Black screen on GLES2 #4

Closed cmrqs closed 3 years ago

cmrqs commented 3 years ago

Hello! I'm not sure if this is GLES3-only, but I get the following error using GLES2:

E 0:00:00.436 _copy_screen: Can't use screen texture copying in a render target configured without copy buffers. <C++ Error> Condition "storage->frame.current_rt->copy_screen_effect.color == 0" is true. <C++ Source> drivers/gles2/rasterizer_canvas_base_gles2.cpp:734 @ _copy_screen()

I just tried with a brand new GLES2 project and didn't experience any issue. Could you share your environment details?

Godot version
OS version
GPU model + driver version

Thanks!

Thanks for the quick response!

Godot version: Custom build 3.3.4 (also tested on 3.3.3-stable, same issue)
OS version: Coding in Arch Linux, exporting to Android 10 (also same issue)
GPU model + driver version: GeForce GTX 1650 (nvidia-dkms 470.74) | Adreno 630 OpenGL 3.2

As you can see in this image, it does work on editor, but I get this (both on Linux and Android) when executed.

Oh! So I found what's wrong. I had "Framebuffer Allocation" set as "2D without Sampling". When I changed to "2D" it worked :)

Maybe you should add this to README?
