It's a fantastic design!

The texture tiles horribly because of the dirt which gives an obviously visible pattern, hardly usable that way.

I thought if you submit something to here, it should at least be usable in some way and no I'm not using substance designer, it is nice proprietary software.

I think "hardly usable" is overly picky. It has plenty of utility. True, it would be better if there were a more randomized set of rust patterns, but please find a less abrasive way to request improvements. Criticsm should constructive criticsm, not just a list of things you don't like.

I appreciate the contributions (both of) you have made, but the "I demand a refund!" attitude doesn't make sense on a free-asset-site powered entirely by the generosity of its users.

All you would need to do is view the texture tiling a few times, then the problem would become obvious to you, I don't make demands, I'm just pointing out the obvious problem with this.

I don't disagree with you about the problem, but you are being a jerk about it. Besides, this person is more than likely a beginner. You should encourage people so that they want to get better instead of trying to make them quit altogether.

So telling people about reality is being a jerk? I said what is wrong and encouraged him to make it better, I see no problem here.
