Could you provide more details about the phone itself? Model, Android version, etc.

Does it happen when forcing GLES2 via project settings / command line, and running on desktop?

Calinou commented 5 years ago

@bojidar-bg As far as I know, glow isn't implemented in the GLES2 renderer.

grenzionky commented 5 years ago

@YeldhamDev I updated the question

grenzionky commented 5 years ago

Gles2 doesn't give a glow option to begin with

akien-mga commented 5 years ago

I can confirm that using GLES3 + Enviroment Background Mode "Canvas", glow doesn't work on Android.

Glow is now implemented in GLES2, but bg_mode Canvas is outright broken on GLES2, so this issue is specific to GLES3. The GLES2 issue is tracked in #32458.

This is likely because Android defaults to "3D-no effects". You need to change the render setting Frambuffer_allocation.mobile to "3D". http://docs.godotengine.org/en/latest/classes/class_projectsettings.html#class-projectsettings-property-rendering-quality-intended-usage-framebuffer-allocation-mobile

akien-mga commented 4 years ago

@clayjohn I just tried and that doesn't seem to be the case.

On Linux desktop with "3D Without Effects", 2D glow still works fine in GLES3.
On a GLES3-compatible Android device (Xiaomi Pocophone F1) with "3D", 2D glow still doesn't work.

BTW, even if it doesn't seem to be the full explanation here, it might still be a relevant factor. I feel we might need clearer documentation in a prominent place (and note:: references in other related places) to the framebuffer allocation options and their different default values on desktop and mobile.

I want to add this: With Godot 3.2 on Windows: If i turn on Background Mode "Canvas" in GLES3, all the viewports fail to render transparency, and renders black instead, even if "Transparent Bg" is enabled.

I am having this problem basically for be glow is working on gles3 (2d canvas mode) but while using addictive blend mode it is getting weird flickers and is getting a blueish cast on the whole screen

I was having this issue in the 3.x branch, however doing this made it work on a Huawei Nova 5T with Android 10 and the Android Studio emulators

akien-mga commented 2 years ago

Fixed by #58470.
