Looking inside the sfa dele we have some configurations.
One of then is the metallicFactor
On the Google I/O Video about Sceneform it's say that it can go from 0 to 255 and we normally should use from 0 to 1.
My first question, on the code we should use: 0, 0.2, 0.4, 1 or 0, 20, 40, 255?
Second, using one of the Sceneform Sample for Android I try to change this values for the Sun in the "solarSystem" sample. But for any go the changes it looks the same. What I'm missing?
Someone has a example from the minimum value to the maximum value to see how it should look (Only changing the metallic factor. without change roughness)?
metallicFactorscales metallicRoughness to control the metallicity of the material:
metallicFactor <float_value>
Use 0.0 for non-metallic materials:
metallicFactor: 0.0;
Use 1.0 for metallic materials:
metallicFactor: 1.0; // Normalised 1.0 is similar to 255 in 8-bit color scale
So in the code we need to use:
0.0,0.2,0.4and1.0respectively.
Hope this helps.
