MASH distribution on mesh with offset

Hello there,

 

I have a small problem, but it is a problem. I want to create a grass carpet using MASH and PaintFX. When I distribute the grass on a floor_mesh there is a slight offset (as you can see on the pic) and I have no clue where this comes from.

 

Maybe someone knows where this comes from?!

 

Regards,

Sascha

Hi!

Please upload the scene-file.

(A scene can't be checked without the scene and there are too many reasons possible for this result.)

Of course. Attached a scene file.

 

Can't upload a file here. Don't know why, but here is a link:

Thank you.

Hi!

 

The original mesh "grassBent1Main" is not at scene origin.

Just move this mesh to scene center.

I have the same problem here, but your hint did not solve the problem.
Zero transformations, no history, just plain, clean geometry. Wherever I place it, the Mash points are not distributet on the surface.
And yes, I did connect the mesh into the input mesh.

It is annoying.

Hi!

 

Your source meshes are also clearly offset, use Bake Pivot to correct this.

Hi mspeer,

 

I can not see what you mean. My source

Unbenannt-1.jpg

and my target meshes as well have no offset at all (freeze transormation - maybe thats what you meant by bake pivot).
Not even one mesh in the scene has transformation/rotation/scale values.
No history, no nothing.

Do I misunderstand something?

Hi!

Move the object to the center of the scene and then check again the values.

This is not the center of the scene, the mesh is offset from the center and this offset will be applied to your objects in MASH too.
Also Bake Pivot is not the same as Freeze Transformation, please check the Maya online help.

Hi there,

so center of the scene, new created plane.
No offset at all but still the same problem.

I am lost here.

Hi!

 

Check your object "pasted__leaf02", it shows 0 0 0 for translate, but it's clearly not at the center of the scene.

This is a huge offset.

If you've centered and froze transformations and all of that and it still doesn't work make sure you are in default cm units. I had this issue and changed it back to cm from inches and it worked perfect.
