3D of GLES2 does not really work on Android devices with GLES2 GPU #20958

Closed avril-gh closed 6 years ago

avril-gh commented 6 years ago

Godot version: Godot 3.1 master branch at 2018-08-13

OS/device including version: Tested on Android 4.4.2 - MTK6592 - 1GB - GPU Mali 450 MP4 700Mhz - GL2.0 Android 4.4.2 - BCM23550 - 1GB - GPU VideoCore IV - GL2.0 (have fiew more devices like these but since errors are exacly same on those 2, then i assume that rest will be same) Note that Godot 2.1.5 works on these devices very well.

Issue description: 2D seems to work (not really tested yet since i mostly aim at 3D features. Just placed Label on screen to show FPS and its visible) 3D mode while on GLES2 GPU android device, shows only background (sky/ground color) and nothing more, no 3D objects are visible, and if more complex 3D objects are added it crashes after splash screen..

Most simple starting cube exported from blender are invisible on android and throws many errors

Attached Project with simple cube from blender test7.zip

The same project contain another object a little more complex (Cube.tscn), If you add it to scene, it will completly crash on android with GLES2 GPU after splash screen. CSG objects are invisible on android also if you try to place them for test.

Basicaly - no 3D objects are visible in 3D mode on android with GLES2 GPU

Steps to reproduce: Run example project (test7.zip attached above) on android device with GLES2 GPU

Minimal reproduction project:

This seems related to #20734.

Will take a look

karroffel commented 6 years ago

So the extension in CubemapFilterShaderGLES2 can be substituted for something that might work less good but at least it will run. That fix is easy to make.

The other problem is that your device doesn't seem to support depth textures, so renderbuffers have to be used (which are write only) with an additional color attachement to write to a shader-readable texture that can be used for shadows.

The first thing is an easy thing to fix, the second one might take some more, I'll work on it and report back!

@karroffel I took some info from android devices mentioned above in bug report, that might be helpful.

might be useful. crash log has been taken from Mali450 MP4 device. project used in test can be found in first post of this issue (test7.zip) in crash test Cube.tscn has been added to scene and simple cube has been hidden (Cube.tscn is included in project folder but not added to scene by default)

closing since it seems fixed at current time. (The objects are visible now, and error spam is gone)
