Yes Mohammad,
Martin has the solution right there
The theory behind it you can find in the course: Fundamentals of Compositing
And if you need check also the course: Moving from Blender 2.7 to 2.8
and especially chapter 4. Render Layers vs. View Layers
View Layer Outliner Toggles
how I upload my blender file I have some issue to render seen please tell me how i upload the file
in cycle...I don't know what's going on somebody can solve this please
Hi Mohammed, you can upload your .blend file to googledrive, Dropbox or so and then post a link here...
But one thing that's wrong, is that the model is in Edit Mode (see Warning),
Also, if you want to use Eevee to Render the Character, the Objects with the Holdout Shader need to have the Blend Mode set to anything but Opaque, in order to work.
I suggest you watch some of the training that's on CG Cookie, Adrian put of some of the links for you. Blender is a big beast and it is impossible to walk someone through the entire process by text on threads. You need to have the basics right and then practice a lot. We are here to help, yet we can't walk everyone through every click of the mouse though.
