Cesar R Posted May 27, 2003 Share Posted May 27, 2003 where can I find a tutorial on setting up radiosity rendering in LW for exteriors and interiors. So far.... do I always have to create a white dome for my sky? (interior/exterior) what about sun light, what should I use to simulate that?

dwright Posted May 28, 2003 Share Posted May 28, 2003 I will look for something... regarding sun light; you can use the sky tracer 2 (env plug) and discard clouds. ST will generate and control sunlight. Link to comment Share on other sites More sharing options...
Cesar R Posted May 28, 2003 Author Share Posted May 28, 2003 ok thanks for your help. I hope you can find something that will help me Link to comment Share on other sites More sharing options...

Cesar R Posted May 28, 2003 Author Share Posted May 28, 2003 david, is lightwave the only highend CG program for MAC aside from Maya? = also how do you like LW compared to MAX (if you had the oportunity to use MAx that is) Link to comment Share on other sites More sharing options...
dwright Posted May 29, 2003 Share Posted May 29, 2003 mmm you are putting me in a difficult spot . Cinema 4D is also mac based and so far it looks amazing for Viz work. Max is clearly a great tool, but it does not well on polygon count, in other words, handling huge amounts of data, it collapses, both renderer and layout wit our typical large-scale projects. Maya, also great for character animators, but its modeling workflow is way slow for our archviz modeling and time frame constraints. And its rendering engine, not including mental ray, is WAY slow and not good. So far, Cinema 4D and Lightwave are the tools we like (we do not use C4D yet, just played with demos) clearly this is just my opinion. Max is used everywhere and great results come from it. We simply get nervous when using it on real projects. Link to comment Share on other sites More sharing options...

xgarcia Posted May 29, 2003 Share Posted May 29, 2003 David, Could you walk us through your work-flow if you don't mind. Do you begin modelling from scratch in Lightwave or do you import from 3D from AutoCAD? I am interested in learning more about Lightwave since you speak so highly of it. I have a fiend here at the university who swears by it, but has I first learned AutoCAD, then formZ, then Viz/Maz, then Lightscape, alas Lightwave seems weird to me. Thanks.

Cesar R Posted May 29, 2003 Author Share Posted May 29, 2003 I second Javier.. if you dont mind. also you were going to post an image of the stadium before it went into PS. Well, I am starting to like LW alot better than MAX to be honest. or maybe it has to do with the fact that i am workin on a mac? I love macs by the way, im never going back to a pc !!! ok wrong thread Link to comment Share on other sites More sharing options...
dwright Posted May 29, 2003 Share Posted May 29, 2003 We import 2D from CAD via dxf/3ds into Modeler and then we work from there. If 3D geometry was previously or partially done in CAD by our client, then we carefully un-ensemble the object in CAD and export to 3ds by small layers, for then into modeler. I don't think I spoke highly of LW, I am not a fanatic, we clearly use it and have great results from it. Currently we are studding the possibility to start doing projects with C4D, but not 100%, nor we plan to switch, but we are worried that LW recent update history has been very slow. Regarding our stadium, as soon as I get time will post something. Regarding Mac Vs. PC's.. mmm I will not go there Link to comment Share on other sites More sharing options...
Cesar R Posted May 29, 2003 Author Share Posted May 29, 2003 haha, well thanks for the insight. let me as you something. when i model several object for example cube and ball and another box, in the same layer they become ONE object correct? even if there are far away? or am I doing something wrong?

dwright Posted May 29, 2003 Share Posted May 29, 2003 yes. I do not recommend to bring LW objects with sep. layers into LW... mainly for large projects. Leave Layers for modeling purposes. Link to comment Share on other sites More sharing options...
ingo Posted May 30, 2003 Share Posted May 30, 2003 In addition to David's answer your objects on the same layer can be textured different. I use different layers for excluding lights for example. But i must admit i do my modelling in FormZ and export this into Lightwaves modeller, and add some things that are easier to make in LW. And although the guys at Newtek have now some rough times i love Lightwave, just wait till their new developement team keeps up pace. The good thing is you dont have to pay much for LW update And the Mac via, whats the other one called, aah, a PC, well i won't say anything to that one Link to comment Share on other sites More sharing options...

Both are able to produce great renderings... mmm... well yes, the same goes with Caligari, nice few images, but interface is way strange. Only a very few fanatics can really do images there, I have used it and is WAY outdated software... EIAS just recently added OpenGL! As a "feature" common! On the mac, I will definitely pick from LW, Maya or Cinema4D. For 3D Arch, perhaps between C4D and LW. C4D will have a faster learning curve than LW. That is my opinion David Link to comment Share on other sites More sharing options...
Cesar R Posted June 1, 2003 Author Share Posted June 1, 2003 David, do you have a test model or scene you can share with me to get an idea of how to put together architectural projects? it doesnt have to have textures. - note before anyone says anything stupid like in the past. - i dont plan to steal your work or style , im just looking for some help. bc i know your good at LW. thanks Link to comment Share on other sites More sharing options...
ingo Posted June 1, 2003 Share Posted June 1, 2003 Yup, EIAS is a bit behind, but still a pretty fast renderer; but you still cant use the raydiosity engine. Hi Cesar, i think the only way to get a feel for the software is to test it, since everyone has its own way of structuring projects. Just use a standard project and try to rearrange it and see how you can work with it in your renderer, my first work with Lightwave needs a lot of rearrangeing until it went the way i want it, for example it depends on what you want to exclude from Lights/Raydiosity while rendering and of course the different texturing. Remember, try and error are your friends Link to comment Share on other sites More sharing options...
Cesar R Posted June 1, 2003 Author Share Posted June 1, 2003 yeah you are right about that trial and error. My main concerns is going from archicad to LW for rendering. I guess i would have to place all my windows in one layer and walls in another with in archicad and hope for them to import that way into LW via 3ds. BTW, how do do you name layers in LW and is there an instance tool such as the one in MAX? Link to comment Share on other sites More sharing options...
dwright Posted June 2, 2003 Share Posted June 2, 2003 Hi there.. Sorry, I cant give you our files.. I hope you understand. But feel free to ask me any question. David Link to comment Share on other sites More sharing options...
Cesar R Posted June 2, 2003 Author Share Posted June 2, 2003 I understand, Anyway how do you name layers and create layers? where are the help files.. i need to buy a book dont i? Link to comment Share on other sites More sharing options...
ingo Posted June 3, 2003 Share Posted June 3, 2003 Well for layers i put the at least all glass elements on one or more different layers, and the rest of the windows on a different one. So you can work with shadow maps or raytraced shadows. Otherwise i use a construction hierarchy or work with layers by material, but it depends on your working method and what your client usually changes during your work. i think if you just start to work with a lot of layers/objects its easier, because you later can combine things very fast. And take care that you use for polygon heavy elements like a roof with modelled roof tiles a seperate object, that makes it easier to switch it of in views in LW layout later for a faster workflow.

You can find all the info in the manual, as you know, the manual is huge.. Take the time and read it. PAGE 20.8 Resent update 7.5c has help files in addition to the manual. good luck!
