I have one question about one problem in my experiment with motion blur in Eevee. I know that in this time is not supported and maybe will be supported in future official release as another primary function, but I want to try some experiment with Vector pass from Cycles.
I would like to try to make render of car with animation of fast rotating back wheels. I make two scenes (duplicate, not linked).
I join this two scenes with separate Layers setups and render engines together in compositor. The same node tree is in the both scenes.
It works pretty well (picture), but It has a problem. It works only if I start rendering manualy by render button on scenes nodes, but it don´t work if I push F12 or Ctrl+F12. It rendered all scenes only in one renderer in actual scene. It do not switch them.
Please help me find out a issue, where is a problem. Thanks a lot :).
Note: For this test I use model from Blender Corvette modelling tutorial from CG Masters
