particle question 2005-03-04 - By Aloys Baillet

Just to be more clear:
run this JScript:
NewScene(null, null);
CreateParticleCloud("", "Grid");
SelectObj("PEmitter", null, true);
Scale(null, 10, 10, 10, siRelative, siLocal, siObj, siXYZ, null, null,
null, null, null, null, null, 0);
Create2DMap(null, "Texture_Map", siDefaultPropagation);
CreateProjection("PEmitter", siTxtPlanarXZ, siTxtDefaultSpherical,
"Texture_Support", "Texture_Projection", null, null, "");
SetInstanceDataValue(null, "PEmitter.Texture_Map.UVReference",
"Texture_Projection");
SetValue("cloud.cloud.ParticlesOp.PEmitter_emission.MapColor", true, null);
ApplyOp("MapCompOp",
"PEmitter.Texture_Map;PEmitter.PEmitter_emission.MapColor", null,
null, null, 0);
SetValue("cloud.cloud.ParticlesOp.PEmitter_emission.Rate", 500, null);
SetValue("cloud.cloud.PType.LiveForever", true, null);
SetValue("cloud.cloud.ParticlesOp.PEmitter_emission.Speed", 0, null);
PlayForwardsFromStart();
Then run this one:
SelectObj("cloud", null, null);
SetParticleInitState("cloud", 0);
FirstFrame();
SetValue("cloud.cloud.ParticlesOp.PEmitter_emission.Rate", 0, null);
CreateForce("Turbulence", "");
PlayForwardsFromStart();
