Combination without impact on image

[zonicek]

Hi,

 

please I have one problem.

I have 10 materials (color) and 10 ribbons (color)

 

I can assign every variation of materials and ribbons to single image (where is materials and ribbons)

 

But after that i have size and the size havent impact to image, but is there possible to remove size with impact to image?

 

For example:

Blue with green - i have image

And when i have 20 sizes - there is neccesery to create 20 variation and assign image?

Because If i select size (where i haven't create combination) i see all images.

 

Thank you.
