IntroductionHi,mynameisMassimoRighiandIamfreelanceCGartistfromItaly.
WhatI'mgoingtodo,istotryandshowyouthemainstepsofhowI'vemademy"MaleGreenFrog"image.I'veusedMaya8formodelling,MentalRayforrenderingandPhotoshopforthetextures.
Thegoalformewastonotonlycreateaphoto‐realisticrender,butalsoa3dmodelforanimationpurposes,withouttheuseofZBrush(orsimilarsoftware)andwithoutaddinganykindofpost‐worktothefinalrender.
Thefirstthingwastodosomeresearchtofindsomegoodreferences,havinginmindthefinalresultIwantedtoachieve.Iwasn'tabletofindalltheviewsofthesamefrogthatIwanted,soImixedalotofdifferentfrogsinordertomodelthemainshape.
I'vestartedbuildingthelow‐polyfrogusingasimplepolygonplaneandI'veextrudedtheedgesfollowingthereferencepics.I'vethenmodelledthemainbodyleavingholeswherethelegsareconnected.
Afterthat,Icreatedthelegsandthenjoinedthemtothebody.
AsyoucanseefromtheWIPpicbelow,I'vebuiltonlyhalfofthefrogsothatIhadonlyhalfoftheUVmaptodealwith.
Oncehappywiththelowpolymodel,itwasthetimetomaketheUVmap.
Forthemain(half)bodyandtheleg,I'vemade2cylindricalmaps,forthefeetI'veused2planarmaps:1fromthetopviewandonefrombottomview.I'veusedasimplecheckerappliedtoalambertshaderforcheckingtheoverallprocesswhiletweakingtheUV's.
AfterthatI'veduplicatedthehalfandcombinedallendingupwith1.960polygons,quitegoodforthelowpolymodel(thisthencanbeusedasacagefortherigging/animationprocess).
I'vethanduplicatedthefrogkeepingthelowmodelinanotherlayer,andI'vemadethehigherpolyversion(about30.000poly)doingapolysmooth.FinallyI'veaddedsomedetailsusingtheMayasculptingtoolstryingalwaystofollowthemainreference.
Usingphotosandfreehand(I'veusedaWacomtablet)I'vemadethetexturesinPhotoshopeach2048x2048.I'veappliedthetexturetothefrogbutI'venoticed(Iwasexpectingthat:P)thatsomeofthetexturesseamsneededtobeadjusted.I'veusedthebuilt‐inmaya3dpaintforthat,usingtheclonetool.
WhenthecolortexturewasmadeI'vecreatedthespecular,bumpanddiffusemapfromthat.
Nowwasthetimeforsettingupthescene.I'vecreatedasimpleplanewhereIplacedthefrogandI'verotateditabout17°(I'vedonethatforthefrogtoo).FortheplanetextureI'veusedaphotomadebyme,I'vecroppeditabout1300x900,I'vethanmadethebump.
I'vecreatedacameraandI'veenabledthedepthoffieldonit.AsyoucanseefromthegrabI'vemadeadistancetoolplacingonelocatorinthepointoffocusonthemodelandtheotherlocatorinthecameralens.I'vethanparentedthatlocatortothecamerasothatwhenIwasmovingthecameraalsothedimensionvaluewaschanging.
BeforeworkingonlightingI'vemadetheshadernetworks,oneforthemainfrogandonefortheeyeballs.AftersomerendertestI'vedecidedtouseforbothcasesablinnshaderwithaTranslucencevalue=1.
ForthelightingsetupI'veusedanHDRIprobeand3lights:1point‐light(raytraceshadow)and2spotlights.
FortheMentalRayrendersettingsI'veusedamitchellfilterwithasamplelevelmin=1max=3,RaytracingandFinal‐Gather.
Hereisthefinalrenderofthefrog.
