receiveShadows on mobile devise not working

Questions
1

I don’t know if this is a bug, but receiveShadows on mobile devise (Huawei Mate 10 Pro, Chrome 81.0.4044.138) not working, ground is not rendering.

https://playground.babylonjs.com/#SU7C7U#5

ground.receiveShadows = true; //Line 66
Not working

ground.receiveShadows = false; //Line 66
Working

Do you have any idea why this is the case. Do I need to change the phone :joy:

First question would be is your phone supporting WebGL2 ? cause Contact Shadows can only work in WebGL2.

Also what error can you see in the console ?

On a side note, I would not recommend contact shadows on phone if you do not want them to melt :slight_smile:

Your PG works only a single time, so you should remove the “var” in line 16 to make sure it is not the problem.

To know if it is a WebGL2 problem as @sebavan said, you should comment the line 58: this way, it won’t use any filtering method and so will work in WebGL1.

Yes, my phone is supporting WebGL2.
The are no errors in the console, its just not rendering mesh if receiveShadows=true.
And finally, commenting line 58, does nothing.
What can you guys suggest for me to get shadows working, so I do not melt my phone :slight_smile:

w00000t not relying on contact hardening shadows should definitely make it work. Also usually not rendering would mean the shader does not compile ending up as a console error. This is definitely strange and might be related to your phone drivers ?

Is there any other examples of shadows working on your phone ?

@sebavan ,

I cleared cash and line 58 does the trick. But the shadows don’t look great. How I can improve this?

So it definitely looks like a driver issue :frowning:

About improving you could try out other types of generator like esm blurred esm and so on ?

I will need to check everything through other mobile devices.
