i created some road objects, added 4 grass planes and did a testrender ... all looks fine.

then i lower the camera and suddenly the grass goes crazy ... what is this circular shape of the grass planes. the planes are not grouped. it does not happen to the other road objects ... i have no idea what this is. oh ... the more the camera is lowered the smaller the circle radius is.

What material (grass) is that? And what is the mapping method for this material? Maybe a change in that mapping method changes this behavior.

the grass material is grass-generator from the stones and groundcover package ... the mapping is world standard ... and i found that i also cannot add eco-system and populate.

so i saved the road stuff as an object, created a new scene, added 4 grass planes ... and now it works?!?

i guess somehow the file went bad ... it's been a long day at the office :-)

Hmm, That's very odd.  Looks like some sort of camera distortion occured.  One question.  Why are you creating 4 grass plane objects instead of a single grass plane object?  Is it just to allow for different eco's on each of the planes?  Nice looking grass by the way.

i created 4 planes because the road level is lower but come to think of it i could create one plane and add a transparency or alpha mask i guess ...

and yes, the grass is very nice! thank the creator of stones-and-groundcover :-)

Looks like you're limiting the camera's view range for the grass plane.

but how would i be able to do that? i have not found an option for that to set.

I've seen it somewhere.  I'll have to look for it.  Is it Vue 7 Infinite you have?

Did you happen to use a cut-off filter for your lighting?  If the light was conic in shape for instance.  Maybe too late now, but did the grass plane have any cut-off in the OpenGL window before rendering?

its vue7 xStream which is the same as Inf i think.

i just used the default athmosphere scene added the objects and rendered. did not alter anything.

the open-gl worked fine. i actually found where i could set the clipping for open-gl.

i think it must have been some bug or bad state of the system as it worked after restarting.

sometimes i get the feeling that vue has a personality of its own. after a long day without breaks it likes to do stupid stuff more often ... :-)
