In Flamingo nXt 5 (Windows), when we create a textured material, it is impossible to change the tile size. Regardless on what number we enter in the Tiles fields, the texture renders the same way.
This seems like a bug. I’ll add a report.
It seems like the material does update, but it’s not updating the object with the new material settings. The workaround is to change the object back to another material and then reassign the textured material to it. It should to update then.
