in this render i have not used a gradient or something as fac between transparency and SSS.i have tryed to find the mix,to have a base material what works at it is.
Hi wissammax,your new render looks good.dentin gradient, yes you are right,i was not sure how the real dentin color and gradient looks like.i have searched for reference fotos,but there are many different variations,and i havent found a complete real dentine without enamel.
i have to say, i have not connected any volume scatter, to the enamel or dentin,because the SSS are scattering enough for itself.it helps rendertime too,i can render it with GPU at around 3min.for backlight renderings volume scatter are better ofcourse.
Gradient in tooth color comes from the fact that enamel layer thickness differs between tooth parts , this diagram shows how we layer ceramic to mimic real teeth
do you have a dentin material ,for your tooth building ,underneath the crown & bridges then?or do you build it, like the last picture a ceramic with a color alone?
There is different methods to make crowns , pom (porcelain on metal) , inceram , pressed ceramic , zircon , all these types uses the same materials , except metal because it needs opaque material to hide metal color
Then we have opaque dentin & dentin & mamilon to make that things like fingers & enamel & high transparency enamel & effect enamel which comes tinted with blue or orang & we have occlusal dentin
All this can enter building operation , but the essentials is dentin & enamel
Yes I have dentin material & enamel material , I build this materials on the metal or zircon crown like the diagram I put , we use paint brush & water to build ceramic
thanks again ,for the link and the explanation.i am interested in the blue enamel color, or even better the specs of the material,like how translucency it is ect.do you paint the dentin with a gradient too?do you have maybe a pic from a complete painted dentin?
things thats unclear to me are, dentin color/variation/gradient or not ,and enamel color blue/orange? and its transparent/translucentcy and roughness(blurryness/milky).
indeed dentin is one color but I like to add gradient to increase color diffidence between tooth margin & cervical area , here is photo for ceramic on metal bridge
worked a bit on the gum,and added some translucency values from the papers to the teeth.i think thats it for now.maybe some more white opaqe enamel for younger teeth would be fitting,vs more dentin/stain look for older teeth.
that is a great locking gum , tooth material looks better and better by time , if you can change the light angle it will give better idea of materials because specular highlight is covering a big area of the surface , & you can mirror all objects to get tow teeth instead of one
