Need some pro advice for 3d matte

[riktor]

Im currently working on a demo reel piece and Im having trouble preping it in photoshop. What Im trying to achieve is a Spiderman esque shot with a camera panning around a piece of a high rise. A character will be standing on this piece and looking down (if I have time for more then just a mockup of the character) But the point is to show off the environment and I intend on making a large matte projected on geometry so I can do a parallaxing ending camera move down toward the end of the clip. Here is a link to the maya playblast avi (Let me know if you need another format). http://www.blurred-pixels.com/mp_images/pb.avi

So as you can see its a rather large move, but the only thing that really needs to be fully 3d is the mockup of the FG building the rest can be projected or cylinder mapped for that matter except the bottom buildings in which I will eventually animate the camera moving down into a bit. So my plan of attack was this, pick some key points in the animation and render them out with a Image based lighting sky dome and a Final Gather solution at triple 720p Rez. Then photomerge them in photoshop and overpaint the matte over the fully merged renders. From there I would take those same key renders and make camera duplicates that would project that portion of the whole matte back on to the geometry. There some issues with this though, for some reason photo merging is not working. It gives me errors about not being able to merge all the images and then poorly processes what it can do sometimes not at all. Im not adding any sort of perspective assement or anything since that may cause projection issues yet PS will not correctly merge the images. Now before you ask, Im doing this for the main reason of maintaing perspective through the painting and to create a overall large painting that can put into a portfolio or displayed in an other the video means for breakdowns and such.

So is there a better way to approach this or is it that I need more detail or color information to complete the photomerge? If anyone can offer an approach to doing this correctly I would greatly apperciate it.

And before anyone asks the foreground building is not part of the key renders because of its ability to damage the photomerge. As for the rest there really isnt much if any parallax at this point so it shouldn’t hurt the photomerge because of that, though parallax will be a factor on the final.

Thanks for the help in advance.

hi riktor
photoshop’s photomerge is not a fine-tuned tool imho.
CS3 has improved, but both CS3 and CS2 can yield clunky results: if your images are very large, it will really struggle to process them, and the blending between plates is not great at the best of times. if you get the message that it cant blend certain plates, its usually because there is not enough overlap between the images: photoshop cant recognise enough edge elements clearly to register the plates correctly. (usually you can drag the offending plates down into the photomerge window and add them manually to the merge)

perspective is the major benefit of this plugin: if you can simulate the perspective using the transform (+warp) tool (possibly combined with lens distort–may be overkill), perhaps manually blending layers with masks will get better results. (you will also have more control this way)

depending on file sizes, this sounds like it could be slow going
best of luck
it would be interesting to see the results

Thanks for replying, unfortunately for me this shot isnt a nodal pan and every resource I have found has suggested that to do it with projection only shots would be rather more effort the worth and that combination of 3d and mattes would serve me better.

Need a better program than 3d max to make a high graghic game? i am good at 3d work.have a group of hard working friends like me with good experiance with programing so all i need is a program better than 3d max .But 3d max 9 is not so good as expected please tell me a better program that is good and yoused before for good succesfull games hitman has good graghics something like that

i would suggest that 3DS max is one of the best 3d softwares to handle the stuff you are looking for!
for game developments and related stuff 3ds is one of the most comprehensive software!!also if you want to develop a game you can also use the UDK to develop a game!! and graphics are related to the the engine which supports those intensive calculations of the dynamic rigid body and soft bodies…etc!!so the software packages do the integration with it!!
