Hello @chafik_unity , when using Recorder to capture set of *.png images with transparency background for further processing in videoediting sw, the areas influended by ambient occlusion (applied using post-processing stack) seem to be transparent too. Is it a known issue or should it be considered as a bug? To be specific: Win10, Unity 2018.3.b3, default empty scene, standard rendering pipeline (it means no LWRP or HDRP etc.). Skybox material removed; few boxes with default material, default light and camera. Apply Post-Processing stack 2.0.13, there apply Ambient Occlusion -> Scalable Ambient Obscurance. Use Recorder 1.0 installed from the Asset Store The results are in the attached pictures, as well as screenshots of camera and postprocessing settings plus recorder settins.
