Bug screenShot in 2.5

[Dad72]

Hi,

Tools.CreateScreenshotUsingRenderTarget() returns a texture with a download error. 
Tools.CreateScreenshot()  returns an error with a black texture.

This produces if I leave the camera as is is loading the scene. If I look at the sky, it works for one, but the other always has a black texture.

Have same problem as @Dad72. I also get a totally black screenshot image using BJS v2.5

Unfortunately this is a Chrome security issue. It works on firefox and IE for isntance

[Dad72]

In fact I have the impression that it works when the camera is horizontal. If it looks down, it does not work anymore. This works with Chrome, but depending on the orientation of the camera. 

 Or another idea, the camera must look at an object. If there is only the sky, it does not work :

On the other hand, there is a new error now with document is undefined

Does it work on firefox for you?

[Dad72]

Yes, on Firfox is Ok.

And it seems to work with Chrome now.

@Deltakosh

It is not working to take screenshot any more with the v2.5!

I checked with v2.3 and v2.4 and there it works.

This is the code i use to take screenshots with.

BABYLON.Tools.CreateScreenshot(engine, scene.activeCamera,{width: canvas.width,height: canvas.height});

Edit:

@Dad72 command BABYLON.Tools.CreateScreenshot(engine, scene.activeCamera, { precision: 2 }); works however in v 2.5

   Edit again:

New PG:http://www.babylonjs-playground.com/#1WQSPX#6

BABYLON.Tools.CreateScreenshot(engine, scene.activeCamera, { precision: 1 }); DOES not work either!

Your PG works for me

I checked it on firefox, opera,firefox developer edition, IE and chrome on my developer computer and other computer.(all updated to latest version)

And it DOES work.(but not on my developer computer).

It is just me having some problem with firefox extensions on my developer computeri think.

I know this is an old topic, but after some times searching why my screenshot render was transparent, I found that you have to set the engine "preserveDrawingBuffer" to true to get it working.

This message is a reminder for myself and maybe help for people having the same issue

[Dad72]

I also noticed that "preserveDrawingBuffer: true" solve this problem. But why should we use that?

 

[GameMonetize]

preserveDrawingBuffer won't create a new buffer for every frame. And thus will keep the content as it is. Without it, every frame is filled with transparent color

[Dad72]

ok, I see.
