plane, the scatter is using this a reference.

I would love to know how to scatter the grass blades so that the bottom of the blade is the reference point and stays on top of the distribution plane.

Any help would be appreciated!!

LOL. I assume you’re refering to DiizGroup’s comments James? I think that was to do with the building in this image and animation; not the grass. ;-)

wow who cares who gets credit for what.. quit being babies about it.. its a tutorial to teach people not a place to show off how great you are at connection vertices together.. seriously grow up.. credit lol.. u got to be kidding please put my name its my piece of grass i can tell because my vertices are different then yours there better man they have sharper dots then your polygons so gimme credit man lol.. why dont you concentrate on something like work or another tutorial do something productive instead of whining about a piece of grass that may or may not be modeled by you
