drvox Posted October 12, 2006 Share Posted October 12, 2006 Hi all, I'm working in an exterior scene like the one attached here...this is one of the best exterior scenes I've ever seen... I got it in the evermotion gallery and stayed looking for it... I wonder if anyone can give me some ideas about the lights used and vray render settings used to create this kind of quality in exterior scenes... I can handle with interior renderings, but I'm having some difficulty on getting photorealism with exterior scenes. And if someone can give me any tips to create building exterior glass like the one showed... Thanks a lot, King Regards Link to comment Share on other sites More sharing options...

danatgia Posted October 12, 2006 Share Posted October 12, 2006 Forgive me for being harsh, but I don't think this image is all that great! You could easily produce something like this with your interior settings. Check out the Chos Group forum for some good ideas. Also Evermotion themselves have some good tuts!

AJLynn Posted October 12, 2006 Share Posted October 12, 2006 Actually, that doesn't look all that difficult, and some parts are a bit strange - the facade above looks like a photoshop job, it's not in the same focus as the facia below it, and the hard corners of the ramp really stand out. The bush on the left is not very good, and the plant on the right is gray. But... for the exterior lighting, there are a few ways you could go. Looks like GI environment is turned on (for a better effect you could make that an HDRI) and there's a light for the sun - I can't tell what kind but it doesn't matter that much - with area shadows. Probably irradiance map GI, and it looks like secondary was probably light cache. The glass is probably just a Vray material, dark with a medium reflection, no transparency so you don't have to worry about the interior. The important part is that it has an sky with good contrast to reflect. The chrome is easy and grass is sometimes hard but that looks like maybe displacement with a pretty standard map. I'd like to see more edges bevelled, more bump maps, and reflection maps, and more work on the shot composition. I'd recommend you watch Chris's DVDs (the Gnomon Global Illumination series - you can get them from the Shop link at the top of the page). Link to comment Share on other sites More sharing options...
manta Posted October 12, 2006 Share Posted October 12, 2006 I think that the glass is too reflective, you should be able to see at least a hint of what's inside... Link to comment Share on other sites More sharing options...
drvox Posted October 13, 2006 Author Share Posted October 13, 2006 Well for me it is a wonderful scene...at first view it looks more like a picture...but I'm just a beginner in 3d so I bealive you must be right...anyway, here is attached the best I could get with vray in a exterior scene.... I've tried IES sun, but this picture has Target point photometric lights.... I aso tried the Vray Light but I couldn't get anything acceptable... Can someone please tell me a nice tutorial, or maybe just something that can help me get the quality of that picture I posted above... Thanks a lot!

danatgia Posted October 13, 2006 Share Posted October 13, 2006 Its a good start! You NEED to look at lighting. Try using a direct spot with Vray Shadows as your sun. Position it perpendicular to the camera, maybe farily low in the sky and play around with a more orange/yellow colour. Textures on the building itself need some work but the grass is great. The glass looks okay too but you may need to put something in the reflection map. Camera position is also very important. Keep it low and at eye height and play around with (what I call) whacky Batman angles ie. rolled slightly to give a more artistic feel. Keep playing around and let us see the results!!!

AJLynn Posted October 13, 2006 Share Posted October 13, 2006 Take a while to work on the textures, and UWV map everything. Looks like you've got the concrete on UVW map planar with the plane horizontal, use box instead. Get some texture on the yellow stuff and bump and reflection map everything. More detailing would help too. Think about what camera shots you want to use, then make the lighting work for them. Take a look at how architectural illustrators and photographers compose their shots, and stick with 2-point perspective unless you have a reason not to. Forget IES sun and sky when using Vray, just use a direct light (very slight yellow tint) for sun like Dan said and the Vray GI environment for sky, and add some fill light later if you need it.

Brolloks Posted October 14, 2006 Share Posted October 14, 2006 Try the VraySun and Physical Camera in version 1.5. It takes a bit of getting used to but the results are worth it... Link to comment Share on other sites More sharing options...
drvox Posted October 16, 2006 Author Share Posted October 16, 2006 Hi all Thanks a lot for the suggestions... I used the Direct light and made a little change with uv mapping... didn't change the materials because I need to find some good tutorials about creating materials...reflections, bump, glossiness, etc are terms with which I'm not very familiried with, yet... Anyway here is what I got changing the lightning system.... I'll keep changing it.. I'll try now the vray sun... Thanks a lot and any suggestions are welcome!

Neil Woodhouse Posted January 26, 2008 Share Posted January 26, 2008 These sort of questions are a recurring theme on this and other forums, even i have asked these same questions and i still struggle to get the product right. I think what we really need is one tutorial that say's "This is how you do it" it would be nice to include all processes from modelling, thru' texturing, lighting, render engine settings etc etc. I appreciate that many will say that there are various ways of doing this, but i think we need one mega tutorial purely on this issue. I know we have the two gnomon DVD's, both of which i have and they are excellant, but we need one that is specific to buildings. My twopence worth......thoughts?

Ricardo Eloy Posted January 26, 2008 Share Posted January 26, 2008 I'm afraid it takes a bit more than a good tutorial, guys. Modeling, texturing and lighting a scene is not like a cake (follow a recipe and wait for it to bake). The important thing is that one has to understand the concepts behind a great image, and then apply them to his own. Chris' DVDs show the concepts, and those are the same everywhere, no matter what kind of scene you're doing. Besides, for beginners, I'd recomend Brian's course and books. He knows his stuff and covers all parts of the process. Link to comment Share on other sites More sharing options...
