Week 79 – Sky Matte Paintings

posted in: Textures | 5

One thing we wanted from the very beginning with this film was to be able to paint a new custom sky for every shot. Many ideas were cut because of time constraints, but we’re very happy that the skies aren’t one of them because it adds this nice aesthetic appeal as well as allow us to work out the clouds so that they compliment the compositions perfectly. So for this week’s post, here are a few of the matte paintings that were done in the last few days!

And as a little bonus, here’s a new composited shot featuring the mill and villagers in broad day light. Click to see in full size!

Well, that’s it for this time. We hope you’re enjoying your summer, and stay tuned for exciting news coming up on Le Gouffre this fall. Also, don’t forget to subscribe to our Facebook to always be up to date with the latest happenings!

Week 75 – Cliff Textures in ZBrush

posted in: Textures | 9

Many people told us that they would like to know how we did our cliff textures, so we’re going to show you just that in this week’s post. Beware to the non-initiates, it might be a little technical!

Now, what you must know is that the canyon in our movie is enormous and in order to obtain sufficient resolution everywhere, we had no choice but to separate it in multiple pieces and work the textures separately. Of course, a lot of work went into working the pieces seams to make the whole thing imperceptible.

While the biggest part of the work was done in ZBrush and Photoshop, the first step was in Softimage, where we had to find the right dimension for each cliff piece. Once done, a first layer of subdivision and modeling was applied to have enough detail to work once in ZBrush.

Here is what the first version of one of our cliff piece looked like right out of Softimage. At this stage, the Uvs have already been unfolded and will adapt once we start subdividing the model.

The second step is to subdivide the model as much as possible and sculpt the cliff until the result is a little more realistic.

It’s now time to use a very useful technique we discovered, which consist in literally projecting the ZBrush shading onto the surface of the geometry using ZAppLink. This way, we obtain a good texture base that follows the details of the sculpt. Then we only have to refine the lines, still in ZAppLink, to obtain the following result :

Since the Uvs have already been unfolded, we can simply export the texture in Photoshop and use this painting as a base to add color and smaller details. Here’s the final texture :

The nice part about all this is that since the texture was made using the sculpt itself as a base, the details of the cliff follow the modeling very closely once we add lights!

Well that’s it, I hope it wasn’t too hard to follow. Feel free to leave a comment if you have any more questions, and see you next time!
