Is possible to set the Render Color from a Material in Revit? I’ve managed to mark the checkbox that says UseRenderAppearanceForShading while creating a New Material, but then the RGB is the Generic one (80,80,80). I’ll like to know if is possible to modify the Render Color has you can modify the other rest: SurfacePatternColor, CutPatternColor, Color. I paste the code i’m working in, just missing setting the Render Color. On the other hand, also would be nice to fill, all the rest of parameters, Manufactures, Description… if you know the ways that would be really useful. import clr clr.AddReference("RevitAPI") from Autodesk.Revit.DB import * clr.AddReference("RevitServices") import RevitServices from RevitServices.Persistence import DocumentManager from RevitServices.Transactions import TransactionManager clr.AddReference("RevitNodes") import Revit clr.ImportExtensions(Revit.Elements) def ToRevitColor(dynamoColor): return Color(dynamoColor.Red, dynamoColor.Green, dynamoColor.Blue) def ToDynamoObject(revitObject, isRevitOwned=False): # isRevitOwned should be False if Dynamo script created the object. return revitObject.ToDSType(isRevitOwned) doc = DocumentManager.Instance.CurrentDBDocument mat_name = IN[0] transparencies = IN[1] colors = IN[2] colors_surface = IN[3] colors_cutpattern = IN[4] use_render_app = IN[5] newMaterials = [] for mat_name, transparency, color, color_surface,color_cutpattern, uses_render_app in zip(mat_name, transparencies, colors, colors_surface,colors_cutpattern,use_render_app): TransactionManager.Instance.EnsureInTransaction(doc) new_mat_id = Material.Create(doc, mat_name) new_mat = doc.GetElement(new_mat_id) new_mat.Transparency = transparency new_mat.SurfacePatternColor = ToRevitColor(color_surface) new_mat.CutPatternColor= ToRevitColor(color_cutpattern) new_mat.Color = ToRevitColor(color) new_mat.UseRenderAppearanceForShading = uses_render_app TransactionManager.Instance.TransactionTaskDone() newMaterials.append(ToDynamoObject(new_mat)) OUT = "Oh Yeah Baby!!!" Thanks in advance for any idea. :v:

The color from Use Render Appearance For Shading is only grey until you give the material a render appearance asset with color information that doesn’t average out to gray.

Hi @Greg_McDowell, In Revit you can edit manually that color render appearance without selection any render appearance asset. I though maybe you could do the same as the other colors from Dynamo. Just in case i misunderstood your words. You mean that i should first assign an Render appearance asset and then i could change that color, all in Dynamo. About the other parameters affecting the Material, manufactures, description… any idea how i could reach them? Thanks for your time.

@Raul.Galdran did you manage to change any of the Appearance Assets’ properties? I am afraid that currently the API does not support this. You can create or duplicate a new appearance asset and assign it (or an existing one) to a material, but I could not modify its properties: gen=AppearanceAssetElement.GetAppearanceAssetElementByName(doc,"Generic") app=AppearanceAssetElement.Duplicate(gen,mat_name) new_mat.AppearanceAssetId=app.Id Even in the RevitAPIdocs there is no trace of something interesting: the AppearanceAssetElement class has a GetRenderingAsset and a SetRenderingAsset method which require an Asset as input. None of these however show some pretty properties like Color…

@GregX I didnt manage to make any change about the rendering material or textures. Thanks for the advise about duplicating the appearance from the material, i didnt know about this walkaroud. Thanks again for your time.

For anyone interested: [image] Set Material Parameters from Python Script Developers Trying to break through some mysteries here, I discovered some interesting things. I am on R2017 at the moment: First, the color of a material (the one from the Graphics tab) can be set with a simple Element.SetParameterByName node. The awaited value is an integer but I don’t know how this number is defined. I have been able to set a value from 0 up to 16777215. Second, the whole Appearance tab can be set by switching the material asset element with Material.SetMaterialAssetByAssetId or Materi…

Hello GregX, how did you get to make the Duplicate method work? I copied your 3 rows of code, and Dynamo says: AttributeError: ‘type’ object has no attribute 'Duplicate’ Do I need to import some functions from the API? Can you share the whole code? Thanks in advance!

Hello Yna_Db, my code goes like this: import clr clr.AddReference('ProtoGeometry') from Autodesk.DesignScript.Geometry import * #The inputs to this node will be stored as a list in the IN variables. matInput = IN[0] matToCopy = IN[1] import clr clr.AddReference("RevitAPI") clr.AddReference("System.Core") import System clr.ImportExtensions(System.Linq) from Autodesk.Revit.DB import * clr.AddReference("RevitServices") import RevitServices from RevitServices.Persistence import DocumentManager from RevitServices.Transactions import TransactionManager doc = DocumentManager.Instance.CurrentDBDocument assetArray = [] for i in range(len(matInput)): gen=AppearanceAssetElement.GetAppearanceAssetElementByName(doc,"Aluminum") app = AppearanceAssetElement.Duplicate(gen, matToCopy) matInput[i].AppearanceAssetId=app.Id assetArray.append(app) OUT = assetArray

It’s too late for me and someone else will surely help, but you could be interested to first take a look at one of the links mentioned in this post:
