Still very new to the usd and solaris. I try to overwrite the basecolor for redshift when instancing them to points. For karma is call basecolor. I check the usda file of the redshift materials and the name is call diffuse_color, but it doesn't seems to work. After some mess around, i use editmaterial after intance and read the attributes to the material, and it works find. Anyone knows why? The data seems go through but not get overwrited. Test file attached.
