Phunzirani Mmene Mungaperekere Galasi Yoyenera Galama ndi Mia_Material_X
Choncho, muyenera kupereka galasi ku Maya ndipo simukudziwa kumene mungayambe. Ngati ndinu watsopano kwa Maya ndipo simukudziwa zambiri pogwiritsa ntchito plugin ya Mental Ray renderer , choyamba mungakhale mukugwira ntchito ya Blinn yoyenera ndikuphwanya poyera kufikira mutakhala bwino.
Izi zingagwire ntchito ngati choyimira chithunzi pamene mukuchotsa fano lanu, koma mithunzi ya mapulogalamu a Maya sangavomereze kumasulira molondola.
Kuti mupange galasi, muyenera kugwiritsa ntchito Mental Ray shader wodalirika wotchedwa mia_material_x .
Pezani Mia_Material_X
Mental Ray Mia shader ndi malo ogwiritsira ntchito malingaliro omwe ali ndi cholinga chokhala ndi njira yeniyeni yeniyeni yomwe mungaganizire kuphatikizapo chrome, miyala, matabwa, galasi, ndi tayi ya ceramic.
Node ya mia_material_x ikhale maziko a pafupifupi zinthu zonse zomwe mumamanga ku Maya, pokhapokha ndi mthunzi wa khungu.
Kuti mupeze mia_material_x, dinani mawindo a Hypershade > Mental Ray > Zida > mia_material_x .
MIA shader ndi mthunzi wosalowererapo.
Kusuntha Zolemba za Mia
Yambani chiyeso ndi chigawo choyambirira cha geometry ndi studio yosavuta kuunikira kuti mugwire ntchito yopanga magawo a Mental Ray.
Mia zakuthupi zili ndi zinthu zambiri zomwe mungasankhe. Zina mwa izo zidzakhala zofunika kwa inu, koma zambiri zomwe mungathe kuziiwala. Kufika pa galasi shader ndi chinthu chophweka-zinthu zimangoyamba kuyenda pamene mukufunikira kudzaza galasi ndi madzi.
Kupambana kwanu popereka galasi kumadalira momwe mumakhalira bwino magawo angapo: Kusokoneza, Kutsekemera, Kusinkhasinkha, Kuwonetsetsa, ndi Fresnel Effect.
Kutaya Parameter
Mukulenga galasi losaoneka bwino, loyera, kotero kuti ntchito yopezeka pa tabuyi ndi yosavuta. Kuwala kumapatsa mawonekedwe ake. Chifukwa galasi mu chitsanzo ichi ndiwonekeratu, simukusowa ziwonetsero zosiyana pakuwombera. Pansi pa tabu yowonjezera, sintha mtengo wa zolemera zolemera mpaka zero.
Kutsutsa
The Refraction tab ndi pamene mumagwiritsa ntchito magalasi omwe ali ofunika kwambiri.
Chinthu choyamba muyenera kusintha ndi ndondomeko ya refraction parameter, yomwe ikugwirizana ndi ndondomeko yeniyeni yowonongeka yomwe ilipo pa malo onse oonekera.
Ngati mumayang'ana pazithunzi za Index of Refraction tab, mndandanda wazing'ono zomwe zimagwiritsidwa ntchito pazinthu zosiyana zimatuluka. Madzi ali ndi ndondomeko yotsutsa pafupifupi 1.3. Galasi yamtengo wapatali ili ndi chenicheni cha refraction pafupifupi pafupifupi 1.52. Ikani ndondomeko ya refraction ku 1.52.
Chinthu chotsiriza chomwe mukufunikira kuti mugwirizane nacho ndizomwe mukuwonetsera . Mukulenga galasi shader yowonekera bwino, kotero yikani kuwonetsetsa kwa 1.
Kuganizira
Tsambalo lowonetsera limawonetsa kuti malo ambiri a galasi amawonetsedwa bwanji potsirizira pake. Ngakhale ziwonekeratu, galasi iyenera kukhala yochuluka kwambiri komanso yowonongeka.
Siyani kulemera kwa chiwerengero pa 1.0 ndikusintha reflectivity kukhala phindu pakati pa 0.8 ndi 1. Kugonjera pang'ono ndibwino kuno malinga ndi momwe mukufunira mu fano lanu lomaliza, koma mtengo wa reflectivity sayenera kutsika pansipa 0.8.
Zodziwika bwino
Ngati mutayesa kutembenuza panthawiyi, mudzawona kuti mukuyandikira kukhala ndi galasi looneka bwino, koma pali zida ziwiri zomwe muyenera kuzidziwa.
Ngati mukufanizira zotsatira zanu zamakono ndi galasi lachilengedwe chenicheni, mudzawona kuti panopa pangokhala wotanganidwa kwambiri kuti muthe kutchedwa kuti zenizeni. Pakalipano mia_material ikuwonetsa chilengedwe, chomwe chili chabwino, koma ikugwiritsanso ntchito ziwonetsero zooneka bwino zomwe ziri zolakwika.
Mfundo zazikuluzikulu ndizolemba kuchokera m'masiku oyambirira a CG pamene ziwonetsero zofiira zidayenera kukankhidwa. Ichi ndi chikhalidwe chofunikira mu CG ikugwera, koma pakali pano, ndikukupatsani zotsatira zochepa zomwe mungafune kuziwona. Mukufuna kusungirako chilengedwe chowonetserako koma mutaya zozizwitsa zokhudzana ndi zomwe zikuwonetseratu zomwe zikuwonetsedwa pano.
Pezani Balance Zenizeni zimakhala pansi pa Tsambali lapamwamba ndikuyiyika ku zero.
Zotsatira Zosangalatsa
Tsopano pamwamba pa galasi akuwonetseratu mofanana pamene kwenikweni muyenera kuona zofooka pamene galasi likuyang'ana kamera ndi zozizwitsa zowonjezereka kumbali yomwe galasi imatha. Izi zimatchedwa zotsatira za Fresnel.
Chifukwa chakuti zotsatira za Fresnel ndizochitika zofala, mia_material ali ndi chikhumbo cha Fresnel chomwe chinamangidwa mmenemo. Zonse zomwe muyenera kuchita ndizitembenuza.
Tsegulani kabuku ka BRDF (yochepa kwa Ntchito ya Bidirectional Reflectance Distribution) m'zinthu zakuthupi, ndipo onani bokosi lotchedwa Use Fresnel Reflection.
Muyenera kuwona zotsatira zotsatila pang'ono.
Kutsiliza
Mia_material_x ili ndi galasi loyendetsera galasi lotchedwa galasi lolimba lomwe liri pafupi ndi mthunzi umene umangopanga. Ndipotu, yayandikira kwambiri moti mwina ndi yabwino kwa zosowa zanu zambiri.
Nthawi zonse ndi zabwino kudziwa momwe chinachitidwira, ngakhale. Pogwiritsa ntchito kujambula nokha, mumaphunzira zomwe zimapangitsa kuti zikhale zosiyana siyana, ndipo mumatha kukonzanso zomwe mukuzifuna m'tsogolomu kapena kusintha zosiyana siyana.
Izi zikuti, ngati mukufuna kugwiritsa ntchito galasi loyendetsera galasi, ingotsegula malingaliro a mawindo a mia_material_x, gwirani batani lokonzedweratu kumtundu wakumanja wawindo ndikupita ku Galasi Yoyenda > Bwerezerani.
