63ac7c799c, type: ReleaseShort description of error
Particle don't update rotation settings in real time. One has to e.g. switch seed back and forth in order for the rotation settings to update.
Exact steps for others to reproduce the error
Create a particle system and try to change the rotation settings of the object particle.
and if you then disable rotation...
...blender ignores you for good.
Added subscriber: @user1
...but if you switch to halo rendering and back to object rendering, then the rotation is gone as expected.
wow, i just found out that it's even more weird: With rotation turned off, after the halo-trick, try to change the seed. You will see that blender still assumes that you want rotation.
Added subscribers: @Sergey, @mont29
Thing is, rotation belongs to particleSettings data-block, while seed belongs to Object data-block (through ParticleSystem data). Those do different things in
particle_recalc()update callback, and depsgraph also uses different components (seedepsgraph_tag_to_component_opcode()indepsgraph_tag.cc).@Sergey things are a bit confusing here, maybe you can understand what is missing here?
