| Feb 22, 2019 at 21:22 | comment | added | Gez | Keep in mind that PNG uses unassociated (straight) alpha which does not cover the subtle transparency effects associated (premultiplied) allows. A clear glass or a bubbly reflect the environment with little to no occlussion of the background, therefor unassociated alpha won't produce a realistic effect. Considered the method described above as a hack: the holdout portion of the shader will occlude the light from the background layer, which is something that a bubble or a glass won't do in reality. | |

fix both broken documentation links with links to the current docs.

| Jun 11, 2016 at 22:07 | comment | added | gandalf3 | @Pow Not sure what you mean? What semi-transparency problem is there in the cycles viewport? | |
| Jun 11, 2016 at 21:39 | comment | added | Pow | is using the holdout shader going to correct the semi-transparency problem in cycles viewport? | |
