Posted: April 25, 2007 Post subject: Ecosystem memory
I'm wondering..... If you paint an ecosystem (local material not global system) and you replace the mesh on which it was created, is there a way to get your ecosystem back. For instance, I painted a parking lot with cars (instead of figuring out a proper density function), when I reexported the parking lot mesh out of Viz, the program asked me to update, I did, and lost the 1800 cars or so that I placed, with no way to get them back except to waste the time to do it over.
However if the changes you've made to the mesh have altered the height of an area under an instance this won't alter its height for you so your cars might end up floating in the air or burried in the tarmac. _________________ Cheers Mark
>>Mabey you can load the new object on top of the old object and apply a completely transparent material to the underlying material ?
This would work in max, but in vue....who knows. Razz<<
I think that might be your answer. Keep the old object with the ecosystem, but then perhaps apply or tell the underlying/old object material to be either transparent or not render. I think there's an option to hide the material but keep the shadow, or turn off the shadow, or both. Or as you said, simply make it 100% transparent.
Then put the new object in the exact same position.
Thanks for the ideas. I had not looked at the forum for a few days so I created a cheat. What I did was create an object that I will never use or see. I apply the ecosystem material to that. So as long as I never delete it, then I always have my ecosystem. That was the cheat, but I like the idea of a Python script like Marc set me up with.
