Plants in interior archviz
show user profile  mike_renouf
How do you generally put complex geometry like plants into an interior scene without killing render times? I'm using mentalray.

I've reduced the final gather quality of the foliage geometry to 0.5. But there are a bunch of area lights in the scene and they're not liking all that foliage. What's the accepted method? - Render plants against the same scene with matte shadow material on it and composite in post?

Cheers
Mike

In Vray we use proxies.

Am sure there is similar option in MR.

Awesome - just did a test with a chandelier and my slow desktop machine burned through a scene with about 2500 instances in about a minute flat.

Thanks for the help Girish :)

Instances in finalRender works perfect for plants, also. But for better results usually try to add plants in Photoshop.

So.. A proxy... I've heard this term a few times, and I think I know what it is, but what exactly is it?

xref.. No, I'm not.. Please enlighten me.. I am assuming it is a way to scatter objects around a scene and render only one of those objects but have them placed everywhere...

How does it work though? Am I close with my brief description?

Well from my limited knowledge, and someone may correct me.

So you import an object and by making it a proxy it basically locates the object in its own file outwith the current one and basically just brings it back properly for rendering purposes, so basically referencing the file from elsewhere rather than in the scene itself.

So because the object itself isnt actually in the scene you can put in loads of them and for example your file size wont go up nearly as much as if you had imported then directly.

That make any more sense?

yes, but if the object isn't in the scene how do proper lighting conditions get created onto the object?

Because it brings it back in for rendering purposes, so all lighting etc is exactly the same had it be simply imported into the scene. Its just referencing it from another file rather than the same file.
