Cycles Bake Expand Cycles to use the new baking API in Blender. It works on the selected object, and the panel can be accessed in the Render panel (similar to where it is for the Blender Internal). It bakes for the active texture of each material of the object. The active texture is currently defined as the active Image Texture node present in the material nodetree. If you don't want the baking to override an existent material, make sure the active Image Texture node is not connected to the nodetree. The active texture is also the texture shown in the viewport in the rendered mode. Remember to save your images after the baking is complete. Note: Bake currently only works in the CPU Note: This is not supported by Cycles standalone because a lot of the work is done in Blender as part of the operator only, not the engine (Cycles).

void create_session();
void free_session();
Cycles: persistent images option This option enables keeping loaded images in the memory in-between of rendering. Implemented by keeping render engine alive for until Render structure is being freed. Cycles will free all data when render finishes, optionally keeping image manager untouched. All shaders, meshes, objects will be re-allocated next time rendering happens. Cycles cession and scene will be re-created from scratch if render/ scene parameters were changed. This will also allow to keep compiled OSL shaders in memory without need to re-compile them again. P.S. Performance panel could be cleaned up a bit, not so much happy with it's vertical alignment currently but not sure how to make it look better. P.P.S. Currently the only way to free images from the device is to disable Persistent Images option and start rendering.

Border rendering now works for all scenes used in compositor, before this only active scene would be rendered with border. When do_render_fields_blur_3d() is finished, it'll modify render's display rect so it'll correspond bordered render result placed on black backgrund. Actual border is stored nowhere, which makes it only way to re-calculate disprect for all other renders used in compo based on source. Not so big deal actually. Also needed to modify Cycles a bit, because before this patch it used border settings from scene being rendered. Now made it so render data is passing to external engines. Using a property inside RenderEngine structure for this. Not best ever design for passing render data, but this would prevent API breakage. So now external engines could access engine.render to access active rendering settings. Reviewed by Brecht, thanks!

Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report. Everything else is likely small todos, and may wait until we are sure none of the above is happening. Apart from that there are those known issues: * Compositor Image Node poorly working for Multi-View OpenEXR (this was working prefectly before the 'Use Multi-View' functionality) * Selecting camera from Multi-View when looking from camera is problematic * Animation Playback (ctrl+F11) doesn't support stereo formats * Wrong filepath when trying to play back animated scene * Viewport Rendering doesn't support Multi-View * Overscan Rendering * Fullscreen display modes need to warn the user * Object copy should be aware of views suffix Acknowledgments =============== * Francesco Siddi for the help with the original feature specs and design * Brecht Van Lommel for the original review of the code and design early on * Blender Foundation for the Development Fund to support the project wrap up Final patch reviewers: * Antony Riakiotakis (psy-fi) * Campbell Barton (ideasman42) * Julian Eisel (Severin) * Sergey Sharybin (nazgul) * Thomas Dinged (dingto) Code contributors of the original branch in github: * Alexey Akishin * Gabriel Caraballo

Cycles: Report error to the blender using report API This way when something goes wrong in Cycles (for example out of VRAM, timelimit launching the kernel etc) we'll have a nice report in the Info space header. Sure it'll be nice to have mention of error in the image editor's information line, but that's for the future. This fixes T42747: "CUDA error" appears only momentarily, then disappears

Fix #34714: cycles viewport render would restart when minimizing and unminimizing a maximized Blender window in Ubuntu Unity. The window size would slightly change as part of the unminimize effect. Now cycles waits 0.2 seconds before restarting rendering after a viewport resize, also a bit less flickery when changing the 3d view size in Blender itself.

Packed and generated images support for Cycles This commit adds support of packed and generated images for Cycles when using SVM backend. Movies are still not supported. This changes also doesn't touch OSL which is much less trivial to adopt for any images which are not saved to disk. Implementation details: - When adding images to Image Manager is now possible to mark image as builtin. Builtin images will bypass OIIO loader and will use special loading callbacks. - Callbacks are set by Blender Session and they're using C++ RNA interface to obtain needed data (pixels, dimensions, is_float flag). - Image Manager assumes file path is used as reference to a builtin images, but in fact currently image datablock name is used for reference. This makes it easy to find an image in BlendData database. - Added some extra properties to Image RNA: * channels, which denotes actual number of channels in ImBuf. This is needed to treat image's pixels correct (before it wasn't possible because API used internal number of channels for pixels which is in fact doesn't correlate with image depth) * is_float, which is truth if image is stored in float buffer of ImBuf. - Implemented string lookup for C++ RNA collections for cases there's no manual lookup function. OSL is not supported because it used own image loading and filtering routines and there's seems to be no API to feed pre-loaded pixels directly to the library. Think we'll either need to add some API to support such kind of feeding or consider OSL does not have support of packed images at all. Movies are not supported at this moment because of lack of RNA API to load specified frame. It's not difficult to solve, just need to consider what to best here: * Either write some general python interface for ImBuf and use it via C++ API, or * Write a PY API function which will return pixels for given frame, or * Use bad-level BKE_* call Anyway, small steps, further improvements later.

Cycles material preview: fix for generated/packed/movie files Issue was caused by cycles trying to find builtin images in a main database and in case of preview render images are not in database, they're just referenced by shader node tree. Now builtin images in cycles have got void* pointer to store data needed to load builtin images. In case ob blender session, this pointer will store pointer from PointerRNA for image datablock and used later to construct Image class based on this pointer. This also saves database lookup for final render which is nice :) Reviewed by Brecht.
