Odd behaviour in Surface Force using Normal?

[tymc]

Hi there,

I was trying to emit particles from a hemisphere geo (bottom faces deleted) using "surface force". (like speed by surface in PF)

Maybe I had the wrong settings but although the normals of the geo seem ok, and the particles seem to be generated correctly, the vectors in which they are shot outwards seem to be wrong.

I chose "Face normals" and "Accurate" sampling but still the directions are way off (even downwards).

(see attachments)



What am I missing?
Please help!

Thanks!
