Hi Julien, The system as it is now, uses materials from the Object or Mesh itself. This has its specific benefits and limits, but for me its not clear what replacing it with a direct linkage to a particle system would improve.
The only use case I can think of is when a user decides to link a particle system to other objects in a scene, and allow this way q shared material for particles. Such a feature you could also code without changing the existing spec. Just add a material linkage option in the particle system, and make sure that choice (if set) overrides the index setting. That way no versioning is needed, and old files would read/write in a way that still works in current and previous releases. -Ton- ------------------------------------------------------------------------ Ton Roosendaal Blender Foundation [email protected] www.blender.org Blender Institute Entrepotdok 57A 1018AD Amsterdam The Netherlands On 30 Mar, 2013, at 13:46, Julien Duroure wrote: > Hi all, > > I implemented some code to replace, in particle render section, the > material index ( 1, 2 or 3 for example ), by a direct material choice ( > Material, Material.001, etc...) > > Code is now OK, but I am currenly working on do_versions, to be able to > open old files with this new "feature". > > I try to implement this kind of code : http://pastebin.com/Czy3rfqZ > But I have a segfault when access on part->omat. > It seems to be linked to preview.blend objects. > GDB said that psys->part adresse can't be access. > > I don't know how preview exactly works : is there someome can explain me > why I have this problem and how to correct it ? > > Thanks & Regards, > > Julien > _______________________________________________ > Bf-committers mailing list > [email protected] > http://lists.blender.org/mailman/listinfo/bf-committers _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers
