VRay Scatter for Maya

[stezza]

Usually we use MASH for proxy plants distribution but there is a big issue.
We have a building all signed off rendered using meter scale for real world light calculations.
But now the client wants an environment lots of grass plants ect.
We used MASH to create a ground section but MASH only works in cm so bringing it in to a meter scale is causing issues with everything exploding.

How do others manage this?

What do you want?
VRay scatter!
When do you want it?
NOW!

Everything in Maya should always be left in centimeters to avoid any complications and rescale to meters if doing sims . Better to know all steps involved in the project and think many steps ahead . I saw your Area post Stezza, now it gets complicated. Maybe someone has a simple solution but I would start by calculating all the lights to centimeters.

Yeah I get you, it's just in this case terrain was never going to be part of the job and the render lighting was all signed off so we couldn't risk changing it.
But I think I have fixed the issue, just done a test and seemed to work in the cloud.

Using the main scene in meters, change to cm.
Then create all your MASH proxys grass plants trees.
Make sure nothing is selected in the MASH network and switch back to Meters, send to render.
When opening the scene again you just have to switch back to cm and adjust the MASH distributions by adding an extra 1 to update it, then back to M again. phew!

PS. I use the Malcolm341 Mega pack scripts and there is a nice quick switch to cm>m

Yes Malcolm scripts are pretty handy, I m happy for you that your file is back on track. I was concerned about the scale on the shaders too like round corners Vray dirt and displacement would need readjusting to centimeters. Press on.

maya desperately needs a proper scatter tool and mash isn't it. I pray that vray scatter makes its way to maya soon.
