Finally finished the chess set. Had a lot of problems with the knight, followed the rule 80/20 and left some vertices with triangles still.
I am not sure but think something in the rendering is missing - seems some of the light settings making figures more 2d like, especially for white figures. If someone knows how to fix, please let me know. currently I have a sun set to 0.8 and hemi to 0.2. The figures have diffuse intensity to 0.8, and specular 0.2.
And most time whatever I do makes either too dark or too lightened :((
