Hello,
Is there any way to make the upres solver to respect collision from the initial simulation?

I am trying to retime smoke simulation and make it 5-6 time slower but keep exact shape.I tried doing that by linearly interpolating the cache between current and next frame but when you go more than 3 times slower it starts to be visible.Then i used upres re timing option which is working great but it has one major problem it doesn't respect the collision. Is there a way to include a collision to upres solver.Does anyone done that before?Any tips?
Thank you!
