Large pixel tree shows a horizontal seam in the middle

[Val Bennett]

We have a 32 string x 100 rgb pixels per string megatree model in our display. In the simulation, some effects appear to create a horizontal seam in the middle of the tree (spirals for instance - see attached pptx file). The tree is 360 degrees around. Other effects don't appear to create the seam  (plasma, butterfly for example). The 12- ribbon CCR tree does not do this with the same effect programmed. Does anyone know what we are doing wrong, or is it an issue with the program?

All effects are rendered as if the model was a flat surface so when you wrap that flat surface into a circle there will be a seam.  The seam should be centered in the back of the tree.

[Val Bennett]

Gilrock - that makes sense, but shouldn't the seam be a vertical one in the back?

[Gilrock]

Yeah I didn't notice you had an attachment.  That is not the type of seam I was thinking of.  I'd do a Tools -> Package Sequence and post a zip file with that so we can figure it out.

Gilrock, here is the sequence package as you suggested.

Thanks for your help, let me know if I need to post any other info.

Ok that's happening because you have a perfect 90 degree rotation parameter so the white and red pixels hit the exact same spots and blend.  If you drop a new Tree model you will notice we default that parameter to 3 to give the front strands a slight offset from the rear strands.  So make the Rotation 93 and it will look normal.

Thanks Gil, I believe that did the trick!
