Hi. I have been using twinmotion on and off and it is fantastic but I am having the same issues. For whatever reason it appears that all the key frame changes does not work at all as I intend. For example, I saw this video below and I wanted to make a slow depth of field change and I thought I applied DoF on one single key frame. However, it turns out it is now applied to all other frames. I tried to add another key frame where I turn it off and it turns off for a half second and then continue again with the depth of field (blurry). Btw, another issue is that there does not appear to be a far DoV where the closest becomes blurry but that is secondary for now. This instant turn off is also true for disabling certain items. Say I want to disable a specific element on a view then I thought that if I turn off say a table on first keyframe and then remove it on the second then it will be removed all throughought key frame 1 and 2 but no, it flicks off for a second and turns on and then flicks of again for the second frame. I am sure there is something I do not properly understand though.
