Grid calculation using Vertical Mapper 3.7

[wkaibigan]

Hi there.

 

I have a grid where I want to add some conditional values to the value currently in the grid.

 

If value is <0.25 I want to add 0.5 to the current value and anything above 0.25 I want to add 1 to the current value.

 

I can't see any way of doing conditional calculations that would allow me to do this.

 

Does anyone have any suggestions?

 

Thanks.

There is no easy way of doing this.  I would suggest creating two separate grids, one containing values <0.25 and the other containing >.25.  Next do some Grid Math, add .5 to the first grid created and 1 to the second grid.  Final step would be to Merge the two grids back to the original grid so that you are over writting the original values.
