I’m attempting to unroll a surface with a gradient texture on it. The gradient is smooth and seamless when I unroll one part of the surface, but when I unroll another part, it’s as though the texture has been reprojected onto the unrolled surface. The successful one (see screenshot) was unrolled with “Keep Properties,” the other one not so–so although I have done the exact same procedure for both, I got different results! This is pretty confusing.
The texture mapping was applied to the object on the left of the screenshot as a closed solid. It was a planar mapping of a rhino gradient material. Then I unjoined edges around the desired box template, and unrolled each side (displayed on the right side of the screenshot) separately.
I figured out that I can use the bake command to force the texture to be surface mapped rather than projected. However I wind up with a different version of the same problem. Now the first piece still unrolls correctly, but the second piece unrolls with the texture remapped to each individual surface. See image.
Am I using the bake command wrong somehow? It’s not like there are a lot of settings.
when i first tried it, i got a similar error which was caused by not creating a seperate material for the second object. Below attachement was done like this:
created the geometry from a solid cross
exploded the cross polysurface
while geometry was selected, i ran _RemoveFlippedNormals
joined surfaces to get upper part (A) and lower part (B)
used _UnjoinEdge four times on each part
created 2 new materials, one for each part using the gradient
set up the planar mapping from the top view, for each part seperately
used _Bake and saved two texturemaps (…A and …B), one for each part
used _UnrollSrf for each part with these settings:
this time it seemed to work. I guess the problem either happens because only a single material is used or because of the mapping not done individually. I am not sure if it makes a difference without removing flipped normals. Note that when you load the file below, you might have to re-assign the texture maps A and B.
