Recommended Posts

When adding a postProcess to the camera, the ScreenShot is black output. I remove prostProcess, the image is ok :

cameraPlayer.attachPostProcess(new BABYLON.FxaaPostProcess("fxaa", 1.0, this.cameraPlayer, BABYLON.Texture.BILINEAR_SAMPLINGMODE, engine, true));// OrcameraPlayer.__fxaa_cookie = new BABYLON.FxaaPostProcess("fxaa", 1.0, this.cameraPlayer, 2.0,  BABYLON.Texture.BILINEAR_SAMPLINGMODE, engine, false);var size = { precision: 0.5 };BABYLON.Tools.CreateScreenshot(engine, camera, size); // => return image black//*****************//cameraPlayer.attachPostProcess(new BABYLON.FxaaPostProcess("fxaa", 1.0, this.cameraPlayer, BABYLON.Texture.BILINEAR_SAMPLINGMODE, engine, true));// and//cameraPlayer.__fxaa_cookie = new BABYLON.FxaaPostProcess("fxaa", 1.0, this.cameraPlayer, 2.0,  BABYLON.Texture.BILINEAR_SAMPLINGMODE, engine, false);var size = { precision: 0.5 };BABYLON.Tools.CreateScreenshot(engine, camera, size); // => return image Ok

OMG I spent 2 hours trying to figure out why it was not working...

 

THIS IS A SIMPLE TYPO!!!!!! :)

camera.__fxaa_cookie = new BABYLON.FxaaPostProcess("fxaa", 1.0, camera, 2.0,  BABYLON.Texture.BILINEAR_SAMPLINGMODE, engine, false);

 

the 2.0 is a typo, you should call this:

camera.__fxaa_cookie = new BABYLON.FxaaPostProcess("fxaa", 1.0, camera,  BABYLON.Texture.BILINEAR_SAMPLINGMODE, engine, false);
