Why no aiGetMaterialTextureCount method is available?

[OsmanArjen]

if there is a aiGetMaterialTextureCount method in assimp it means that a material can hold different textures with the same type why there isnt that feature in russimp?

im new to it so i need to ask would it make any difference? do most of the 3d objects consist of only one texture per types?

the idea with russimp is not to provide the same interface but the same functionality lets say.

this is the method that you want

unsigned int aiGetMaterialTextureCount(const C_STRUCT aiMaterial *pMat, C_ENUM aiTextureType type) {
    ai_assert(pMat != nullptr);

    // Textures are always stored with ascending indices (ValidateDS provides a check, so we don't need to do it again)
    unsigned int max = 0;
    for (unsigned int i = 0; i < pMat->mNumProperties; ++i) {
        aiMaterialProperty *prop = pMat->mProperties[i];

        if (prop /* just a sanity check ... */
                && 0 == strcmp(prop->mKey.data, _AI_MATKEY_TEXTURE_BASE) && static_cast<aiTextureType>(prop->mSemantic) == type) {

            max = std::max(max, prop->mIndex + 1);
        }
    }
    return max;
}

I don't have access to my pc right now but I believe you can do something like the following. Pseudo code by the way.

scene.materials[your_material_index].properties.filter(|x| x.semantic.eq(TextureType::Diffuse)).collect().len()
