Substances are generating too long

Hello,

Don’t know if my computer is so slow or i can’t configure substanes correctly but they are generating 2 times longer then loading my scene.
Dependent on the substance complexity it takes up to 20 seconds with 6 variations of 1 substance.
I’ve made a test scene with 2 substances of metal and bricks with color variations = 5 different materials.

For me it takes too long, is it known issue or i am doing sth wrong ?
Thank for reply.
Bye.

Your test scene generates in about 3 seconds on my MacBook, what are your specs ?
It still seems long as its only variations of the same texture, it should be very fast.
Could you send me a link to your test scene project by PM ?
