System Information
Windows 8.1 Nvidia GeForce GTX 670MX

Blender Version
Broken: 2.76 RC Date 2015/09/21 00:32 Hash : 034cc85

Short description of error
Particle objects are not baked when normal map baking in cycles. This works as expected in Blender internal. Is this something that is deliberately left out of cycles normal map baking?
Blend file is included.

Exact steps for others to reproduce the error
set up a particle system on an object, set it to use an object or a group as the rendered particle.
create an image that can be baked to and selected in the material node editor.
Select the object with the particle system, the object/s that make up the group in the particle system and then make a plane to be the object to be baked to. (ensuring it is unwrapped and is the active object).
Set the bake settings to be of a 'normal' type and then select 'selected to active'.

In cycles the particle objects will be ignored, in blender internal they'll be taken into consideration.

NOTE : Some cycles passes such as ambient occlusion DO seem to be affected by the particle objects, but the particle objects themselves wont be rendered. BlenderCyclesParticleBake.blend

@dfelinto, is it similar thing to what you're addressing in D1271?

Most likely. @VilemDuha do you still have a build of "dupli object" fix at hand? could you try the sample file in this thread to see if it is fixed too?

Yup, it's the same issue as #43553. With a build from D1271 I get this result (so it's also fixed by that solution)

Is this something that is just waiting to be merged into trunk at some point? After a review from Brecht?

Anyway, great to know this is intended for cycles. Thanks Dalai!
