viewport 2d without sampling + canvas give error, how should i fix it?
0.my main world is 2d, and i have WorldEnvironment with mode canvas in it
-i need a glow effect so i need canvas

1. when i spawn sprite with viewport as texture i get this error
   -render scene: can't use canvas background mode in a render target configured without sampling
2. in my viewport setting, i just put usage = 2d without sampling and transparentBG = true
3. if i use other, i will get black backgound
   how should i fix it?
