I have a question how textures should be defined in COLLADA 1.5.
Here is a sample file portion:
<effect id="blinn3-fx">
<profile_COMMON>
<newparam sid="file2-sampler">
<sampler2D>
<instance_image url="#image-id" />
</sampler2D>
</newparam>
<technique sid="common">
<phong>
<emission>
<color>0 0 0 1</color>
</emission>
<ambient>
<color>0 0 0 1</color>
</ambient>
<diffuse>
<texture texture="file2-sampler" texcoord="TEX0"/>
</diffuse>
<specular>
<texture texture="file2-sampler" texcoord="TEX0"/>
</specular>
<shininess>
<float>0.3</float>
</shininess>
<reflective>
<color>0 0 0 1</color>
</reflective>
<reflectivity>
<float>0.5</float>
</reflectivity>
<transparent>
<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>
IMHO <instance_image> should be inside <sampler2D> as fx_sampler2D_type inherits fx_sampler_type which uses instance_image_type for a <instance_image> child element.
But the above XML does not validate with several tools:
- libxml
- apache xerces
- altova xml spy
xml spy gives me following error message:
Please tell me how to define textures in 1.5 !
