Devin Johnston Posted December 7, 2012 Share Posted December 7, 2012 Passes aren't necessary in order to get the photo real look your taking about, all passes are are different elements in your scene rendered out separately and then it's up to you to put them back together.

Devin Johnston Posted December 7, 2012 Share Posted December 7, 2012 I didn't say passes couldn't improve your images they can and do if you know how to use them, however you can't depend on passes alone to make your renderings look photo real. Most high end renderings don't come out of the render engine looking perfect, there's always some Photoshop work going on behind the scenes. Most people use passes to enhance what's already there, if you render out the right passes and combine them correctly you can adjust lighting, reflection, refraction, and AO very easily. That's what they are good for but if your scene doesn't already have that photo real quality to it before you get to Photoshop all the passes in the world won't help you. The problem is that it's difficult to render out a scene in passes and recombine them, if you don't do it correctly your image will look worse than it did before you began. There are tutorials on how to do it, you should do a search and try it for yourself. Link to comment Share on other sites More sharing options...

salvador Posted December 7, 2012 Share Posted December 7, 2012 Like Devin said, passes are the breakdown of what you get in your VFB. You can re-assemble your render in PS by using the passes. That's your choice. The key point about passes is the ability to control the physical elements inherent to your scene, namely reflections, global lighting, refraction, intensities, etc., which you cannot do in your RBG pass alone. Nonetheless, you can still make corrections in PS without passes, using the many tools provided, such as Curves, Levels, Exposure, Color Balance, Photo Filter, etc.; this is regularly faster than re-rendering because the image looks dark or too bright or dull. My best advise, take the time to google for and read about it so you can have a better understanding about this. It would be a hard task to write down an entire workflow on passes in a single reply. Take a look into Evermotion archinteriors / archexteriors volumes at http://www.evermotion.org - the first volumes had no post-production and were not re-assembled in PS. The later ones are and the PDF samples show the before and after. Good luck Link to comment Share on other sites More sharing options...

M V Posted December 7, 2012 Share Posted December 7, 2012 Once you learn how to use passes and IDs, your world will never be the same. Rendering passes and rendering to 32 bit EXR using LWF is like roids for your images. So much more power and flexibility to edit lighting and tweak colors and material properties. I wouldn't do it any other way now. Link to comment Share on other sites More sharing options...
MohammedYusuf Posted December 7, 2012 Author Share Posted December 7, 2012 Thanx mathew fr ur comments....since u r using passes...i have 2 questions , there are so many passes in the element section...while rendering do we need to add all the elements or there are certain elements to be used.

salvador Posted December 7, 2012 Share Posted December 7, 2012 The best help now is not answering straight, no offense intended. You can find all about it on the internet for free and that will be the best way to learn. Be advised that it takes time and practice and there really is no "the way" to do it. I saw your work and I like it. Please try not to get into the fast track; don't limit your field of action. Link to comment Share on other sites More sharing options...
John Dollus Posted December 7, 2012 Share Posted December 7, 2012 you don't need every render element. To suit as wide a market as possible, Vray programmers provide many more options than what is needed. There are several ways to recombine depending upon your post production pipeline. Also, I find arch vis needs far more material mask passes than the subtle tweaking of refrac/reflect/shadows that other markets seem to use. If you recombine based on vfx pipeline, altering materials can get needlessly complicated for our limited budgets Link to comment Share on other sites More sharing options...
