screenshot in multiple-projections-instancing example

[emrahkavlak]

hi marco,
thank you for creating the multi projection example! I'm a dirkkoy fan and when I found your example I got really excited.

I've got a question. When I use WebGLApp's screenshot function and change the size pixelratio to 10 (to get a large image), the resulting png is not correctly rendered. Some part disappears. Do you think this is a PNG issue or an angle / frustum / cam position issue? (FYI, if you make pixelratio 12, resulting png is 0)

here is an example

Hope this was an ok spot to ask this question.
Thanks,
emrah

I think you should not touch the pixel ratio, rather you should change the screenshot dimensions.
Try increasing the width and height like this:

webgl.saveScreenshot({ width: 4096, height: 2160 })

If you're still having issues on the screenshot feature, refer to ccapture.js, it's what the saveScreenshot function is using internally.
