Michael Emo Posted March 21, 2007 Share Posted March 21, 2007 Hi All, Using Max9. I have a question about modeling this object. I need to model an iron design for a balcony. See attached. How would you model this so that it doesn't kill the model rendering time? I have about 30+ balconies on this huge building, and I can imagine this is going to seriously affect rendering time. It's such a small detail as well, so I'm not sure how it's really going to show up at 100+ft wide-angle camera view. Any suggestions would be greatly appreciated. Thanks, Michael Link to comment Share on other sites More sharing options...
blade911 Posted March 21, 2007 Share Posted March 21, 2007 i had a similar issue once.. this is wat i did. leave them as single lines in cad. n in max line renderin options enable in renderer n give it radial thickness or wats required. enabling in viewport gave me trouble. depends on ur system. or u cud make one balcony as a block and creat proxies if ur usin vray? not sure about this but worth a try. cheers Link to comment Share on other sites More sharing options...
guitarmunkee Posted March 21, 2007 Share Posted March 21, 2007 How about making that design in photoshop, throwing it on a plane with a alpha channel so that only the design shows in the render? Would that help? Link to comment Share on other sites More sharing options...
Michael Emo Posted March 21, 2007 Author Share Posted March 21, 2007 I am using VRay. Is proxies difficult? I'm just getting my feet wet on VRay. So if I draw it in CAD....which it already is, can I just bring those lines into max, or do I first need to convert them to Polylines in CAD? I will do post production in Photoshop and have thought about that perhaps, by rendering the piece by itself (all other objects turned off) and then combine in photoshop but figured the lighting wouldn't look right. Then again, it's a very small black object, so probably won't show much lighting effect? guitarmunkee...I'm not sure how mean? Render one copy of it in Max on the proper plane, then copy/scale layer? Thanks for the prompt reply guys! Link to comment Share on other sites More sharing options...
kippu Posted March 21, 2007 Share Posted March 21, 2007 if you draw it in cad .. you can import them as splines and then give them thickness in max ...modelling is a better option because the alpha maps wont work at some angles... Link to comment Share on other sites More sharing options...
Michael Emo Posted March 21, 2007 Author Share Posted March 21, 2007 Thanks Kippu! I love this forum! I going to try it right now Michael Link to comment Share on other sites More sharing options...
only3d Posted March 21, 2007 Share Posted March 21, 2007 if ur into poly counting (which u should if ur worried about rendering times) u could actually do the same in max. i mean instead of drawing in acad and then giving it thickness in max u could do it all in max from the get go. that assures u better smoothing with less polys. btw im not sure the alpha idea is too bad.. did a really complicated element of same nature and worked brilliant. not sure about cutting render time though most definitly cutting alot on the poly count! (easier on your workflow) good luck anyways Link to comment Share on other sites More sharing options...
batteryoperatedlettuce Posted March 21, 2007 Share Posted March 21, 2007 Talking of poly count. I have a scene I'm currently working on, which contains 1,600,000 polys. I took the bulk of the stuff out to do a test render, leaving 4000 polys and the draft render time dropped from 15 minutes and 17 seconds to 15 minutes and 12 seconds I really don't understand. Poly count seems to have the least effect in renderings. Lighting and materials seem to soak up far more render time. I'd say just model the things and proxy them or export them to another file until you're ready to render. Lots of polys seem to put a strain on my graphics card, but that's about it.

richmondlu Posted March 21, 2007 Share Posted March 21, 2007 lighting, reflections, shadows, transparent objects make up most of the math that is why you should renderin in layers. Link to comment Share on other sites More sharing options...
AJLynn Posted March 21, 2007 Share Posted March 21, 2007 Ploy count doesn't matter to Vray, so long as you have enough RAM. And Vray cooperates well with instancing, so if you make one piece that's high poly, export Vray proxy and then instance the Vray proxy reference for the repetition you're not going to lose performance in Max or in Vray.

cloaked_spectre Posted March 21, 2007 Share Posted March 21, 2007 if you have access to autocad.....create the shape extrusion once, then make into a block, then rect. array the pattern.....then dump into max as instances....file size greatly reduced, plus you get the realistic shadows, etc. as opposed to an image/material applied onto a plane.....I am getting fast render times using this technique....25 min on a large presentation quality site and building renderings.....

mskin Posted March 21, 2007 Share Posted March 21, 2007 why not create the line work and then use the sweep modifier? Link to comment Share on other sites More sharing options...
manta Posted March 21, 2007 Share Posted March 21, 2007 The geomerty is pretty simple, just model one balcony, and if they are all the same, export it as a proxie mesh, and instance it 30 times... Link to comment Share on other sites More sharing options...
