Differential D5110
WIP: Draw Manager Compositing Alpha Under Authored by Jeroen Bakker (jbakker) on Jun 21 2019, 10:50 AM.
Details
This is the diff that was used to test a better alpha under compositing. It does not work as currently the draw engines do not keep the actual alpha values. Related to T65988: When rendering in viewport mode the draw engines do not pass correct Alpha values.
Diff Detail
Event TimelineComment Actions Does this really need another framebuffer? I would expect it's possible to draw alpha under without that kind of memory or performance overhead, by using different blend modes. Comment Actions There is DRW_STATE_BLEND_ALPHA_UNDER_PREMUL for that purpose but we can add a non premul if you need. |
