Composite "Map UV" node was using false UVs (0,0) from neighbouring
pixels when those pixels were not rendered (or have no UV).
This commit checks for each neighbour sample it takes if the UV was
correctly set. Solves bad errors on edges of UV maps. With FSA even
totally smooth. :)
Third transparent shadow bug... this time it's a Material Node, which
has mirror + transp-shadow on, and when it traces its own material it
enters an eternal loop...
Raytracing + shading + materialnode combo really needs work!
Texture nodes hang when nodes have a cyclic case.
Added a (temp?) provision to tag node->need_exec zero for cyclic
nodes, and added check for this in texture nodes.
There was also a bug in 'tag changed' for texture nodes, which not
only tagged, but also called the tree exec (should not happen!).
In general the texture exec needs recode; it doesn't use the stacks
as provided per node, but recurses itself to previous nodes, giving
problems like this. Node execs should only do their own bizz, the
node system handles dependency and eval order nicely already.
- The armature weakref list was being incref'd twice then decrefed twice (incref and decref were used incorrectly), now only once. My 'fix' broke this.
- In bpy_pydriver_create_dict the 2 refs added from running PyDict_SetItemString twice were undone when clearing the dictionary (added comment)
- changed Py_XDECREF to Py_DECREF int BPY_pyconstraint_update and BPY_pyconstraint_target, Py_XDECREF checs for NULL value which would have crashed blender before it got to Py_XDECREF anyway.
- after every error is reported (PyErr_Print), remove sys.last_traceback and clear the error, I found this fixed certain crashes (usually when starting the game engine or exiting blender), so best do this all the time.
- header_text.c, CcdPhysicsEnvironment.cpp, KX_CameraActuator.cpp - remove some warnings.
* I accidently broke the scons bit by chopping the node libs into pieces. I forgot that trunk hasn't had the nice scons cleanout I did in Blender 2.5 branch. Now everything should compile again.
It took a while because I tried to quickly do the same cleanup, but src/ is just not cooperating, neither is stock mingw (no @commands.txt tempfilemunge goodies)
* BLI_linklist_index() - to get an items index in a LinkList
* BLI_memarena_use_malloc() - BLI_memarena_use_calloc alredy existed but there was no way to switch back to malloc.
also added texnodes to cmake
Robin (Frrr) Allen did a decent job on this, so we can also welcome him
as a member in the svn committers team to maintain it!
I do the first commit with some minor fixes:
- get Makefiles work
- fix rounding issue with tiles on unit faces
- removed UI includes from tex node
A nice doc in wiki is here:
http://wiki.blender.org/index.php/User:Frr/TexnodeManual
On the todo for Robin is:
- When using one or more Texture-input nodes, you cannot edit them by activating
(as works now for Material nodes).
- The new "output node" option fails on the default case, when only one
output node is active. It then shows often a blank menu. Will get fixed asap.
- When using a NodeTree-Texture as input node, the menu for 'active output'
should not show. NodeTree should ignore other nodetrees to keep things sane
for now.
- On a future todo is proper usage of "Dxt" and "Dyt" texture vectors for
superior antialising of checkers/bricks.
General note; I know people are dying to get a full integrated shader system
with nodes. In theory we could merge this with Material Nodetrees... but I
rather wait for a solid and very well thought out design proposal for this,
also including design ideas for unifying with a shader language (GPU, CPU).
For the time being this is a nice extension of current textures. :)
the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.
It turns out the material AmbCol property was never working properly, or even supported in the renderer, so I've removed it. Also included is a fix to make the 'Amb' input work properly too.
1) Added support for a var called "__node__" in pynode scripts, that can be used to point to the desired pynode object, to make sure it is chosen.
2) Fixed a semi-obscure crash that could happen when reparsing a pynode script that was used by multiple nodes in different scenes. Memory corruption would happen if the reparsing failed during the recreation of the pynode object, not when executing it.
