Blender Version
Broken: version: 2.90.0 Alpha, branch: master, commit date: 2020-06-18 19:05, hash: rBb89898cbd381
Worked: (newest version of Blender that worked as expected)

Short description of error
I have created a simulation of an aeroplane crashing into the ground. However whenever I render out the frames with the smoke/fire simulation, what appears in the render is not the same as the viewport.

It either renders black and then changes colours.


Or the simulation is stretched and in different places

However, the viewport render looks fine.

The issue also happens in 2.83

Some more information about the scene

The scene contains a rigid body simulation, similar to the one of this tutorial. The airplane has a particle simulation along with an explode modifier. I also have 2 smoke simulations running. 1 of the airplane parts, and another of the ground debris. The particle simulation meshes and smoke simulation meshes are all children of the rigid body simulation (which is baked).

Thanks for the report, but unfortunately this can't be triaged as a complete bug report.

For the development team to be able to help, there needs to be reproducible steps (start blender, press this, then that ...) or at least a known regression (Blender version X worked, but not version Y).
If there are many steps to reproduce the problem, please attach a .blend file saved right before the bug occurs, so only a few steps are needed to trigger the bug.

Many bugs are fixed between the official releases. Please try the latest development snapshot of blender: https://builder.blender.org/download

No activity for more than a week. As per the tracker policy we assume the issue is gone and can be closed.

Thanks again for the report. If the problem persists please open a new report with the required information.
