- Fresnel V4.0
Based on feedback (thnx phase!) I found a big disadvantage of the 'real'
fresnel formula. It doesnt degrade to 0.0, causing 2-3 times too many
rays being fired compared to the previous one. So; a lot slower.
Now committed is a hybrid which allows (close to) real, and nice artistic
freedom, *and* it really goes to 0.0 and 1.0, assisting nicely in optimal
render times.
A real doc how it works (with pics) will be made before real release.
- Fixed bug in raytrace: the first renderpass didn't use fresnel for mirror.
- Fixed bug in previewrender, now it closer matches how fresnel renders
