    I am using universal render pipeline but I can't get the alpha to work inside render texture

    I tried setting camera color to solid with alpha, also render texture color format has an alpha in it but the alpha channel is always white

    Hi,

    Can you share some more information, for example the texture format and how the cameras are setup?

    This is currently working but there's some cases where the alpha will not be preserved, one case is with PostProcessing this has a high cane of clearing the alpha channel due to certain effects not working well with it.

    Hi,

    Is this the reason the new Blitter class will not write to the rendertexture transparency in URP ?
    I use the defaultHDR rendertexture format.

    Thanks
