proxy objects

[cristoforo]

I am trying to figure out how to use proxy objects. I have a group of trees already in place. First of all....should I start with the group of trees already in place like that, or just create one tree and proxy it right away...then proxy in the other trees? At that point, can I scale, rotate, change seed value, etc....or will all the trees be the same. I, instead, created a proxy of the group of trees. Though, the proxied trees take the color of the porxy object. The online manual says to create a sub-object material and apply to material ID's. This worked fine proxying out one tree.....but not with the group of trees. Can someone explain the correct procedure? Thanks.

i keep a library of proxied trees. so for a scene i will create a proxie which ill load into my scene then just instance it around would be good if someone could clarify if it might save more memory if you created a forest of trees then attached them all into 1 object then proxied the entire forest as 1 object.

That would be a huggggee vrmesh file though, wouldn't it? The vray proxy files are already bloated compared to their original 3ds max sizes. I assume instancing several proxies a bunch of times would be much faster, and more memory efficient too.

While on the subject of proxies, does v-ray's camera motion blur not work with them? I just turned it on and test-rendered a scene, but the proxied objects rendered without any blur.

with trees i do it like this:
- select the tree you want to proxy
- if the trees is made of different element, convert it in one mesh
- max should make a sub mat for you, save that to a mat lib, you need it later
- make sure they are all vray mats, and depending on what tree you use, you need to check the opacity maps for leaves.
- convert your mesh to a vraymesh and save it to a location
- open your scene where you want your trees in.
- insert your vraymesh
- apply the saved map to it.
- in your case I should use the clone and align tool in max and instance all the trees (or dummy) you allready placed.
- delete the old trees or dummys
- render and enjoy your trees
this usually works great for me!

I guess I must be doing something wrong with proxy. When I proxy a tree into a scene it takes 2 or three times longer to render than the original tree file. Why is that?

Does it only help render time if there are a lot of trees?

Also, DR doesn't appear to work with proxy objects in 1.47.03. At least on my computers.

I've requested the new build with improved DR several times but I am just being ignored, I guess. Who's butt do I kiss to get the new build.

TRGraphics:
Proxys render using dynamic memory as they are a dynamic mesh as such. And therefore tend to take longer. But by using the dynamic option you can render much larger scenes.
So basically if you only have a simple scene with a tree or 2 and you currently dont have any memory problems then i suggest you dont use proxys.
Also i wouldnt expect the render to be 2-3 times longer, that seem rather extreme IMO
