* Added per surface options "influence scale" and "radius scale" for tweaking brush settings individually for each surface.
* Added option to completely disable drying. This should be nice for indefinitely spreading paint etc.
* Improved paint mixing algorithm.
* "Paint effects" now work in relative mesh space instead of global. This means that effect speed remains same for identical shapes regardless of their size.
* Complete rewrite of "spread effect" algorithm. It now works much better in all test cases done. Old algo sometimes produced artifacts and stopped spreading too early.
* Adjustments / rewrite on some parts of dripping algorithm to make it work better with transparent paint.
* Added a new "color dry" setting. It can be used to define wetness level when paint colors start to shift to surface "background". Lower values can be useful to prevent spreading paint from becoming transparent as it dries, while higher (default) values give better results in general.
* Fix: If multiple displace/wave surfaces were used simultaneously, displace was applied using wrong normal.
Please note that due to these changes in "paint effects" system older save files may require some tweaking to match results from previous versions.
This commit extends limit of ID and objects to 64 (it means 63 meaning
characters and 1 for zero-terminator). CustomData layers names are also
extended.
Changed DNA structures and all places where length constants were hardcoded.
All names which are "generating" from ID block should be limited by MAX_ID_NAME-2,
all non-id names now has got own define called MAX_NAME which should be used all
over for non-id names to make further name migration stuff easier.
All name fields in DNA now have comment with constant which corresponds to
hardcoded numeric value which should make it easier to further update this
limits or even switch to non-hardcoded values in DNA.
Special thanks to Campbell who helped figuring out some issues and helped a lot
in finding all cases where hardcoded valued were still used in code.
Both of forwards and backwards compatibility is stored with blender versions newer
than January 5, 2011. Older versions had issue with placing null-terminator to
DNA strings on file load which will lead to some unpredictable behavior or even
crashes.
* Fix: Smudge and brush velocity settings didn't work for "image sequence" surfaces unless any paint effect was enabled.
* Adjusted some property ranges.
- curve map insert point had a nested loop which used the same value to index different arrays.
- dynamic paint used ternary operator where both outcomes were the same.
by Gaia Clary.
Rationale: the name was confusing and not always used consistently, and this
map itself is not something that can be layered, rather the map can be used
as texture coordinates in some layered setup.
The original intent was to indicate this contained more than just UV's, but
the game engine settings have already been moved out, and apparently users
didn't really get this from the name anyway.
* Vertex color output now works even if there is a constructive modifier, like ocean sim, before dpaint.
* Fixed a crash when canvas mesh had no vertices.
* Fix: Smudge was also processed for incompatible surface types causing corrupted output.
* Wave simulation speed doesn't anymore depend on surface size, but uses relative distances instead. This change will likely change simulation behavior on existing saves, but can be easily tweaked back using the "Wave Speed" parameter.
* Added a new wave brush type, "Depth Change". It uses the change of brush intersection between frames, giving a better looking "wake" for moving objects. It also doesn't leave any "dent" to the surface while remaining still.
- use NULL rather then 0 for pointers
- use static functions where possible
- add own includes to ensure func's and their declarations don't get out of sync.
if a value other than 1/0 was given it would use an uninitialized pointer too (compiler warning, review should pick up this stuff).
also renamed some RNA attrs:
output_name --> output_name_a
output_name2 --> output_name_b
do_output1 --> use_output_a
do_output2 --> use_output_b
do_smudge --> use_smudge
max_velocity --> velocity_max
* Renamed "Sharp" proximity falloff to "Constant".
* Added a new "Negate Volume" option for "Volume + Proximity" brush.
* Possible fix for random particle clipping errors.
