Enising Inc's Photo+CG Montage "Behind the Scene"

At your request, Enising Inc.'s Resident Muse ma'am febx-tine wrote specially for all of you a quick tutorial on how we did the Photo+CG montage images here:

If you have questions, shoot and we'll try to answer. I will expand on step no. 2 later.

If this tutorial helped you, please let us know, thank febx-tine and send us some cool photocgmontage images. If we like it - who knows we might even send you some work.

Goodluck.

tnx a lot sir... ma init2x pa.. hinihintay ko to!! is there any way we can view these images in big? hi-res? sori sir request lng po...

If you go to the link below the images:

It will take you to my Picasa site and you can download the original image there (2500+pix). I'll ask febx-tine to make a pdf copy later.

As for efficient light matching, I will expand on that topic in this thread at a later time. Uwian na!
Well take it slowly although I do not want to confuse you. The concept is basically the same as this one I posted long ago.

Great presentation still even with this tutorial.

If this tutorial helped you, please let us know, thank febx-tine and send us some cool photocgmontage images. If we like it - who knows we might even send you some work.

Is this addressed to max users?

We don't care what software you use, actually. But if it's max - we can always be there to help you if you have problems.

Important thing is, it has to be quick, fast and painless for you - otherwise we won't be able to afford you...

galeng...! thanks for the kindness... sir vertex...!

Ok verts. This is a good opportunity for everyone. Malay nio d ba.

i wanna try it....it's making me curious...thanks for sharing sir...looking forward to additional inputs from you.

Curiosity is the root of greatness. Pagpatuloy mo kabayan!

Thanks for these, really inspiring indeed. Makasideline nga sa enising. haha. keep it up guys! thanks sir V.

Hahaha! Kaw pa, dami mo nang business eh. We'll talk bout that off-forum

kudos to ms. christine capucao for making this tutorial... sya kasi nag hahandle ng mga montage po..

Late ka bat ngayon ka lang. Salamat Cray as always for being the great apostle...

saw some of the images sir V sa multiply buddy kita dun eh..hehehe pero d ko pa makita lahat ng images..bagal ng net ko..

kahit etong tutorial di rin..ban ata picasa dito sa dubai.

anyway panalo lahat ng images

ang galing nga ni miss tine...at maganda pa, ang gaganda ng mga tine ng CGP...hihihi....

may napansin pa ako, pati mga jay sa CGP, magagaling din....

Back To Topic:

I managed to create a PDF version of the said tutorial. I'll try to host it somewhere, or just send me a PM, and i'll provide a copy.

Thanks Arkiemund, feel free to distribute it.

Oo nga pala grayback. If you need a pdf - arkie is the man to bug!

^^
My pleasure sir vertex...

We are excited on your in-depth discussion of step 2....

pwede pala ang ganito sa max... kala ko yugn Sketchup hanep dito. tagal na pala sa max ang ganito. thanks for putting it up roy. i guess i need to do the same thing in SU, paki silip nalang kung may recommendation ka especially paano i match yung ambience ng enviroment sa scene. meron kasi akong ginawang tutorial way way back and this is how to actually baked the actual picture background mismo sa scene. hope i could have more time to explain it later and indeed its a quickie yet parang ganito madaling maconvince yung viewer na kasama yung actual picture sa whole scene.

I was planning to write a more indepth explanation of matching the lighting later, but since you asked, I will try to sum that up briefly for the meantime.

Camera mapping:

We bake (Per Pixel Camera Map in maxspeak) the background photos to the simple enclosures (walls, floor, etc) so that we will have GI emitters that would simulate the general ambience of the scene. The purpose of the camera mapped walls or enclosures is actually two-fold:

1. As GI emitter
2. As raytrace reflectors for 3d objects that should have reflections. I would really insist on putting reflective objects like vases, glass, etc because those objects, once they reflect the floors and wall and other elements in the background, they will serve as some sort of a tier - they create the illusion that the virtual objects in the scenes are actually part of the whole scenario. This is the same reason in vfx why we put reflective objects in the scene even though they aren't necessary. It's like magic - you trick the viewers into seeing and then believing that what they are seeing is real or part of the open space's reality.

So I repeat, the purpose of the camera mapped walls is to make them shoot GI and as an automatic environment map.

An added bonus of camera mapping is that since they stick to your meshes, you can also render them from another animated camera for quick 3d pans, or 3d zooms as long as the BG map's density permits. So you can make this single BG image act like they are 3D.

Now for light matching,

the first step is to place your lights in the same position as in the background picture. So if you have a ceiling light there, put a planar light or object light in its place, Now if you have openings like windows, you can make them hollow so that the direct light (sun) can get in. You can also put planar vraylights in there as skylight portals so they can pump in the GI from the environment. You can also put in the windows, camera mapped planes that are either strongly self-lluminated (high RGB values in the output rollot) or VrayLight Mapped. The added bonus of the latter is that they will also appear in the reflections like in real life.

The next step before you populate them with 3d objects is to test the lighting and shadows with a sphere or any simple object. I usually start them with a white material (some prefer grey - but greys doesn't burn out easily with strong lights and it defeats my purpose).

With the simple object in place, I try to find objects in the BG photo that I could assume as white-colored in real life. This could be walls, or paint, airconditioning units or any other element in the photo. Make test renders and try to mimic the same white balance in the dummy object by carefully adjusting the intensity of all light sources including the GI without touching the dummy object's white material. Do the same thing for shadows, adjust positions of lights or sizes so that they produce the same shadow angle and intensity.

Once you have done this and has acquired an acceptable white balance similar to the photograph, this is the time to put any object you wish.

Kahit ano pa ang ilagay mo dyan o anupaman angle - you will get a good overall match.

Di ko pala kayang i-brief! I just realized that it might be a little diffucult to understand without any illustrations, I'll try to cook up some illustrations soon.

Yung iba pang details at yong paraan ko sa pag mano-mano perspective match ay sa susunod na lang po.

I look forward to your tests in SU! Goodluck.

Very well explained sir...i copied your entire text to notepad....hahahaha....may utang na ako sa yo...hehehe....sisig lang naman katapat nito sir diba...

Looking forward to the other juicy bits of this concept.

y i cant view the pis??....

thanx sir for this, laking tulong to sa akin

@sir vertex...you mentioned something about white balance.

We have that discussion about that at a thread on CG Discussions, but unfortunately, it suddenly shifted to discussing about LWF.

LET THE BALL ROLL AND HAVE SOMETHING DONE

So, with your permission, I'd like to repost PART ONE of the tutorial that you provided, on that thread, somewhere in the tutorial section, so we can finally finish that discussion on white balance as well.

I'll be waiting for your reply right here...

thank you..

ang galeng sir V... sana maging apostle moko...hehe
