I have a very simple tyFlow setup, which creates smoke trail behind the missile, with animated texture for particles. The problem is that 3dsmax viewport is very slow when I have this tyFlow object visible, even if it is disabled. If I hide tyFlow object, then I can play animation in viewport in real time again. I cannot figure out such behavior and I expect that if tyFlow is disabled then it shouldn't cause any slowdown to the scene. I think this might be a bug. I have attached my .max file. I use 3ds Max2024.2.3, V-Ray 6.20.02, tyFlow PRO 1.106.
- In attached file try to play animation in camera viewport. It should be very slow, not real time preview.
- Now, turn off tyFlow_HGV_Smoke object and play preview again. Preview should play in real time. Please note that tyFlow object is disabled.
Update. This slowdown is linked to tyFlow object material. If I remove material from tyFlow object then viewport slowdown is gone. It looks like tyFlow updates material even if material is not active in Material Editor and tyFlow object is disabled.
