Dzidza Maitiro Akutarisa Kuona Zvakakwana Girazi neMia_Material_X
Saka, unoda kupa girazi mumaya uye hauzive kuti unotanga kupi. Kana iwe uri mutsva kune Maya uye usine ruzivo rwakawanda uchishandisa plugin Mental Ray renderer , chido chako chekutanga chingangodaro kubata blinn yepamusoro yezvinhu uye kuvhara kuve pachena kusvikira zvanyatsojeka.
Izvi zvinogona kushanda semuongorori wekuona maonero apo iwe uri kudzivirira kunze kwemufananidzo wako, asi maMaya's shaders software haatombofananidzi pakugadzirisa kwakarurama kwepanyama.
Kuti ugadzire girazi, unofanirwa kushandisa shanduko yeMental Ray shader inonzi mia_material_x .
Tsvaga Mia_Material_X
Mental Ray's Mia shader inogadzirisa zvinhu zvose zvakagadzirirwa kuva chigadziro chakarurama chemuviri kune chero chinenge chiripo chepasi iwe unogona kufungidzira kusanganisira chrome, dombo, huni, girasi, uye tirayamu.
Mia_material_x node inofanira kuumba hwaro hwezvinhu zvose zvaunovaka muMaya, kunze kweganda.
Kuti uwane mia_material_x, chovha pawindo re Hypershade > Mental Ray > Zvinhu > mia_material_x .
Muenzaniso weMIA shader hauna maonero euthena ane tsanangudzo yakajeka.
Kugadzirisa zvinhu zveMia
Gadzira chiitiko chekuedza nechikamu chechiyero che geometry uye imwe soro studio inogadzirisa kuti ishande kuburikidza nekugadzirisa zviyero muMental Ray.
Iyo mia zvinhu zvine zvakawanda zvakasarudzwa zvingasarudzwa. Zvimwe zvacho zvichave zvakakosha kwamuri, asi zvakawanda zvaunogona kuzvicherechedza. Kusvika pane imwe girazi shader haisi nyore-zvinhu zvinongotanga kunetsa kana iwe uchida kuzadza girasi nemvura.
Kubudirira kwako mukugadzira girazi kunobva pakuti unogadzirisa zvakadini zvirongwa zvakasiyana-siyana: Kupararira, Kuratidzira, Kurangarira, Tsanangudzo, uye Fresnel Effect.
Parameter inopararira
Iwe uri kusika girazi risina ruvara, rakajeka, saka basa riri muDiffuse tab rinoshamisa zvakananga. Chiedza chinoparadzanisa chinopa chimiro chaicho chevara. Nokuti girazi iri mumuenzaniso uyu rakajeka, haunoda chero mafungiro akasiyana-siyana mumumvuri. Pasi pemutambo wakawandisa, shandura kukosha kwejeri rinorema kusvika zero.
Kugadziriswa
The Refraction tab ndiyo iyo iwe unobata nayo girazi rezvinhu zvekuisa pachena.
Chinhu chokutanga chaunoda kugadzirisa ndeye index ye refraction parameter, iyo inofananidzana ne-chaiyo chaiyo-yenhamba yenyika yekudzivisa tsika dzinowanikwa kune zvese zviri pachena.
Kana iwe uchikwira pamusoro pe Index of Refraction tab, shoma shoma yemafungiro emhando dzakasiyana-siyana dzinowedzera. Mvura ine chinyorwa chekudzivirira mukati kese 1.3. Crown girazi ine nyika chaiye-index ye refraction pa inenge 1.52. Isa rondedzero yekudzivisa ku 1.52.
Chinhu chokupedzisira chamunoda kuti tive nacho muchikwereti chetabhenji ndechekukosha kwekunzwisisa . Iwe uri kusika girazi rakazara girazi shader, saka sarudza kujeka kwehuwandu kune 1.
