i am trying to display texture in the viewport based on primitive attribute

i have tried material node with parameter override on ogl_tex1 parameter
it does not work
i also tried to create string attribute ogl_tex1 with file paths
does not work either
UV Quickshade cannot accept attribute variables
and creating texture attribute to override UV quickshade's Texture param gives me nothing

is there any way to make it work?

i do not want to render during tweaking, because i have to tweak the whole animation timing and composition which consists mainly of changing primitives with different textures

thanks for any info

To the best of my knowledge, per-primitive attribute override of the texture map is not supported in the viewport. The only way to achieve this is probably to have a different material per texture if that's feasible.
