Vinyl 12" record shader

#1

Dear Forumers,

I am currently attempting to make a vinyl 12" record shader with an MIA MATERIAL X PASSES shader and am struggling.

I have the UVs as a chessboard pattern on the record and many very thin concentric circles piped into the bump channel. I have slightly warped the record with a bend deformer, and have the label of the record and the colour piped into diffuse channel, and something piped into reflectivity to make the different levels of reflection for the record label, the bit with the grooves (where the concentric circles are bumped) and the shinier bit inbetween these and at the edges.

Anisotropy is set to 10 too. The decks are meant to be outside and I have an IBL setup with a directional light emitting just specular to be the sun (it was an overcastish day).

Problem is it looks TERRIBLE :frowning:

Any help would be much appreciated.

Thanks,

Nick.

You can probably do this more easily by mapping in the specular channel instead of the bump. That will render faster, with more flexibility and less aliasing noise. Start with plain anisotropy, if that looks too plain and smooth, then add some groove texture to the spec. What I’ve done for brushed metal is use a very large map (4k) of a noise texture with a photoshop Radial Blur done on it several times. Unless you get close to the record surface you probably don’t need an actual ‘groove’ texture.

thanks. this is what my work mate was suggesting, makes sense. gunna try.

Unfortuantely this did not work so I am going for using a physically realistic bump, ie. the actual groove of a record. Hope it works.
