Quote - I made some tests at 33%, and the coconut trees looked alright...

I guess it's just my scene? Doesn't matter anymore though.

Quote - Strange it creates those artifacts, though. I tried it and I don't have the problem with 33% TF, did you add more than 33%?

The last time I rendered and it looked "blocky" like that it was around 8% TF.

Strangely enough, I used to not get this problem even if it was around 30-40%.

Oh well, it works now I guess.

Quote - It lookks like there is some texture filtering applied, and this migh be the reason why leaves seem to have lost some transparency, creating this "blocky" look. Check the render options, and in front of Object antialiasing, click on Edit, and in the new window, check on the right side if there is texture filtering applied. If so, setit back to zero. and rerender.
If you used a preset, any present above "final" (but not final) now uses tetxure filtering.

That was it! I had played with the texture filtering but never set it all the way down to zero.

Thank you! I'm going to take down those pictures now though, it's not finished, haha
