Need help with a brushed bronze texture

Jet_Pilot

I'm trying to make a brushed bronze texture for a prop I'm messing around with, but the problem is i want the brushed to follow a curve. my current technique was to add noise then motion blur it. That game me good results on like 80% of the prop, but places where the mesh curves it looks REALLY bad. Anyone have a good technique.



P.S. re-uving is NOT an option

Calabi

I'm no expert but my guess with something like this is the best way would be to set up the material in a render software then bake it on to the uv.

Blaisoid

you can try adding radial blur on circular areas instead of motion blur. i used that once for brushed metal and result was ok.

Selaznog

Well what I would do is set the UVs for the shape so they're in a straight line. You might get a bit of stretching, but in the end it will be way easier to texture it.


EDIT: Just saw that re-uving is not an option. What a shame. Disregard my post and good luck :P

yeah - do what selaznog and luke/calabi are saying - get yourself second set of UV's (say map channel 2 - dont worry - these are only temporary - in the end you'll be using your original set of UV's) -> get that big round element straightened out (so it looks like rectangle with all loops and rings going horizontal/vertical - you can do it in max's unwrap no problem with little or nothing tweaking required but don't have it handy and can't remember how that button is called

then create texture like the one above - with straight lines (can be black and white only - it's only the directional lines that we want - apply to you geo - make sure to change map channel in mat-editor to 2 - then bake out your colour to new map - using map channel 1 - you should get nice brushed effect following curvature of your element

it seems far fetched walk-around - but i dont think you have to do it for every single bit of your map - just the most prominent and should be ok

cheers and good luck

You could also select a copy of the texture and then use the warp function to bend the lines into that shape. It's probably more work than baking it into a second UV set however.

i used the UV2 method and got exactly what i wanted... POLYCOUNT FTW!

Thanks
