Olson Landclass limit

[rsubers2]

I am using Prepar3dV6. Has anyone figured out a way to beat the 148 maximum olsonlandclass limit? The documentation says that this is a hard limit but Orbx appears to have figured out how to go beyond it since they have higher entries in it. If i add mine and create the appropriate .bmp files in scenery\world\texture and try to use it it just gets ignored. I want to put a custom texture over a large area using resample rather than have to use a very large polygon but resample used the olsonlandclass values.
