Broken: bda017598402 (blender2.8 HEAD)
Short description of error
If you keyframe any material nodetree node input the playback performance suffers severely
Exact steps for others to reproduce the error
- Open wasp_bot.blend from EEVEE sample files.
- Replace the material of the HEAD object with a simple emission node.
Test playback performance in your system. - It should be fast.
- Keyframe the emission node color
Re-evaluate playback performance - It should be slow.
Note, performance goes back to normal in the following cases:
- If you animation data from the node (in dopeshet delete all the channels, instead of the individual keyframes).
- In mesh edit mode, add a cube and remove the rest of the head.
