Summary	0000012: Transparency Problems (f.e. TTextLayer3D transparency artifacts)
Description	Using a TTextLayer3D in FMX leads to problems with transparency when overlaying multiple objecs.
Additional Information	In general FMX uses a simple (and bad) sorting algorithm for rendering transparent objects. With 0.8.1 we implemented Weighted-Blended-Order-Independent-Transparency rendering in Gorilla3D. This lead to a massive refactoring inside the rendering pipeline. We had to implement a pre-version of deferred rendering more early, than we expected. At the moment rendering without render-passes works. In next days we'll fix render-pass handling and getting ready for release.

administrator 2020-01-20 08:13 administrator ~0000046	Rendering pipeline for Windows and Android GLES v3+ was fixed to support WBOIT (Weighted Blended Order-Independent Transparency) There is still a bug on using WBOIT in render passes like reflection and refraction (not rendered correctly)
