Making grass. Vray fur or VR mesh?

[loco]

I need to make a big cg lawn. The camera will be traveling over a lawn at about knee height. Would you recommend using vray fur or making a patch of grass that will be generated with VRmesh? Any thoughts to the pros and cons of each method? Perhaps another method? Thanks

how are you generating grass with vrmesh?

I've converted a patch of grass from maya paint fx to polys. They are about 20,000 faces.

ha, i though as much. It just sounded odd.

I would probably do it with vray fur or do a seperate pass of the grass with max hair and fur and comp it on top.

depends on how real the grass should be. Vray fur will be pretty slow and it doesn't really look like grass. But with relatively fast movement you will not notice it of course

The motion of the camera will be very slow. A camera drift over 3secs.

I've done grass converting the hair & fur in Max to geometry, then exporting this as a vrmesh. Rendered pretty quickly... the vrmesh ended up being over 350 megs.

Depending on how much the ground plane bends, you might be able to get away with making a 1'x1' patch of grass as a vrmesh, then spread this out over the ground plane.

that s a gr8 idea imo!

Funny thing, though... I didn't even think of that until I replied to this message - I've been making large patches of grass doing the hair - vrmesh for a while... I'll have to give this a shot sometime this week!
