Advice/Tips required for my project..
I was wondering if some of you can give me suggestions on my first matte painting attempt.

Basically, I have to create a 5meter (16 feet) x 0.7meter (2.5 feet) matte painting. I don't know if I should even call it matte painting :D Its more of a landscape image that will be hung in a room like a painting.

So far I've collected images and tried to combine elements, and would like to do some 3D modelling and combine it in the painting.

My dilema is that it is impossible for me to work in one perspective guideline for the entire image because of its size. I have instead broken down the painting to a left, center and right side, each with its own perspective guidelines as required.

I was wondering how do I go about setting up a camera on a 3D program like Maya (or Max) so I can model and place objects in the correct perspective. Since this painting won't be used for a video, the camera will be static.

I'm confused as to if I have to just go ahead with modelling and adjust it so it looks correct on the camera against my painted background? i assume doing this will give me wierd geometry.

I hope I haven't confused you all too much :D

appreciate the help.

I've attached an image of my rough painting... more of a collage right now.. the white lines are rough ins of where I plan to place 3D geometry.

What you are talking about is 'spherical perspective'. It's weird, unintuitive and, quite frankly, a royal pain to work with.

The perspective grid for a full 360 cyclorama looks like this:

Most of the lines you would think would be straight are actually curved. It's possible to work it all out manually, but this is something where some rough 3D geo and a panoramic camera would save a lot of headaches.

If you don't want the 'fisheye' effect, then you could cheat the image, and keep the lines straight, with lots of different vanishing points. - but this will look exactly like a collage, since that's what it will be.

Well, you've got yourself one hell of a task for your first matte painting.

What will probably work best for you is this:
Model basic shapes in a 3D package. Set up a camera and animate it rotating 360. Render the animation in such a way to get a sequence of about 30 pictures covering the whole horizon. In photoshop do File>Automate>Photomerge, load your pictures and let the magic happen. You will hopefully get basic cyclorama to work with.

Then go nuts on the matte painting itself.

Hope that helped.

Ive just had problems with something like this. Is there any tutorials or info around on producing this kind of image because id love to be able to produce cycloramas
