Initial Model of the Candle

| Reference Image to 3d Render | ||

Initially, I used a normal ramp texture on a blinn hoping that it will create the illusion of subsurface, however it just looks flate. So I decided to look up tutorials on sub-surface scatter for mental ray and try to apply it to the candle. Below you will see the process. Images are clickable for larger version. |

This is my second try on the flame Animation. I used the dynamic spline method . Creating a spline IK, I converted the spline into a dynamic curve which reacts to dynamic field. Click here to see larger version

Prof. Melcolm provided a RenderMan Translucent Shader for the wax, which I applied onto it. Click here to see the Shader Language. Below is the result of the Shader.

On the left you can see the network of the wax shader. I have also added a displacement to the shader to give it some roughness. What I don't really like is the bottom part of the shader that i cannot get the correct color, as it is affected by light. If I have time i will go in and play around with it again. |
