Convert Display Color to Render Material?

Rendering
1

There are some really nice scripts that can randomize and interpolate display colors for shaded mode. Is it possible to convert display colors to Rhino 7 materials?

Thanks!

Yes, there is a command for it.

Select your objects and type:

SynchronizeRenderColors

It will create a material with the color of the later I believe.

Shynn Sup thank you! Completely forgot about that command.

SynchronizeRenderColors – this command does not convert an objects display color to a render material – converts an object to a layer color. Don’t see any further options for this command.

Set object color - Scripting - McNeel Forum

You probably need to use some python script, assuming one material per object. If you have too many object you will end up with a huge amount of materials in the file which may cause a problem.

I think you can use the script as a starting point,

To get the options you need to type _

_SyncrhonizeRenderColors

Here’s an older python script to convert Display color to Material color – not sure who made it, but it doesn’t seem to work in V7 – this is the exception message I get when running.

Here’s the script.

public DisplayMaterial CreateDisplayMaterial(
string filename,
double alpha,
Color color,
double shine,
double transparency
)
{
var material = new DisplayMaterial
{
Diffuse = color,
IsTwoSided = false,
Shine = shine,
Specular = Color.White,
Transparency = transparency
};

// Set the environment map
material.SetEnvironmentTexture(filename, true);

// Tweak the environment map
var texture = material.GetEnvironmentTexture(true);
if (null != texture)
{
texture.TextureCombineMode = TextureCombineMode.Blend;
double constant, a0, a1, a2, a3;
texture.GetAlphaBlendValues(out constant, out a0, out a1, out a2, out a3);
texture.SetAlphaBlendValues(alpha, a0, a1, a2, a3);
}

return material;
}

That is because the code is not Python but C#.

I am not sure I am following, that is exactly what the command does, no need for a script.

Ah! Thanks Nathan, obviously not familiar with python and c# code. The file I have has a .py extension, so wrongly assumed it was phython.

Shynn Sup, are you saying the command is _So_SynchronizeRenderColors?

Thanks

SynchronizeRenderColors should work fine.

_SynchronizeRenderColors for options.

Thanks Shynn Sup – the command does work, just not what I’m trying to do, unless I’m missing something. The _SynchronizeRenderColors uses the layer color (which can be different than object color) for rendering. I can use _SetObjectDisplayMode on the 150 objects to display shaded when I render which is a work around – it doesn’t work if I’m tyring to render with raytrace.

What I’d like to do is take all 150 objects which are all on the same layer and which I’ve run a progressive color script to create unique display colors, convert the display color to a render material, which uses the display color for the material color.

Thanks again,

I see, the command does work for Object display color, but each object needs to be in a separate layer.

I found the script you need here. (VB language)

Set Material Colors from Object Colors.rvb (1.5 KB)

To run the script:

Command: Loadscript/ Then select the file I just attached.
Command: Runscript

Perfect! Thank you, works beautifully.
