I ve been experimenting with Speckle as a results viewer and running into some color consistency issues when working with colored meshes.
Objective: Consistent mesh coloring between Rhino/GH and Speckle Viewer
Issue: There is something about the way the translator brings over mesh colors from Rhino GHopper to speckle shaders that makes the colors really washed out. If i had to guess it looks like its blending the render material ( which should be the default grey) with the mesh color or an error translating RGB values. I think whenever mesh colors are present the render material should be ignored, thats how it functions in rhino anyway.
Example: Provided screenshot with a colored mesh sent "as is " from grasshopper (without providing additional speckle render material inputs) vs the same colored mesh with speckle Render materials generated from mesh colors in GH instead of relying on the translator. The latter approach results in consistent colors between Speckle Viewer and Grasshopper / Rhino Geometry while the first one has brightness and contrast problems
