I now know why I cannot see the anal morphs in timline (maybe just my installation?). The morphs favourite button does not save. I click it and I can see the tick temporarily, but it has not actually saved it. Works fine with all other morphs. No worries, I found a work around, messy but it works. I used SPQR's Morphblend, works perfect. Directly wrote in the ID for the morph and I can make the anus go in and out using timeline. This can give a better visual appearance in animations (anal grip etc), maybe for futa usage too. Even in photos it can look better than the standard view. Sorry if the photo is not your thing. Just sharing for those who are interested.
