1:in daz,opacity add png ,but plane is transparent to show cube,  though  cube can be seen  through holes too, and plane color is light.

2:in blender ,plane is not trasparent ,which cube only can be seen through holes. and plane color isn't light.

Wrap up

  1:Rendering is in blender which I want..

  2:Why color is light in  opacity of surface in daz ?

  3:In daz, how to do same  of  rendering in  blender ?

Studio has never been able to handle Alpha channels directly, with DS3 it meant using the Layer Image Editor (LIE) or build a custom shader with the ShaderMixer.

With DS4 you have the ShaderMixer for 3Delight but not with Iray, none of the MDL bricks give access to the Alpha channel, you have LIE as well, and an "Image Editor" built into the Surface tab that can force an Alpha to be used.
