I tried other parameters and found that only "blur" and "filtermode" parameters had an effect.

I tried to edit colormap's filter parameter in maps baker HDA. But no matter I set "filter" or "width" parameter, the result was still looked the same as rawcolormap() function. The texture I read is a diffuse texture in PNG format and my Houdini version is 19.5 .The colormap function I used was like What should I do to get the filtered result by colormap or other function?

I want to set some parameter or press some buttons when enter a node and I want to use script to achieve it instead of do it myself. How can I get the event?
