It would be great if Twinmotion were able to export a "Clown Pass" layer for post production selection / editing. Many of the competition does this and it would be incredibly beneficial. 
Hello ,
Thank you for posting in the community regarding your request for a clown pass. We have in our back log adding export functionally with layers and recommend you make a suggestion and/or comment on an existing tile where applicable. https://portal.productboard.com/7pu88c9kpmqtzt8hwg6arujh/tabs/4-under-consideration
This model looks really cool and like the touch of the dirt on the tires.
Kind regards,

Hello fellow KeyShot user. I feel your pain. Keyshot does rendering passes very well and TM could certainly take notes. I have been trying to raise awareness of the significance of TM's lack of post-production rendering passes in this thread: https://twinmotionhelp.epicgames.com/s/question/0D54z0000879YElCAM/render-elements-for-postproduction-must-come?language=en_US
Please weigh in over there if you have time. Somewhat inexplicably, this doesn't seem to be a priority for Epic.
Vincent,
Thanks for taking notice of this topic. There is an active discussion of render passes and why they are essential on this thread: https://twinmotionhelp.epicgames.com/s/question/0D54z0000879YElCAM/render-elements-for-postproduction-must-come?language=en_US
Please take a look at the discussion happening over there. I think post-production render passes are much more important to the industry than Epic seems to realize. This should be a top priority. It is a standard feature of every other notable rendering software and is essential to a professional workflow. Its absence is preventing industry adoption.
TM has such potential and this is the most notable thing holding it back. Anything you can do to escalate the issue would be appreciated by the community.
Thanks
