In early 2009, IDV discontinued the SpeedTreeMAX and SpeedTreeMAYA plugins, replacing them with SpeedTree Modeler and Compiler products. IDV eventually released plug-ins for Maya as well, appropriately named SpeedTreeMAYA. SpeedTreeMAX was released in February 2002, and toward the end of 2002, IDV released SpeedTreeRT, a real-time foliage/tree middleware SDK, which enables automatic levels of foliage detail, real-time wind effects, and combine lighting options.

Although backers pulled out of the golf project, IDV refined the CAD software as a 3D Studio Max plug-in for an animated architectural rendering, dubbing it SpeedTreeMAX. The initial explanation of SpeedTreeCAD CAD standing for ' computer-aided design' was developed by IDV for a real-time golf simulation. SpeedTree was conceptualized at IDV in circa 2000, and originated due to the firm's lack of satisfaction with 3rd-party tree-generation software on the market. SpeedTree was awarded a Scientific and Technical Academy Award in 2015, offered to IDV founders Michael Sechrest and Chris King, and Senior Engineer Greg Croft. SpeedTree has been used in more than 40 major films since its release in 2009, including Pandora, in Avatar.

SpeedTree has been licensed to developers of the range of video games for Microsoft Windows, and a Xbox and PlayStation console series since 2002. IDV that generates virtual foliage for animations, architecture and in real time for video games and demanding real time simulations.

If you have a customized billboard shader, depending on the previous behaviour you might need to amend your shaders.SpeedTree is a chain of vegetation programming & modeling software products developed as well as sold by Interactive Data Visualization, Inc. Refer to SpeedTreeBillboard.shader for the change.

Now a batch draws one type of billboard because in real world cases billboards can hardly share one batch.

Multiple cores are utilized for executing the dynamic batching code of billboards.īatching logic is simplified. Performance Improvements in 5.3īillboard batching performance is improved in 5.3. Known Issues: As with any other renderers, the receive shadows option has no effect while using deferred rendering, billboards will always receive shadows in deferred path. You can use BillboardRenderer.shadowCastingMode and BillboardRenderer.receiveShadows to alter these options at runtime. Trees painted on the terrain will inherit billboard shadow options from the prefab. To change billboard shadow options of instantiated SpeedTree game objects, select the _Billboard object in the Hierarchy window, and tweak these options in the Inspector of the Billboard Renderer, just as you would with a normal Mesh Renderer. spm asset, tick Cast Shadows or Receive Shadows in Billboard Options and hit Apply Prefab. To enable these options, select the Billboard LOD level in the Inspector of a.

To make billboards cast shadows correctly, during the shadow caster pass, billboards are rotated to face the light direction (or light position in the case of point light) instead of facing the camera.

How to make SpeedTree billboards that can cast and receive real-time shadows. But be aware that SpeedTree trees usually use 3–4 different materials, which results in a number of draw-calls being issued every frame, so you should try to avoid heavy use of LOD trees on platforms that are sensible to draw-call numbers. Additionally, terrain accepts any game object with an LODGroup component as a tree prototype, and put no limitation on the mesh size or number of materials being used (in contrast to the Tree Creator trees). The prefab can both be instantiated in a scene as a common prefab instance or be selected as a tree prototype on the terrain and paint massively. The SpeedTree importer in the end generates a prefab with LODGroup component configured. Materials will not be generated again on reimporting, unless you hit the Generate Materials or Apply & Generate Materials button, therefore any customisations to the materials can be preserved. SPM assets for you to tweak the generated game object and materials. There are import settings when you select. Make sure the textures are reachable in the project folder and materials for each LOD will be generated automatically. SpeedTree assets (.SPM files saved by Unity version of SpeedTree Modeler) are recognized and imported by Unity just like other assets.
