Noooo :) You need to either increase the tiling on that checker, or create a grey bitmap and apply noise to it (making pixels visible). The overall density of your texels are very mismatched. This causes fillrate issues, aliasing/moire and other nasties. The UV's just need adjusting. The gauges need less UV space and the…
well, the easy eye-balling way is to throw a checker pattern on it and scale the UVs until the pattern is the same on everything. or if you modeled it to scale and your shooting for a 4 pixels per max unit scale (is that what Unreal 3 and the likes use now?) > box map it at 1/4 your texture size (then lay out the uvs)
OK boxmap a box per my previous instructions and apply your checker pattern to the box and your model. I don't know what it's called in maya but boxmapping is like a box made of planar maps. The main reasoning behind the box mapping method is to get a consistant pixel density across all assets in a project not just within…
