Assigning color with a material file

BenLoosli — Wed, 22 Feb 2023 17:36:33 GMT

Is it possible to define a color from appearance.dmt to a specific material in the .mtl file itself?

I want all parts made from SAE J995 Grade 5 to be a certain color. Is there an entry that can be put in the material file to change the color when the material is assigned?

Yes it is. See the article below:

When defining (or redefining) the material, go to the appearance tab, select new, pick a color, and set the color as default. Back in the Materials window select your material and save.

I linked to the wrong thing. Try this instead:

In short you need this in your mtl file:

{
Name = PTC_DEFAULT_APPEARANCE
Type = String
Default = 'glass'
Access = Full
},

and you need a corresponding appearance in your global.dmt file

Hi,

it seems to me that the appearance mentioned in material definition file must be included in global.dmt file.
