Hi,

This tutorial was not intended to be used for matte painting.
The occlusion option help you only to visualize the area you need to paint.

In fact you have many ways to get around this issue :
- generate the occlusion and dilate the alpha in photoshop or paint exactly what you need
- layer your scene and paint specific matte for each of them to avoid echoing
- use an intermediate camera with overscan to cover the full animation (still with proper layering)

In both of your example I will project a different image for the BG (further you are and more parallax you get) with the blend already done in your 2d software.

We will do later an in-depth tutorial for matte painting in Clarisse.

Cheers.

now i'm confused, are you using occlusion as an alpha, no wonder there's holes, or is AO useful in camera mapping like shadow catcher?

Aymeric was referring to the camera occlusion in the projection mode, not ambient occlusion which is something completly different..

I was thinking maybe the ambient occlusion was being used for some composition purposes, getting mixed up with similar thread matte painting, I will have to try this example one day to see if whilst doing it it gives me a better understanding of how it could be used, simple examples dont immediately translate to a useful scenario with me. I remember camera mapping(not sure if it's the same) once or twice in max but only because I was following a tutorial, relying on 5 points in a picture to reverse engineer camera position, I never ever needed to do it in real world. if there are any other examples of it in use i'd like to see them.
