I haven't actually tried it yet, but I love the idea of running a little bit of mel from the UI. It will make it so much easier when running those little snippets looped code that are too specific to make a permanent script from. Nice one matt.

Would make quick work of wiring up many objects to a single binaryproxy, or even many binaryproxies. http://www.technolumiere.com/software/multitudeManager.html yep. also on the connecting-lots-things side, i'm using multitude manager more and more. handy script by andrew chapman that lets you set attrs, select stuff, do lots of repetitive things with a minimum of fuss, and build a nice preset library as you go.

Just type optionVar -iv "MIP_SHD_EXPOSE" 1 save prefs, restart maya, shaders are now all there, even placed in correct shader categories. btw, had to unhide the mip shaders (AGAIN) on 2009, noticed the customNodeClass mel uses an optionvar now, so no mel hacking required.

That's a lot of polys. I'm amazed. You can hook up the mip_binaryproxy after duplicating your proxy objects. This would be best done using some mel to loop through your objects, since there are so many. So, you would select all your proxy objects and then enter these 2 lines in the script editor. (mipBP is the name of my existing mip_binaryproxy node, so change this to suite your scene) string $sel[] = `ls -sl`; for($s in $sel) connectAttr -f mipBP.outValue ($s+".miGeoShader"); Wow!

Managed to render 18 billion (18000 objects x 1 million polys), but it can be done more (seems almost infinite). Render time is super fast, at low settings final gather and render completed in 20 seconds. My question is this, since I am not so skilled in node connection: can I first copy proxy objects (for example cube) and AFTER that connect them all at once to mip_binaryproxy node? Here are images of proxy test (this is sample tree from archmodels) http://www.shrani.si/f/2l/99/44PFVibi/proxy-test-18g-poligonov.jpg http://www.shrani.si/f/17/Xj/4oKsMwZM/proxy-test-18g-poligonov.jpg I made test with your technique and it works great.

I've noticed that when you create an object with multi textures on it, you must create a default set by selecting one of the Component ( face, edge, or vertex, etc...) without the set you get a black render with nothing! You can also export multi objects at once, say you have in the scene a lot of objects a cube, a sphere, a torus, etc... so select all the faces for the cube and create a set, do your UV, apply different textures .. Do the same things with the others objects, so the idea is: each object must have a set. Finally combine all the objects, delete the history and freeze the transformations and export as Render Proxy [Assembly] then put the combined object in to the layer and make it invisible or just hid it the rest is to load the .mi file in a cube, instance many times you want until you rich the limit! best regards /rachid Yes I've instanced 2500 objects with the volleyball and the clay, I can go up, but 2500 just to answer to this question posted here:

In the past I have had some problems with instancing and mentalray, resulting in very slow scene translation at render time. I think these bugs were fixed in maya 2008, but I have been cautious about using them still. And I have done only minimal testing of instances and mip_binaryproxy together. If you do some tests I would be pleased if you would drop back and let us know your experiences. Hi rachid, you can use instance if you prefer.

I know that copy eat a lot of memory ! So what is the best way, Instance or Parent? or are you using parent just to get different Shader? best regards /rachid As always, nice work david
