Hey RyanB thanks you, after search in the network about that function i find this 3D Modeling & Texturing: [UE4 Quick Tip] Removing Frac Artifacts looks like your node but with the use of the 2 uv and now this work for me without cracks ^.^ this is okay ?
The only problem is change now the tileset texture because i can’t change that from the instance material but its okay
Thanks your your help!
