Title: Corona Scatter
Post by: gerbilho on 2014-07-06, 12:48:24

Hi

I'm trying to make grass on a plane with corona scatter. The problem is the grass is on the wrong side of the plane, so "growing" upside down. The normals are correct, and were working well with multiscatter.

Any advice?

Have you tried to reset xform of your grass model?

I'm not sure I knw how to do that. I applyed a Xform modifier to the grass objects and nothing changed.

I solved it by flipping the normals on some planes (I'm scattering in multiple planes). But I find it odd because the exact same scene had previously a multiscatter applied and was working fine...

Not happy with the result... Grass now is growing up which is ok but the exposed parts of scatter surface look weird because their normals are inverted...
Tried reseting xform in grass objects and nothing changed.

Any more ideas? Why does multiscatter workd correctly and corona scatter with the same scene interprets things differently?
