I do as Janos suggested, worked quite well and pretty fast. We had quite
heavy props from speed tree and it wasn't that bad
def getMeshUVBounds(mapName, mesh):
mesh = pCore.PyNode(mesh)
uList, vList = mesh.getUVs(mapName)
if not uList:
uList = [0]
if not vList:
vList = [0]
return [[min(uList), min(vList)], [max(uList), max(vList)]]
def getMeshUVBoundsAsUDIM(mapName, mesh):
udimMap = range(1001, 1011)
bounds = getMeshUVBounds(mapName, mesh)
minU, maxV = int(math.trunc(bounds[0][0])), int(round(bounds[1][1] + 0.5))
return udimMap[minU] + (10 * (maxV - 1))
def isUDIMOverlappingBoundaries(mapName, mesh):
bounds = getMeshUVBounds(mapName, mesh)
if int(bounds[0][0]) == int(bounds[1][0]) and int(bounds[0][1]) ==
int(bounds[1][1]):
return False
else:
return True
