Is it C4D or Hair Department?

In the attached image, the grass is below the crumpled plane instead of following the topography. C4D tag properties and the HD settings, especially gravity (0>1.5), have been adjusted many times. Nothing affects it. Larger areas with greater y contours will have v. short grass or bare areas. Any suggestions?

try selecting the polys where the grass is upside down and reversing the normals (its in the right-click menu). the normals may be pointing down instead of up.
The cow is of the bovine ilk; one end is moo, the other milk.

Thanks Rendermania. Reversing the normals didn't work. ??? Puzzled.

I see the same sort of thing, not quite as much as yours though. My guess is the splines (and therefore the grass) are being put at the center height of each 'ground' poly. Some end up below and some (try some shadows) are ending up above.

subdivide the ground and it happens a lot less.

It appears to be a hair>crumple issue. The same results occur with an open crumpled hemisphere. I emailed BGS-Group with the same question. I will post their response.

@bdjones - I will give your suggestion a try. Thanks.

Copy the terrain first. You can subdivide the terrain.1 to get smaller polygons, use Hair Department on it to get the grass and then delete the hi-poly terrain, adjust the height of the splines if necessary and you should be good to go. You may consider using several selection sets to get the patchy non uniform height and width and clumping that actual grass fields that are not golf course manicured has.

BirdTribe - thanks for the help.

How? I tried everything to break apart the splines and move them. It was a no go.

Your process was a good learning experience and there was a greater effect. The results, however, were similar after chucking the hi-poly terrain and activating the low-poly terrain. See the image.

I agree with your golf course comment. I used ColorChanger but would like to try your suggestion for "the patchy and clumping" look. I need some help here, too, since none of the selection tools seemed to work for me.
