ROBLOX characters have super powers. They can jump higher than they are tall and can climb up any hill, no matter how steep. Up until now, game creators had no easy way to control these powers. While this may be appropriate for some games, many game creators have been asking for a way to let them set how humanoid characters behave in their worlds. Some creators looking to disable jumping all together, while others seek to simulate low gravity moon physics, some have expressed a desire to use unclimbable high hills to direct characters down certain paths.
Particles are a staple in computer graphics and game creation. They’re an easy way to create flames, smoke, explosions, sparks, splashes, weather, dust, and even abstract effects, such as the wispy, glowing trail behind a magic spell. These kinds of effects can set the atmosphere and mood of your game, make vehicles roar to life, bring excitement and visceral feedback to combat, and more. Now, with Custom Particles, you have the freedom to change the existing ROBLOX particle effects – and the power to build beautiful and creative effects of your own.
The ROBLOX Rendering team made 2014 yet another year of beautification for ROBLOX, unveiling such eye candy as new particle effects, new material textures, and environmental reflections, and even transitioned to an entirely new rendering engine developed just for our platform. To top off the year, this week the team launched two final updates: a new texture-rendering technique that reduces repetitious tiling, and a new explosion particle effect.
The recent release of our Solid Modeling tool ushered in a new and exciting era of creation, in which builders and developers have the ability to create complex objects using ROBLOX’s primitives as a foundation. We’ve seen the potential of the feature become a reality, with a plethora of impressive games and worlds leveraging the tool to great visual effect. Today, Solid Modeling has received its first substantial upgrade: accurate physics simulation for complex objects.
Today, we launched our revamped particle effect system and a new look for the existing particle effects: smoke, fire, sparkles, and the spawn forcefield. All of these particle effects were completely redesigned from the ground up to fit the high-quality and high-definition look that we’re working hard to bring to ROBLOX, and several key members of the Rendering and Art teams collaborated to redefine what ROBLOX particle effects are. It was important to us to ensure that implementing these effects in Studio is the exact same process as it always has been, which it is. As Senior Software Engineer at ROBLOX, I want to share an under-the-hood look at the technology we developed to implement the new particle effects, and talk about an interesting challenge we overcame in the process. Get ready for a deep dive.
You’ve no doubt noticed the “Enable 3D” button perched next to your favorite hats, gear and packages when you visit the pages of catalog items. Starting today, we’ve enabled the 3D view for shirts and pants as well, giving you the ability to view clothing from any angle before you buy it (or decide not to because of what’s on the back). Using the Rendering team’s OBJ Exporter as a foundation, we were able to roll out this feature and make it possible for you to take a 360-degree look at hats, gear, packages, heads, clothing, and characters on roblox.com.
Today, we launched a rendering update that gives reflective objects – both parts with a Reflectance value and terrain water – dynamic reflections based on the sky, the sun and moon, and the time of day. This is a relatively subtle change with a noticeable effect on the immersion of ROBLOX gameplay. Continue reading →
