How to detect that state->text_list[0] has been filed

[Victor.Feliz]

If you try to export tex_list[0] as color obviously if tex_list is not filled some garbage is shown instead the proper values.

My intention is that if tex_list[0] hasn't be filled it returns pure grey.

Thanks in advance.

Perhaps you could use the mi_query for miQ_NUM_TEXTURES which returns the number of textures in state->tex_list

[Victor.Feliz]

It works

miInteger num_textures;
miBoolean texquery = mi_query(miQ_NUM_TEXTURES, state, miNULLTAG, &num_textures);
if (num_textures!=0)
{
//Make cool things
}
