Rocks

[glorybound]

Hi,

I have a project that requires a large amount of 10" boulders to be placed over a rather large area. I tried displacement, but the clients wants the rocks to gradually get smaller towards the outside parameters. Any tips? Has anybody come across this? It is a house on a hill with boulder landscape.

Any help would be greatly appreciated.

Particle flow with the scale driven by grayscale values - you could use a gradient so they get gradually smaller. If you're doing a still you could also use an animated scale operator and make sure that the inner boulders are born before the outer ones so you can collapse it at a point where you have the gradual difference where you want it.

PFlow

Way over my head . Is it worth be getting involved with it? Will I get good results and is it a pretty simple process?

You can try Groundwiz. We use it for trees and such and you can use VRAY proxies. You can also paint the rocks where you want them as well as random scale and rotation. For a single license its $160 and for license + unlimited render its $495. It also can help with shading mountains and the like by allow textures to change based on height and angle, kind of like Vue.

There are other planter type scripts as well I believe.

Groundwiz

I looked into Groundwiz awhile back and I remember it not playing well with v-ray. I might just use geometry.

If you want to avoid particle flow you can draw a few meshes being the volumes to put a certain size boulder in, then use these as emitter for a PArray or as distribution object for a Scatter.

Just paint them in the way you want, there isa built in rock and you could always use an replacer script to change these rocks out for proxies.

I have used that, but it seemed that my scenes have to many poly's for it to be effective. I'll check it out again... thanks for the reminder. I ended up placing each stone and using the glue utility. It worked great, if I can only render it now.
