We work on a realtime project, so keep attention to naming to later make easier the code manipulation.

On a complex scene, don't forget every tiny bits of optimisation could be important (non-exhaustive list): Optimisationįor this tutorial I will not going deeper in optimisation techniques, that's not the point so only minimum will be done. I will tweaking as most as I can on Blender scene directly, and once on BJS I will use the Inspector tool to refine things, and save this tweaks. But keep an eye on this editor, it's often updated.

It can be useful on small one-shot scenes, but in production mode you always have to tweak your scene between your modeler and your engine. babylon/.gltf scene file without loosing my editor tweakings. the 3D precomputed scene, dedicated to lightmaps rendering, with Cycles materials and lightsīabylonJS devs give us an editor, but for now it have some limitations for a daily use, specificaly the fact that I can't export and reexport my.the 3D realtime scene, which is the main production scene and from where the BJS scene is exported, with standards Blender Render materials.This forces me to use two scene versions: LightingĪs there isn''t raytracing engine inside BabylonJS, my lighting as to be made using a precomputed engine, like Cycles. Note that you can export as PBR using glTF format, this workflow is still experimental but usable, this may be a subject for a next tutorial.

Plus knowing how to work with Standard workflow still could be useful if we target no-so-high-end user hardware (not everybody have the lastest smartphone). This come from the fact that the official Blender-to-BabylonJS exporter doesn't yet handle PBR material exporting. In this example I'm not using PBR workflow but Standard one. You should of course took a look on BabylonJS Babylon 101 and How to. I assume you already have these kinds of habits (non-exhaustive list): I will not dwell on modeling and texturing methodologies, which are the same no matter which engine you're using.

This article will use the excuse of a tiny scene to explain a simple workflow from Blender to BabylonJS, using lightmaps so as to tend to realistic lighting.
