Issue with DynamicTexture and canvas

[3Dlove]

Hello guys,

 

My example : http://www.babylonjs-playground.com/#1C4GCW#2

 

I have a little issue using a canvas in a texture :

 

1- why the transparency isn't applicated for the background color of my canvas ?

context1.fillStyle="rgba(240,240,240,0.5)";

alpha is 50%

 

2- why is show a grey part at right and bottom ?

yet, I used the good dimensions :

{width:rectSize.width, height:rectSize.height}

 

Thanks for your help :-)

Hello!

 

1. Only diffuseTexture can apply alpha testing

2. You have to ask the correct size of your dynamicTExture because due to WebGL restrictions, textures have to be power of 2

Thank you :-)

 

Ok for 2^x size of canvas.

 

So, it's not possible to draw a text with a transparent background and an emissive texture, tell me if I'm wrong.

 

How to write a pure red text (strong red like in emissive) with a diffuse Texture ? (if a want a transparent background)

Just add a white emissive color:
