I know how to use “Only Shadow” in an object’s material so it can receive shadows but not render anything else, but is there a way to have it render “Only Reflection” where it would render the reflection of objects (not global textures)?
Meaning:
I want the end result to look like 3d Text sitting on top of a mirror, but be able to save it with an alpha channel so I can use it on different backgrounds.
Another use would be compositing and letting things like windows, TV screens, mirrors, etc that exist in the real world, and allowing them to reflect things from 3d renderings.
Sorry to get back for life such and old thread but I need to make a plane receive the “Only Shadows” that´s ok nothing difficult and its working but I need that this plane receive a reflection too, so I can render RGBA in PNG and apply all in Inkscape…
I dont understand the steps to do that in Fligh post…
That was so long ago I don’t understand it either. Since then we Blender has Texture Baking and Nodes added, both of which will probably do a better job.
Shadows don’t have reflections so you’re probably trying to do something else, but I’ll explain it anyway. An environment map consists of six shots of the surroundings taken from the position of the Object, then mapped to the relevant coordinates of that same object. When applied it is those images that are seen as the “reflections” on (say a chrome sphere) surface. You can save the environment map, open it in an image editor and manipulate it, and/or map it as an Orco or Refl Texture mapped to Refl.
For example, if I make a plane only shadow, and still apply a ray mirror of 1.0 and for last turn on AOC that will give me on the shadows the reflection, is it good but I think that someone knows how to achieve a better result.
