A strange superfly UV mapping issue
-
Would anyone care to guess at why this boat, which has always rendered fine in Firefly, has partially screwed maps when rendered with Superfly? It's not the first model I've seen this on. I realise the first one is not perfect, but the second is clearly much different.
-
@matb I'm guessing: The sea is low poly and using displacement map in firefly and the boat is low res with separate unwelded polys and is something to do with either crease angle or subD
-
Ahh sorry, yes the issue with the sea is definitely a matter of not using sub-d, but I'm actually more concerned with the mapping on the frame of the boat.
-
Also: If you are using the cycles image map instead of the Poser image map that might happen as the cycles map isnt UV'd the same way and hasd to be altered to work the same.
-
@matb I still think it is to do with smooth and the crease angle on the boat model
-
Another example. This time with a procedural texture.
Firefly
Superfly
The surface is UV unwrapped and uses a flat material, but look at the way the Superfly material does weird things at the edges and along the central horizontal axis where there is a boolean hole.
-
@ghostship Thank you. Nope IDENTICAL map, not a cycles version.

So how do you suggest I resolve it?
-
@amethystpendant OK, tried changing crease angle in 10 degree increments from 0 to 180 degrees and turning object smoothing off, but no change. Am I missing anything?
-
@matb No that was what I was guessing obviously not that, sorry
-
@amethystpendant Lol - well thanks for trying anyway!

Last time I saw this particular artifact, it was on my own mat-pawn which isn't UV mapped at all. The stretching was caused by subdivision.
-
Show a wireframe of the boat. I'm guessing we are going to see some serious NGONS in that wireframe. Poser especially dislikes long triangles.
-
@bagginsbill ahh, in fact it is subdivided. Unfortunately needed for some surface displacement - only visible here in the firefly version. Thanks for suggestion.
-
@Glitterati3D Ahh, yes, I'll check that Glitterati thanks. It IS an old product, so perhaps its creators were not aware of that limitation.
