Hey guys, I have a bunch of planes on a copy sop and I need all of them to be always "looking at" the camera. I found this topic at sidefx' forum showing how to make it at sop level (I know, at obj level it's quite easy ), but I couldn't make it work. This is what they did there: I actually don't know what to put at the "lookat_path". How can I put a path to another object, like a camera, in there? Thank's Alvaro
hyperforce posted a topic in Finished WorkThis procedural level design tool is the result of my graduation project and my dissertation study into: “The rules behind a procedural death match map generator”. This project earned me a 10 and allowed me to graduate Cum Laude (with distinction) from the University of Applied Sciences in Breda. It earned me the title of Bachelor of Engineering in Game Architecture & Design. This Thread has been updated following the completion of my Graduation project. This tool is designed to create fully playable complex 3D combat arena's for the Unreal Development Kit, with minimal user / designer input. But without taking away control. It allows for rapid iteration and testing, using a user-mediated construction method. With this tool, a level designer becomes a digital director. The generator constructs levels following the death match game-type rule sets of Unreal Tournament 3 and the UDK, discovered during my dissertation ( Specifically "Axon" faction levels). It is capable of creating fully traverse-able, multi-leveled, interior 'white-boxed' maps. Including path nodes, player starts, logically distributed pickups and decorative meshes. Think of it as a 3D sketch pad for level designers, where the results can be immediately play-tested. The tool is fully procedural, and the results can be exported directly to the UDK using the .OBJ and .T3D file formats. The generator is highly modular and can be expanded and adjusted easily to support other game-types or games. Many components of the generator have also been improved over the course of my graduation period. The user interface and workflow have been significantly tightened and are now easier to use. It features 3 levels of control, ranging from highly automated to deep manual control. When using only random results and manual overrides, the tool can be used to rapidly browse through and tweak possible level layouts in order to quickly prototype unique levels. While using manual input allows for deep and detailed control over every part of the process. A designer can have as much control over the final result as he/she wishes. The tool uses a user-mediated approach to procedural level construction, meaning that it requires a designer to determine the shape and layout of a level he/she wishes to create. The actual construction of said level however is fully automated. How it works: The tool is mainly based on volume conversion (Houdini's Voxels) and constructs a level according to a 3D grid. After the main landmark spaces are generated, corridor profile curves are established between them using a path finding algorithm written specifically for this generator by Leroy Sikkes. Following this, the corridors are assembled from a series of components by analyzing the profile curves. Where corridors interconnect, minor rooms are generated. Finally, the combined level mesh is processed to form an internal grid, which is used to create catwalks and ramps. The finished level mesh is automatically UV'd to identify different area's and the mesh is optimized. Various objects can be automatically or manually placed throughout the level. These objects by default will always try to ensure the spaces they are placed in remain traverse-able. Place-able objects include: pillars, columns, low cover objects, box stacks & railings. Next a path grid is generated throughout the level for AI navigation and pickup placement. This is done in layers, each representing a different form of player navigation. Using these layers and the level geometry, each point in the grid is analysed and compared to the rest of the level for the following data: Exposure, Space to move, Distance to Walls, Height advantage & Reach-ability. This data is used to calculate the risk or tactical value of each point on the grid. A designer can then designate a series of hot-spots. These hot-spots are locations that the designers wants to attract players towards. This can also be done automatically if so desired. A designer can let the tool create a random pickup load-out for the level, or specify his/her own pickups. Each pickup definition in the load-out menu as well as each pickup archetype has its own placement rules. Based on the pickups placement definitions, the risk grid and hot-spots in the level; pickups are logically distributed throughout the level. During the final step, the level geometry is subdivided and cleaned. The size of each segment is calculated and a series of meshes are assigned to their respective surface. All a designer has to do to play the level is export it from Houdini using the OBJ and T3D format & import the files into the UDK and build the pathing. This can be done in less than 5 minutes. The .T3D exporter used in Houdini is currently under development by Jan Pijpers.

It employs a user-mediated approach, meaning that it requires a designer to determine the shape and layout of the level he/she wishes to create. The actual construction of said level however is automated. Randomized results can be used (to quickly explore possible solutions) during many of the steps in the process, but it is by no means required. A designer can have as much control over the final result as he/she wishes. Simply put: this tool enables a designer to rapidly prototype a level from the idea stage, to a play-testable stage, within only a fraction of the time it would have otherwise taken him/her. This procedural level design tool has several interesting utilities. Primarily, it is a tool that allows for the rapid generation of white box quality death match levels. Using it, a designer can quickly “sketch” out a level, make adjustment and play-test the result within only a fraction of the time it would have taken using a manual process. Secondly, with further polish and development, a generator such as this prototype could be integrated into a first or third person shooter. This could allow players to create their own combat arena’s without the need for complicated level editing software or level design experience. Furthermore, players could share their levels online, and download the best rated levels from other players, allowing for a nearly unlimited supply of levels and a longer game lifespan.
