Yes, again.
There's some t within which reset is not allowed. This is so no reset happens
too often for performance issues. If camera changes too often, some reset could
be missed because of this timeout.
For now tag engine for update, which will update viewport from blender side.
Proper solution could be to detect such a changes from blender side and tag
cycles for refresh instead of trying to detect changes form cycles, but that's
for later.
* Enable Lamp MIS again, it works on a GTX 570 (which is sm_20) with latest SVN. Tested by vitos1k in IRC:.
Feedback from GTX 580 users would be appreciated on this.
which makes it impossible to toggle from fullscreen to windowed mode
when startup.blend is saved in fullscreen mode.
Reshuffled checks a bit, which is actually makes sense, will investigate
which change caused regression since 2.65a tomorrow.
Issue was caused by rare cases when camera move happens just after
last sample was finished, this would lead to missing delay reset
because render cycle will go to pause_cond.wait(). No reset will
happen at this point because of some kind of optimization which
checks whether camera is tagged for update and wouldn't do reset
in this case.
Talked to Brecht and seems this optimization is not actually needed
and removing it will solve issue with frozen preview.
Issue was caused by couple of circumstances:
- Normal Map node requires tesselated faces to compute tangent space
- All temporary meshes needed for Cycles export were adding to G.main
- Undo pushes would temporary set meshes tessfaces to NULL
- Moving node will cause undo push and tree re-evaluate fr preview
All this leads to threading conflict between preview render and undo
system.
Solved it in way that all temporary meshes are adding to that exact
Main which was passed to Cycles via BlendData. This required couple
of mechanic changes like adding extra parameter to *_add() functions
and adding some *_ex() functions to make it possible RNA adds objects
to Main passed to new() RNA function.
This was tricky to pass Main to RNA function and IMO that's not so
nice to pass main to function, so ended up with such decision:
- Object.to_mesh() will add temp mesh to G.main
- Added Main.meshes.new_from_object() which does the same as to_mesh,
but adds temporary mesh to specified Main.
So now all temporary meshes needed for preview render would be added
to preview_main which does not conflict with undo pushes.
Viewport render shall not be an issue because object sync happens from
main thread in this case.
It could be some issues with final render, but that's not so much
likely to happen, so shall be fine.
Thanks to Brecht for review!
When using triangle primitives this fix enables 'closed tip'.
UVs and vertex colours are added when using triangle primitives for hair.
Two new preset modes have also been included to allow easy access to curves and triangle planes.
