no rounded logs for Dynamic Trees mod's trees...

could it be the problem at their side?

Hey there. I'm the author of dynamic trees. The "problem" is on my side. I do a custom model that I generate internally(no json) because the model would be unmanageable otherwise. So it's pretty much on me to implement this and I have no plans for ever supporting rounded tree trunks. The feature would be more complicated than I'm willing to put up with. Sorry.

It might be possible to do special support from my side if the blockstate is not too complicated, but it's likely to be a lot of work.
I'm not sure about this yet, I may just pass on it, but even if I do it it'll be only for the maximum-size trunks. I found that thinner columns don't look good when rounded anyway.

yeah agreed, i recommend only the main logs that on the middle.(biggest ones) (be rounded)
