CreateScreenshot is not working on V3

[hit2501]

Hi, to make screenshots of a render canvas I used:

BABYLON.Tools.CreateScreenshot(engine, camera, { precision: 2 });

And it was working fine until I changed to V3 of Babylon, is there a way I can make it work?

jit you cancheck it on a work in progress: http://10foldfurniture.com/webgl/

Thanks

I think you just need to set preserveDrawingBuffer to true when creating the engine, i.e.

new BABYLON.Engine(canvas, true, {preserveDrawingBuffer: true});

Thanks Sable, I tried but nothing happens

Does this pg work for you?

If not, it could be that the browser you are using both doesn't support download on the a tag, and is blocking the opening of a new window to show the rendered image.

Thanks yes, it worked in your playground but no in my project, do you know what could be my problem?

In your project, does it download a blank screenshot, or just do nothing at all?

Your WIP site you posted above for me atm downloads a blank screenshot when clicking the render view button, which is because the engine doesn't have preserveDrawingBuffer set (as above).

Blank screenshot, just in case when I downloaded your sample didnt work either.

Strange thing, I put preserveDrawingBuffer as true but the error continues. Maybe is my error, please can you tell my where I must put the "preserveDrawingBuffer" line? (Im a noob :P)

Also, do you think this happens with old versions of babylon?

Try changing

window.engine = new BABYLON.Engine(canvas_model, true);

to

window.engine = new BABYLON.Engine(canvas_model, true, {preserveDrawingBuffer: true});

Sir, I love you, now works perfect, I'm still learning and sometimes (a lot) I fail

No problem, glad I could help.
