GL_INVALID_FRAMEBUFFER_OPERATION: Framebuffer is not complete or incompatible with command

Question

i have made a 360 image viewer on unity and i am changing image texture dynamically using c# script, so its work fine on PC unity but when i run it on android device it say error below:

OPENGL NATIVE PLUG-IN ERROR: GL_INVALID_FRAMEBUFFER_OPERATION: Framebuffer is not complete or incompatible with command

My code below

 IEnumerator registerFunc(WWW www)
{
    yield return www;
    if (www.error == null)
  //if(true)
    {
        Debug.Log("OK - CountTime");
        texturas = www.texture;
        www.Dispose();
        www = null;

       sphereMS.material.mainTexture = texturas;// here i am getting error
    }
    else
    {
        Debug.Log("ERROR");
    }
}

So any one can help me out in this how i can solve it.Thanks!

Answer 1

resolution is 9999x2429 and sphereMS is public variable to which i have assigned sphere using drag and drop

That's the problem. 9999 is really big. The limit on most Android devices is about 2048. Anything above this is a problem unless you are running this on very high end and expensive Android device.

One thing to try is replace

texturas = www.texture; 

with

texturas = new Texture2D(4, 4);
texturas.LoadImage(www.bytes);

The LoadImage function is used to load jpg/png image into a Texture. It might fail too due to the size of the image.

---

If LoadImage fails too then you should have different Texture resolution for each platform on your server. The Android platform should request for a lower resolution version of your Textures. Just keep reducing the Textures resolution until it stops crashing. 2048 resolution should be fine.

I suggest you read this post about texture size limit in Unity.

EDIT:

If you have changed the resolution to below 2048 and the problem is still there then this is a bug.

Install Unity 2017.2.0p1 or 2017.3.0b3 to get the fix. Few people experience this with the google-cardboard plugin.

Answer 2

Mostly it happens on Android devices using Mali GPU, even Asphalt 8 couldn't run on these devices (at least old ones).

I tried on Huawei Mate 10 and Samsung Galaxy A50s, as both are using Mali-G72 MP12 and MP3 respectively so getting the same error and the image gets black/blank (couldn't render).

While same works fine on other Android and iOS devices

Answer 3

use parametre

-disable-gpu  

or

app.disableHardwareAcceleration()
