map color_data channel - cgdvs - 05-06-2019
HI！Tyson
"Custom Properties" - save object map color channel
"Object Bind" - Bind Position_Limits_Limit offset can read the object map color, and can determine the offset height according to the color change. Can be set to animation.
"Speed" can increase the way the object normal is read. The speed value can be controlled according to the color of the object map.
"Surface Force"-Normals_ can control the intensity through the object map color

Hi cgdvs,
Particles don't have a mapping color, just mapping coordinates, which can later be read by the viewport/render to assign a material. You can sample colors from a texmap using a script operator, but not currently any other way.
All the other requests can easily be achieved using a script operator.
Attached is an example scene showing how to sample the nearest normal/color on a surface and use those values to set particle positions and outward velocity.
Once you get more familiar with scripting, you can enable multithreaded scripting capabilities which will greatly increase the speed of doing operations like this with a Script operator.

Thank you, you always think for our users. Thank you for your attention, I will definitely study the script node.
Encountered a problem, if there are multiple objects, what do I need to do?
