chalk Posted October 7, 2006 Share Posted October 7, 2006 Hi all, this is my first post here. Great place! I spend most of my time pestering people about archviz tips on other forums and now ive found a place completely dedicated to it. Great stuff! Heres an image im working out. It started as an empty room purely for testing lighting setups and now im starting to slowly add a few bits - the modeling is still a bit shakey and theres not much detail at the moment. Comments and ideas all welcome, specially on the lighting and realism factor at the moment. Are there any other C4D users out there? I've seen some amazing stuff done in Vray which almost made me question my desicion to go with C4D but i've recently seen some masterpieces done in this programme which has given me more faith All i need to do now is figure out how to get good results - lighting is a constant battle of mine!

STRAT Posted October 7, 2006 Share Posted October 7, 2006 nice start Karl. yup, loadsa c4d users here lighting is a constant battle for everyone. makes or breaks an image. vray is an awesome radiosity renderer, with much better usability, but a good artist can make the AR just as good as vray imo. i'm not going to jump ship any time soon for beginners your lighting isn't too shabby. you wouldn't see any blue on the walls or ceiling, so you might want to turn the wall/ceiling's material saturation levels down, or turn the blue luminance down. also, i pressume your diffuse depth is 3 or 2? (your immediate radiosity effect looks this way - too much) try a dd of 1, and if it doesn't look bright enough try compensating with infil lights or your gi emmitters (ie, sky). even in low lighting conditions i find a dd of 1 much more realistic. (dd of 1 speeds up rendering 200-300% too ) you might also want to try mixing a touch of ambient occlusion into your work flow. it's simple to use and really lifts the gi in most cases.

manta Posted October 8, 2006 Share Posted October 8, 2006 I don't think Vray is a radiosity renderer, I always thought that it used the Monte Carlo method, if it were a radiosty renderer, it would be view independent... Link to comment Share on other sites More sharing options...
chalk Posted October 9, 2006 Author Share Posted October 9, 2006 Cheers for the comments. I'm currently messing around with a few of the things you suggested so see how it goes. I've got the ambient Occlusion plugin for c4d 9 now as well so i'll have to figure out how to use that now :@) Link to comment Share on other sites More sharing options...

Can you tell me what you mean by the Monte Carlo method and what does view independent mean? thanks. Lee Link to comment Share on other sites More sharing options...

chalk Posted October 9, 2006 Author Share Posted October 9, 2006 ..... so i must be a Noob as well, titled this thread about GI but im using the Radiosity from C4d's Advanced Render... i thought they were all the same thing to be honest :/ Just been checking out your site as well STRAT, some very nice stuff there! I'll defo be quizzing you and how you got a few of those nice lighting effects Have a look at mine as well if you like - http://www.k3-d.co.uk - which is my own Archviz company i setup - Some of the older things i did are a bit crap so ignore them :@) Link to comment Share on other sites More sharing options...
Frosty Posted October 9, 2006 Share Posted October 9, 2006 C4D is technically GI - not Radiosity. Link to comment Share on other sites More sharing options...
chalk Posted October 9, 2006 Author Share Posted October 9, 2006 Ahhhhhhh haaaaaaa. So when i enable radiosity it's NOT radiosity but GI.... clear as gunk. I'll have to go through some of those articals when i get time! Link to comment Share on other sites More sharing options...
STRAT Posted October 9, 2006 Share Posted October 9, 2006 gi and radiosity are 2 different things Link to comment Share on other sites More sharing options...
jackb602 Posted October 9, 2006 Share Posted October 9, 2006 I think that Cinema, as well as much of the CG world, uses the terms interchangeably and not entirely correctly. Radiosity is in fact one method of calculating global illumination for a scene. In fact, I don't think Cinema has ever used this technique, but rather a kind of photon mapping. In a recent release (R9? R9.5?) they changed the name of the tab in the Render Settings from Radiosity to Global Illumination, for accuracy's sake I imagine.

chalk Posted October 11, 2006 Author Share Posted October 11, 2006 I've managed to have another mess around with the scene, tried adding and array of lights and toning down a few things. It's seems to me that some of the furniture is floating a bit though, the array of lights has soft shadows on. A few little touches like making the curtains hang in a more natural way would probably help as well. and maybe some more bits'n'pieces althought my minds gone blank on what else to add. Any suggestions? and comments? Link to comment Share on other sites More sharing options...
STRAT Posted October 11, 2006 Share Posted October 11, 2006 much much much prefered your very first image on the top of the page. this last one is almost as if you've turned off all gi. Link to comment Share on other sites More sharing options...

If so tell me what is the difference between the Monte Carlo approach and a Stochastic mode algorithm? ; ) oh, do you know of any good tutorials on making a cushion ? : ) Lee Link to comment Share on other sites More sharing options...
STRAT Posted October 11, 2006 Share Posted October 11, 2006 oh, do you know of any good tutorials on making a cushion ? : ) Lee did have, but i lost it. again. besides, i got a mate who does all my fiddly bits for me. why should i bother? Link to comment Share on other sites More sharing options...
