First Update in Major Summer Launch: Smoother Enables Massive Terraforming
Intro With the introduction of the latest smoother tool in ST Engine (Smoother Preview), the ability to terraform landscapes has been greatly enhanced. This post provides a clear guide on how to use this feature to create large-scale mountains and complex terrains. The process will be divided into planning and outlining, blending, and fine-tuning. {STEAM_CLAN_IMAGE}/43374889/d458d3624d83a42ecfe429107e3d3d6a035d9f09.gif Quick look of Smoother A Tutorial To Massive Terraforming Step 1: Planning and Outlining Determine the Terrain Type Before beginning, it is essential to decide on the specific terrain you wish to create, be it snow-capped mountains, desert landscapes, or cave systems. Investigate the materials and geological features typical of these terrains. For mountains, consider the layering of snow and rock, taking into account weather exposure. For deserts, research what materials may lie beneath the sand. {STEAM_CLAN_IMAGE}/43374889/3c6ed4c1548aace9f62e5604e616414d045ecc8f.png Outlining base structure Outline the Basic Structure After planning, start outlining the terrain using tools such as volume and brush to create the basic structure. Utilize the volume tool to create a substantial foundation for mountains. Employ cuboid shapes to represent hills and cliffs roughly. Step 2: Blending Combine Materials Blending is the next phase in the process. Here, you’ll combine the outlined structure to create a unified terrain. Using examples such as mountains and hills, you can grow and shape your landscape. Various tools allow for the quick outlining and blending of terrain to reach the desired appearance. {STEAM_CLAN_IMAGE}/43374889/5c74113f72aad564e62ce60612a4d10bbc782881.png Initial blending with Smoother Step 3: Finetuning Refine the Landscape Finetuning utilizes the smoother tool to mix materials and achieve refined effects. The tool has two modes: one for detecting materials on the terrain, and the other for specific control. For example, snow can be highlighted...Read full article on Community Announcements (ST Official)AnnouncementsOfficial
Preparing for the MAJOR SUMMER LAUNCH
Sneak Peek at Riftwalkers' Demo We are thrilled to announce that the first playable demos of Riftwalkers are almost at your fingertips. We've brought to life an extensive array of dungeons and villages, showcasing Actual Gameplay that is more expansive and immersive than any of our previous releases. In Riftwalkers, you can look forward to an array of meticulously-designed, challenging levels. {STEAM_CLAN_IMAGE}/43374889/32a45c7c18a14fd8229a52a1d707b59a7ba5f45b.png Still wondering why we've named it Riftwalkers? Our previous post explains all: Unveiling Riftwalkers We are currently ironing out a few technical issues to seamlessly integrate the portal and modern-era levels into the game. We appreciate your patience and encourage you to keep an eye on our updates for more information. {STEAM_CLAN_IMAGE}/43374889/5ebe58e6d54da51da2eb5dde8639d5c75ef34d75.png Revamped Community UIs We've completely overhauled our marketplace system and replaced it with a freshly-designed community UI. This improved interface offers features like trending maps discovery, user-friendly like & dislike options, and a platform for posting comments. This fosters a dynamic environment for creators to interact, share ideas, and learn from each other. Enhanced Building Capabilities: Smoother and Undo We recognized that our game engine was struggling to generate curved surfaces and terrain, and we took your feedback on board. Consequently, we've developed and added a brand-new building tool, the Smoother, to our suite. We'll soon share more detailed insights on the functionalities of the Smoother in an upcoming update. We're also excited to unveil the Undo feature, which allows creators to revert material changes in case of any unintended modifications. This feature will significantly expedite the building process and encourage more experimentation and creativity. Stay tuned for more updates and exciting developments on the way to our Summer 2023 Launch.Read full article on Community Announcements (ST Official)
