3D Matte Painting Tutorial

[jonahmwest]

Hi, I made this tutorial recently, it covers concept painting, matte painting and 3D camera projection.

Please enjoy: http://conceptartandmattepainting.blogspot.com/

Welcome to the forum and it's really useful tutorial you got there...

Nice, simple and easy to follow with a great end result. I wonder: why use a Surface Shader when a lambert will do?

Thanks for your comments everyone, the reason I use a Surface shader is because when you use a lambert Maya pre-multiplies the color channel with the alpha and you end up with a black ring around the edges of you image. Surface Shader doesn't pre-multiply

Nice, thanks for the workflow.

This should be an interesting part "...To Complete this shot, you could add some moving elements such as video footage of waterfalls" ... :-)

If have tried a seamless MP / camera projection on a Video Live Footage integration (Canon 7D Full HD Shot), but i give up, because the photographs don't work, don't matched with the footage (perspective, Noise, Grain, Blur, etc.)

There green areas should replace.

Here is the shot:



Perhaps you can make a Video tutorial free or payed with Mattepainting and Live Video Footage integration

@Eagle1: You need to track the footage and solve a camera to render from - that's why the footage doesn't match up. Google things like PFTrack, Boujou, Nuke.

@Jonah: Thanks for the Surface Shader tip. Keep up the great work!

Thanks for the hint the scene was tracked in Syntheyes, thats not my problem....

As i wrote above the MP look and feel don't matched with the footage (perspective, Noise, Grain, Blur, etc.).

Live Footage (DSLR Shots or RED) has a special look. So its "easy" to create a MP from scratch, but the MP integration in a Live Footage is a complete different workflow.

For this art of seamless broadcast quality and 100% photorealistic VFX Mattepainting i missing tutorials. The Gnomeworkshops MPs for example are superficial with no focus on the important details. They cheat with colors, details and create a cartoon look, but its unusable for VFX in Film.

I need some hints for Real Footage VFX Mattepainting and 100% photorealistic, without the typical fantasy look in the tutorials.

Here is a Full HD Screenshot of the scene, if any one likes to try.

The left side of the road should a scattered city and deserted Mountains in the background.

Eagle1, i am not an expert in matte painting, but as far as i understand concepts and workflow should be very same for stylized and more photo-real work. In your case it seems to be more of compositing challenge (color grading, de-graining and re-graining, color-matching), to perfectly match live plate with cg elements, but in terms of camera setup, layers separation, geometry blocking etc. it should not be very different.

Yes, elements graining and blur thats the main problem with LIVE Footage integration....

Here is a first Mattepainting Test shot of this scene:

Just see how it works on the movie....

The first thing I notice is that the house in the FG are a little unsharp and the edges, they are way to blurry.
The seam between the ground and the objects are not really correct either, then the edge of the "fence" between the road and the FG-house are not masked enough. Then there are no shadows.

I don't know if this was a draft, but there you have my five cents.

Cheers!
