I am working on visualizing an astrophysical simulation that uses tracer particles to calculate temperature, density, and chemical composition in a supernova explosion. I thought I would use a Particle System, placing each particle at the location of each of the simulation tracer particles.
I have demonstrated to myself that I can modify each particle with a custom lifetime that I can access with a Point Density Texture and control color with a ColorRamp. However, I am running into trouble when I try to move the particles. I am using: bpy.data.objects['Object'].particle_systems[0].particles[i].location = (x,y,z) This appears to write the values into the Particle System data (I can see the modified values in a print statement) and when I cycle into Edit Mode, the particles are positioned in the 3D View. However, the behavior is not consistent and sometimes cycling through Edit Mode resets the particles to their original initial, pseudo-random locations. Am I trying to do something that isn't currently supported? (The API documentation does not have a 'read-only' flag next to the location attribute description.) If I can move particles to custom locations, what is the correct method? I'm relatively new to the Blender Python API, so I can't tell if I'm making a rookie mistake or there is something deeper I've missed. Thank you for any advice you can provide, Kevin
