@SpiritWolf448  Watched the video link that you posted and you could use the Expandable Color Ramp to do most of what is shown in the video.  To set it up so that it only goes between the two points as the Blender color ramp starts off as.  (Start) Pos 1 needs to be 0, Color 1 can be whatever color you want (Black as the default Blender).  (Start) Pos 2 set to 1 and Color 2 to your choice (White for Default Blender).  Blend Type 1 as .1 or use the helper node as explained in the PDF manual.  This starts the ramp to go between those 2 colors in a linear fashion.  IF you set a lower (Start) Pos to be greater then the ones above it then it overrides the higher ones.  So for Color 1 if you set the (Start) Pos 1 to say .4 then from 0 to .4 it will stay as Color 1.  Only when it gets to .4 will it start to blend with Color 2 (and the blend type depends on the Blend Type mode set for that pair of colors).  Now if you set (Start) Pos 2 to say .6 and leave the Blend Type mode set at 0 then after the ramp hits a value greater than .6 it will stay at the value of Color 2.

Doing the above will result in an output similar to what you will get from the Blender Color Ramp.  Since Blender and Poser have very different UI layouts for the material room nodes this is about as close as you can get to the Blender Color Ramp.  It should be easy to translate the Blender Values to Poser IF you can find out what the color is and the Start Position for each point on the ramp.  And since Blender only allows a single Blend Type for all the color positions you just have to set the Blend Types to that mode.  That is an advantage of the Expandable Color Ramp is that each pair of colors can blend differently.  So you can go from Constant to Linear, back to Constant and then into a HSV color blend if you wanted to.

The Expandable 2 Color Ramp contains nearly 600 nodes to do what it does.  And 4 Color version around 1100.
