3D Artist - - TOP TRICKS FOR HOUDINI 17 -

01 The main forms – Guide Ad­vect I usu­ally cre­ate ba­sic forms us­ing Guide Ad­vect. Us­ing var­i­ous op­tions for the ad­vec­tion oper­a­tion and ap­ply­ing var­i­ous ge­ome­tries to the fourth in­put, you can very quickly cre­ate the ba­sic shape of the hair­style. I first used the ad­vec­tion oper­a­tion Con­strained Ad­vec­tion to prop­erly di­rect all the lit­tle hairs along the sur­face of the body.

02 Mane proxy ge­om­e­try Us­ing mod­el­ling tools, I cre­ated proxy ge­om­e­try for the mane. Houdini pro­vides many tools for this (eg Topobuild, Polyex­trude, Boolean, Edit). To more eas­ier ma­nip­u­late the guides, I cre­ated in­di­vid­ual proxy ge­om­e­try. Then, I put sev­eral Guide Ad­vects with Fill Col­li­sion Field and in­cluded Out­put Group of Af­fected Prim­i­tives.

03 re­fine­ment and ran­domi­sa­tion Now us­ing the groups that I cre­ated in Guide Ad­vect, I can re­fine the shape of the mane by edit­ing each part sep­a­rately. For this, I used Guide Groom by al­ter­nately switch­ing be­tween prim­i­tive groups in the Ini­tial Setup Prim­i­tive Group. Then I used Hair Clump to make clumps and curl­ing. I used the Guide Mask for masks and the Guide Process for ran­domi­sa­tion of length, bend, frizz and so on.

04 Don’t be afraid to ex­per­i­ment This is the main set of op­er­a­tors that I made use of to cre­ate guides for the lion’s mane. Of course, you can do it in a com­pletely dif­fer­ent way. Do not be afraid to ex­per­i­ment. This is the beauty of Houdini. It gives you a lim­it­less amount of pos­si­bil­i­ties for your imag­i­na­tion. Ad­di­tion­ally, the knowl­edge of other ar­eas in Houdini and VEX will ex­pand your po­ten­tial in groom­ing.
