Can I set the ambient property of a MeshPhongMaterial to false in a three.js imported Blender model? -

i'm doing pupil project , have scene ambient lite , spotlight. i've imported blender model has line:

"colorambient" : [0.6400000190734865, 0.6400000190734865, 0.6400000190734865],

in json file.

is there way turn off property in meshphongmaterial reacts spotlight , not ambient light.

i've tried removing line , setting 0 has had no effect. can turn property off? or should remove ambient lite scene , utilize different type such directional?

thanks help.

in practice, ambient reflectance of material should match material color, known diffuse reflectance. doing create model better.

for example, can this

material.ambient.copy( material.color );

or

material.ambient.set( 0xff0000 );

three.js r.67
