RUST AND DIRT ON METAL AND GLASS

you can save time and build up a li­brary of use­ful tools for fu­ture projects

3D Artist - - BOOST YOUR MARI SKILLS -

This project started with the need to find out how uvs re­act to dif­fer­ent mesh smooth­ing meth­ods but it quickly turned into a per­sonal project for me to work in Mari some more and bring my tex­tures into Arnold for vol­u­met­ric light­ing, ren­der­ing and com­posit­ing.

GIZMOS

i al­ways say that 70 to 80 per cent of any­thing can be au­to­mated – and so can tex­tur­ing. i pre­fer spend­ing a week on a lit­tle node that does a lot of work than do­ing the same thing over and over again. You will al­ways end up paint­ing for that fi­nal per­sonal touch but when dead­lines are tight, that lit­tle gizmo will be use­ful. Ex­port them and make your very own li­brary!

EX­TEN­SION PACK

i used Mari 3.2v1 with Ex­ten­sion Pack 4r1. This ex­ten­sion is cru­cial to my work­flow as it dras­ti­cally in­creases the ease and speed at which i work in Mari. in ad­di­tion to this, i re­ally like the sub­tle grunge tex­ture packs pro­vided by 3D Col­lec­tive. i am us­ing that in my Mari graph.

MESH SMOOTHINGI

This project started with the need to find out how uvs re­act to dif­fer­ent mesh smooth­ing meth­ods. How­ever, it quickly turned into a per­sonal project for me to work in Mari some more and bring my tex­tures into Arnold for vol­u­met­ric light­ing, ren­der­ing and com­posit­ing.

FULL CON­TROL

What i like so much about Mari is that you can build a ma­te­rial from the ground up. You are in full con­trol over what type of in­for­ma­tion goes into your Nor­mal, rough­ness or Dif­fuse. Wait, you need a three-layer pack­aged sub­sur­face scat­ter­ing mask for a char­ac­ter? Easy! if Mari doesn’t have the tools na­tively, EP will.

SHADERS

shaders in­side Mari are very use­ful to quickly look de­velop your ma­te­rial. For this project, i used the Ai­s­tan­dard to qual­ity check my tex­tures be­fore i started the lengthy ex­port­ing process. Be­ware of the height vari­a­tion pa­ram­e­ters, though – they’re more likely to crash the soft­ware than to show the neat end re­sult you’re look­ing for.

NODE GRAPH

i’m a big fan of the Node Graph and i au­thor all my ma­te­ri­als and tex­ture set­ups in this sys­tem. You can en­able it in your pref­er­ences but make sure you keep your graphs clear and com­mented. i like to use ra­dio Nodes to hide con­nec­tions, cre­ate Back­drops with names and i change the names of nodes to be able to re­vise older work.
