I have a scene with flying drones which are being hit by gunfire. The scene is heavy with multiple different objects. But tyFlow particles setup is simple - I just create sparks explosion when drone is hit by gunfire. The sparks explosion by tyFlow particles renders fast, ~6 seconds. But the more animated objects I have in the scene, the more render time, even if animated objects are not linked with tyFlow anyhow and hidden from render. In my simplified scene I have animated drones, with rigged animation. They are hidden from render and do not have effect on tyFlow anyhow. But with them presented in the scene render time increases to ~59 seconds. In my original scene with all objects, render time is even much worse, ~8 minutes. I tried to cache particles. It improves render time but not so much. When I have many animated objects in the scene I see 'Calculating TMs...' phase very long before render starts. Can someone give me a clue what should I do to reduce render time, please?
I have attached archive with two .max files:
bug_test_sparks_problem.max - this scene is just a sparks explosion (render frame 1406)
bug_test_sparks_problem_w_drones_simplified_2.max - this is scene with animated and hidden drones added to previous scene (render frame 1406)
I use 3ds Max 2024.2.7, V-Ray 7.20, tyFlow 1.130
