Candle Tutorial question - Polyloop

l3la · 11th March 2007, 22:47

Hi,

I was working on the candle tutorial which was a lot of fun so far. I have a couple of questions.

Here is the problem I am having: When I do the wick modelling I get quite a mess of extra polygons around the top - see the attached picture. I see that the tutorial leaves these as is. What are the best tutorials for figuring out how best to use this style of modelling - which tools support ngons, for example extrude seems to be highly affected by ngons.

I eventually got the SSS to work for me. I had to try the SSS on an isolated cylinder. A couple of days ago I did have the SSS working only using the instructions. Today I had to struggle since when I returned to the shading after the modeling settled down I had some SSS but it was not orange - it was a white glow. Is there a something in tutorial I could have missed because I had to mess around a lot more. I had to enable the fresnel effect to get a good balance of white light and color refraction for example. In the tutorial settings it doesn't show the Fresnel turned on but the online manual suggests using it.

I will upload the file here and a series of pictures that I hope might help.

Thanks for reading,

It is important to make sure Light through Transparency is turned on in render settings - this can either be in raytracing or Global Illumination. Here is a shot of the candle shader without this.

Here are 4 pictures showing that having Fresnel turned on makes more of a difference to realism than turning on GI.

The first here has neither Fresnel or GI.

The second has GI only. A better looking glow but not much coloration.

The third has only Fresnel at 65% and no GI.

The 4th has both Fresnel and GI.