Kufungisisa
Pfungwa yekufungisisa inotarisa kuti nzvimbo yakawanda yegirazi inoratidzirwa sei muchirevo chekupedzisira. Kunyangwe kana zvakajeka, girazi rinofanira kuva nehuwandu hwekugwinya uye kuratidza.
Siya kubwinya kwechiedza pa 1.0 uye uchinje kugadzirisa kune imwe nzvimbo pakati pe 0.8 ne 1. Chidiki chekutendeseka chakanaka pano zvichienderana nechitarisiko chaunoda mumufananidzo wako wekupedzisira, asi kukosha kweflectivity hakufaniri kuderera pasi pe 0.8.
Specularity
Kana iwe ukaedza kujekesa panguva ino, uchaona kuti wava kuda kuva negirazi rinotarisa zvakanaka, asi pane zvimwe zvinhu zviviri zvaunoda kuziva nezvazvo.
Kana iwe uchienzanisa chiitiko chako chazvino ne girasi remukati-gasi, iwe uchaona kuti nzvimbo iri pari zvino yakanyanyisa zvikuru zvokuti inonzi yakakosha. Iye zvino mia_material iri kuratidza mamiriro ezvinhu, izvo zvakanaka, asiwo inoshandura mafungiro akajeka anobva pane zvinyorwa, izvo zvakaipa.
Zvinyorwa zvinotsanangurwa ndezvokuchengetedza kubva mumazuva apfuura eCG apo kufungidzika kwemaziso kunofanirwa kuputika. Icho chichiri chiitiko chinokosha muCG kubuda, asi munyaya ino, irikupa chikwata chaicho chaicho chaunoda kuona. Iwe unoda kuchengetedza nzvimbo yakaratidza asi iwe unorasikirwa nehukuru hunofanirwa-hunofanirwa huri kuonekwa panguva ino mumashanduro.
Tsvaga Bhuku Rinofananidza Balance hunofunga pasi peBhuku Rakawedzerwa uye rakariisa ku zero.
Fresnel Effect
Iye zvino pamusoro pegirazi rinoratidzika zvakafanana nekufungidzira apo chaizvoizvo iwe unofanira kuona zvisizvo zvisina kusimba apo girazi rinotarisana nekhamera uye zvakasimbiswa zvakasimba kumativi apo girazi rinovhara kure. Izvi zvinonzi Fresnel effect.
Nokuti chiitiko cheFresnel chinhu chinowanzoitika, mia_material ine chimiro cheFresnel chakavakwa mazviri. Zvose zvaunofanirwa kuita ndezvishandure.
Vhura BRDF tab (pfupi yeBhidirectional Reflectance Distribution Function) mune zvinyorwa zvayo mawindo, uye chengeta bhokisi rakanyorwa Shandisa Fresnel Reflection.
Iwe unofanirwa kuona kuchinja kwechigarire zvishoma.
Mhedziso
Iko mia_material_x ine girasi yekugadzira girazi inonzi girasi yakasimba iri pedyo neunenge wanyatsogadzira. Zvechokwadi, yava pedyo zvakakwana kuti zvinogona kunge zvakakwanira kune zvakawanda zvekuda kwenyu.
Nguva dzose zvakanaka kuti uzive kuti chimwe chinhu chakaitwa sei, zvakadaro. Nokugadzira kuvhara iwe pachako, unodzidza kuti zvii zvinokonzera kune zvakasiyana-siyana zvehumwe, uye naizvozvo iwe unokwanisa kukwanisa kubvisa shader kune zvaunofarira mune ramangwana kana kuumba kusiyanana kwaro kune zvakasiyana zvakasiyana.
Izvozvo zvakati, kana iwe uchida kushandisa girazi rekugadzira girazi, ingozarura firiji yemafurati ye mia_material_x, bata pasi bhatani rakagadziridzwa mukona yepamusoro yekona yewindo uye enda kuGirazi rakasimba> Shandura.
