I using blender 3.6, principled bsdf, and a texture as base color. When I export to “dae” file, I want that it contains phong mapping into “technique” inside “effect”, not lambert. The specular value is set to 0.5 in shader, but dont show into collada file exported. I want my file like this:
<library_effects>
<effect id="effect_Blue">
<profile_COMMON>
<technique sid="common">
<phong>
<ambient>
<color>0 0 0 1</color>
</ambient>
<diffuse>
<color>0.137255 0.403922 0.870588 1</color>
</diffuse>
<specular>
<color>0.5 0.5 0.5 1</color>
</specular>
<shininess>
<float>16</float>
</shininess>
<transparent opaque="A_ONE">
<color>0 0 0 1</color>
</transparent>
<transparency>
<float>1</float>
</transparency>
<index_of_refraction>
<float>1</float>
</index_of_refraction>
</phong>
</technique>
</profile_COMMON>
</effect>
</library_effects>
But my collada file aways return
<technique sid="common">
<lambert>
<emission>
<color sid="emission">0 0 0 1</color>
</emission>
<diffuse>
<texture texture="human_texture-sampler" texcoord="UVMap"/>
</diffuse>
<index_of_refraction>
<float sid="ior">1.45</float>
</index_of_refraction>
</lambert>
</technique>
