How do I add a real-time reflection to a mesh that was created in blender.

Recommended Posts

Hello Everyone,

 

I would like to add shadows and reflections to a car model that was exported from blender to Babylon.JS. (The file is attached to this post.) I have tried using 'static reflection' in the blender software but it looks horrible when I exported it as a *.babylon file. I have seen reflections in 'The Car" demo on the BabylonJS website and would like to know how to do the same. I am not sure how to identify the mesh that I want to use as a reflector (My programming skills is very weak.) I have seen the tutorial on 'advanced texturing' here https://github.com/BabylonJS/Babylon.js/wiki/14-Advanced-Texturing, but I am not clear on how to do it with *.babylon meshes.  Could someone help me please? I would greatly appreciate it. Thanks

You can use LensFlare to create reflections. See here:

 

var lensFlareSystem = new BABYLON.LensFlareSystem("lensFlareSystem", light0, scene);

var flare00 = new BABYLON.LensFlare(0.2, 0, new BABYLON.Color3(1, 1, 1), "Assets/lens5.png", lensFlareSystem);

 

https://github.com/BabylonJS/Babylon.js/wiki/How-to-use-lens-flares

 

You can also play with the lights on the specularColor and emissiveColor level.

 

and you can also use the reflexionTexture

 

var material = new BABYLON.StandardMaterial("name", scene);
material.reflexionTexture =
new BABYLON.Texture("reflexion.jpg", scene);
material.emissiveColor =
new BABYLON.Color3(0.3, 0.3, 0.3);

Hello Dad72

 

Thanks for taking the time out to assist me. My car.babylon file contains several meshes and I would like to make the the body, doors and rim meshes to be reflective. I need to know how to identify and target these meshes so that I can add the reflection texture. I also need to know exactly where to put the code for the reflection texture. Do I add it to the html file or do I create a new javascript file e.g. 'car.js' and place the code in that file. All of this is beyond my present knowledge. Thanks for your help.
