Figure 1 shows 48 cubes textured using the seven images shown in figure 2. The shading network shared by all 48 cubes is shown below.In Maya create an arbitary number of objects. Set the project and save the scene.1 In the script editor execute the following mel proc.Global proc addAttributeTexname(string $texturesDir) В will be substitued by RfM for the actual path to the current Maya project directory.Unfortunately the current version (21.0) of RfM the PxrOSL node ignores the shader's metadata. Hence, 's' and 't' are not hidden and 'invert' and 'linearize' are not displayed as checkboxes!For more information about using OSL shaders with Maya refer to the tutorial 'OSL: Use in HyperShade'.The successful operation of this technique depends on a couple of important factors.Firstly, Maya's project directory must be set the scene must be saved. Secondly, the texture files have been saved by the Texture Manager in the directory specified in figures 7 and 10.

Jacobs, Alejandro Jodorowsky and Ridley Scott. Even so, the property resisted adaptation to the big screen for some time, despite attempts by Arthur P. A science fiction novel dealing with concepts ranging from the nature of messiahs to ecological concerns, Dune rapidly burgeoned from underground cult classic to a huge and sustained success worldwide.

The work was just so strong, with such defined ideas вЂ“ there were s ome tweaks down the line, but really it was very close. Usually that process just serves as a springboard for the final designs, but Denis was so happy with the initial artwork that it really served as a template for other departments. вЂњSo Denis and Patrice spent the better part of a year coming up with concepts. вЂњDune is such a massive project, with so many worlds to visualize,вЂќ he acknowledges.

Sets were built with these same colors and textures, and visual effects created and executed these images in a similar faithful way.вЂќвЂњNo wild pullbacks and moves that didnвЂ™t have some basis in how cameras are actually moved, and we tried to build as much as possible on most of our sets rather than encasing actors within a blue box. The work was just so strong, with such defined ideas вЂ“ there were some tweaks down the line, but really it was very close. Production opted for the flapping wings to flutter like an insect in flight.вЂњ Denis was so happy with the initial artwork that it really served as a template for other departments. The AtreidesвЂ™ ornithopters incorporate the articulated wings described in Frank HerbertвЂ™s novel. вЂњHaving worked with Denis previously, I knew that things had to remain grounded,вЂќ confirms Lambert.

They have Deak Ferrand, a fantastic artist who is one of the fastest conceptualists IвЂ™ve ever seen. The in-house unit wound up doing hundreds of the simpler shots, plus we did a few shots with Rodeo FX up in Montreal. вЂњI think it is very valuable to have offices close to the director,вЂќ says Lambert, вЂњas it facilitates the fleshing out of ideas, which in turn affects and improves the shooting process. While there wound up being around 2,000 visual effects shots, realism was the word throughout.вЂќWhile the majority of work was handled at DNEG Vancouver and DNEG Montreal, an in-house crew, overseen by WylieCo, was also formed for the production. In fact, the shield effect is based on past and future frames in the same shot, plus some color changes, so it isnвЂ™t like weвЂ™re adding or inventing, just using what was actually there. We tried to avoid anything too FX-y, even when the ships fold space.

We built that CG world around those real terrain elements.вЂќFor backlot work in Budapest, sand-colored screens were used instead of blue or green, allowing a more naturalistic Arrakis-desert coloration to reflect onto the performers. вЂњOur beautiful wides of the city are actually from helicopter views scanned into the computer. вЂњThat helped with the wides of Arrakeen,вЂќ he reports.

We could only shoot at a certain time of day with this tarpaulin because the hole permitted sunlight to illuminate the interior just right for a couple hours only, but it really sold the reality of the environment with natural lighting beaming down into our stage sets.вЂќClose collaboration between VFX, camera and art departments led to a unique approach for interiors requiring set extensions. вЂњWe connected two separate studios with a tarp across the roof, which had a specific shape cut into it allowing sunlight to come down into part of the set. вЂњFor some massive interiors, we had to come up with creative ways to light the scene,вЂќ Lambert reveals.

That meant pouring a concrete pad for the thopter. вЂњOur two computer-controlled motion bases had to function on location,вЂќ he says, вЂњbecause our DP needed real sunlight and could not create that look on stage. That needed a 400-ton crane, so a special road had to be built to accommodate transport.вЂќNefzer used various gimbals, plus an overhead flying rig hung from a crane. We had one scene with the big ornithopter landing in the desert and then taking off. The big one weighed maybe 13 tons and was 10 or 12 meters long, so making it look as if it could maneuver took a lot of power.

We had four six-wheel drive trucks from the military so we could mount and drive our big wind machines around into position. It could rotate 360 degrees so that the actors could be upside-down. We tented the smaller base with wind machines and tons of dust flying around in there, including soft stones, so that the view through the cockpit would really look like it was flying through a sandstorm. The large base was rated for 20 tons and the smaller thopter used a six-ton base for sandstorm scenes.

Paul Lambert always asked for as much practical as possible to have something to match вЂ“ вЂeven if it is just a few metersвЂ™ he said one time вЂ“ and then he filled out the rest of the shot beautifully. But the part of the shot that we could handle practically вЂ“ the area around the actors, because you get such a greater sense of believability with performers having to lean into the dust as they move instead of just pretending against greenscreen вЂ“ was the basis for how VFX went about completing things, matching to the look and density of our sandstorm.
