Render "GLES2" does not draw Polygon2D on Android

[Valeryn4]

godot 3.1.2-stable

Android 6.0 (BF166_BOOST3-SE_L010)

If you use the "GLES2" render, then the Polygon2D is not drawn!
If you use the "GLES3" render, then everything works
Textures imported as Loss

GLES2:

GLES3:

PS:
I need it for beautiful animations

[Valeryn4]

scenes that use Polygon2D produce the following errors:

Info that might be useful, what Android devices are you testing this on, and does it work when you try in 3.2? (Or just a simple test case for Polygon2D that exhibits the problem, not necessarily your whole project)

[akien-mga]

Could you try with Godot 3.2? This might have been fixed in that release.

I have not migrated to version 3.2 yet. Because it is necessary to rebuild all the templates.
In a couple of days I can check.

There is a problem on 3.2

To repeat the error you need: Cut a part of the texture using "Polygon 2D"

@Valeryn4 I wonder if the issue is caused by the texture and not by the Polygon2D. From the errors you reported it looks like you are using a unique type of texture.

Could you please try running the same scene with the texture removed to see if the issue is still present?

EXAMPLE PROJECT: https://github.com/Valeryn4/GodotPolygon2DBug

I am using PNG. Imported as "LOSS" or as "VRAM"
I found that this error is present only if "Skeleton2D" + "Polygon2D" is used

If you do not use Skeleton2D and do not deform the polygon, there is no such problem.

[Valeryn4]

There is no such problem on a PC.

Also, the "GLES3" render does not send the correct colors to some devices. If you use a polygon and a skeleton:

@Valeryn4 Thanks for the updates! I did a search through existing issues as well and it seems that using Skeleton2D with Polygon2D has many bugs right now. For example, your color bug is reported here #27919

Soon I will put together a big issue tracker so we can properly track all the Skeleton2D issues on GLES2. At this point it appears we need to do a lot of work to make it work properly.

[Valeryn4]

What is the alternative?
I have a lot of similar animation!: https://www.youtube.com/watch?v=4YfzkH1RHsg
It works well in GLES3, but does not work in GLES2

[clayjohn]

@Valeryn4 Unfortunately, I don't think there is an alternative right now. It seems that it is just broken. It needs to be fixed.

[Valeryn4]

Using the stable version, I expect everything to work there.
And it is not very pleasant to detect malfunctions at the end of development.

Why are there no warnings when using the Polygon or Skeleton that it does not work on some devices?

Such errors incur losses during development, and not a word about them in the documentation.
