Default O-grid mesh on cylinder with 90 degree angle not pretty

Hello all,

I've been following a tutorial on how to create an O-grid mesh on a cylinder geometry (https://youtu.be/8_osCXZjv_g) and it worked well. However, when applying this same technique on a cylinder with a 90 degree bend I don't get something as nice as for the straight cylinder.

Here's what I get for the cylinder with the bend:


And here is what I get for the straight cylinder:


The dimensions of the circle at the base of each cylinder are different, but I have kept the ratios between the size of the square and the size of the circle similar.

Any ideas on why this happens and how to solve it?

Thanks!

Actually I managed to solve this by setting up an edge sizing on both the square in the middle and on the edges on the sides of the pipe. I had tried this before posting initially but I guess I hadn't set up the right parameters in the number of divisions.

By the way as I mentioned in the first I had originally kept the same ratio of the square to the circle diameter as in the tutorial, but it seems if I take one slightly different it doesn't work as well:



So once again I'm stuck. Tried playing with different edge sizing but with no luck this time

Did you check the lower two edge biasing directions?
