Hello
I’m working on a project which I need to get a reflection image of the object.
I get the GlossInd pass,and use Mix node to make background transparent.
But after I saved the image,the image blender output is 100% blank and have no reflection.
I am confused why blender shows and output are different?
Can anyone help?
Try using a transparent background…in the Film setting
In compositor use the GlossDir instead…
Or you could just render multiples and composite later…
Not really sure what you want for the end product…
Now if you want ONLY the reflections…
Use the Image saved from above and use it to render ONLY the reflections on the cube…over transparency…
and as @Calandro said all of this would be simplified if using Multi-Layer EXR
Are you saving your image as OpenEXR muiltilayer? If that’s the case you must remember that you don’t have an alpha channel, you have an alpha layer and it will not be seen as alpha until you use a program that interprets your layer as an alpha layer.
You can see transparency if you save your image as PNG RGBA or OpenEXR RGBA. Where the alpha comes as a channel and not a layer.
