How to assing .mtl file color

[hjarvela]

Hi,

I have would like to assign a spesific photolux color (adv-steel) for my .mtl file but the color won't show up in the model.

Here is the file that I'm trying to use

ND_RelParSet_K01 = {

Name = BFACJ

PARAMETERS =
{
  Name = PTC_MATERIAL_DESCRIPTION
  Type = String
  Default = 'BFACJ'
  Access = Full
},
{
  Name = TEMPERATURE
  Type = Real
  Default = 0.000000e+00 C
  Access = Full
},
{
  Name = PTC_INITIAL_BEND_Y_FACTOR
  Type = Real
  Default = 5.000000e-01
  Access = Full
},
{
  Name = PTC_BEND_TABLE
  Type = String
  Default = ''
  Access = Full
},
{
  Name = PTC_MATERIAL_TYPE
  Type = Integer
  Default = 9
  Access = Locked
},
{
  Name = PTC_FAILURE_CRITERION_TYPE
  Type = String
  Default = 'NONE'
  Access = Locked
},
{
  Name = PTC_FATIGUE_TYPE
  Type = String
  Default = 'NONE'
  Access = Locked
},
{
  Name = PTC_MATERIAL_SUB_TYPE
  Type = String
  Default = 'LINEAR'
  Access = Locked
},
{
  Name = PTC_MASS_DENSITY
  Type = Real
  Default = 0.285 lb/in^3
  Access = Full
},
{
  Name = PTC_POISSON_RATIO
  Type = Real
  Default = 3.300000e-01
  Access = Full
},
{
  Name = PTC_YOUNG_MODULUS
  Type = Real
  Default = 1.010000e+07 psi
  Access = Full
},
{
  Name = PTC_THERMAL_EXPANSION_COEF
  Type = Real
  Default = 1.310000e-05 /F
  Access = Full
},
{
  Name = PTC_DEFAULT_APPEARANCE
  Type = String
  Default = 'adv-steel'
  Access = Full
},
{
  Name = PTC_APPEARANCE_1
  Type = String
  Default = 'adv-steel'
  Access = Full
}

}

Hi,

insert the definition of adv-steel color into global.dmt file and ... you are done.

I did exactly what you said but it's not working...

Hi,

please put into zip file your Creo part and global.dmt file and upload zip file using Browse button. I will check your data.

Hi,

I followed below mentioned steps.

• start CR3 M120
• open heinopalikka.prt
• remove all materials from the model
• save model
• exit CR3 M120

• I do not have PRO_MATERIAL_DIR option defined in config.pro
• CR3 M120 installation directory ... E:\PTC\Creo3_M120
• I created bfacj.mtl file in E:\PTC\Creo3_M120\Creo 3.0\M120\Common Files\text\materials-library directory ... I copied its contents from your original post
• I modified global.dmt file in E:\PTC\Creo3_M120\Creo 3.0\M120\Common Files\graphic-library\appearances directory ... I added adv-steel color at the end of file (55 lines copied from your global.dmt file)

• start CR3 M120
• open heinopalikka.prt
• add and assign bfacj material
• finished

AWESOME!

My problem is solved.

I think that the problem occured beacuse I had not created bfacj.mtl file in E:\PTC\Creo3_M120\Creo 3.0\M120\Common Files\text\materials-library directory. Now all the colors are correct. This saved my day!

Thanks Martin!

Hi Martin,

I know this is from over a year ago, but I am having trouble with the solution in this post.

I edited the .mtl file to include the  PTC_DEFAULT_APPEARANCE. I used one of the appearances that was already defined in our global.dmt.

It worked at first as I was assigning the material to new parts. But the next day when I started a new session, the appearance was overwritten to be white. When I go into the properties of the material and go to the appearance tab, the default appearance somehow got overwritten to be white.

So for example. There was a ptc_gold appearance in the golabl.dmt. I edited our .mtl file for our gold material so that the default appearance would be ptc_gold. So at first when I assign gold, the parts would be yellow. But the next day the parts would be white.

No idea why they are becoming white.

I am planning on creating a new community post for this problem.

What version and build? You are the second person today to say there is an issues with assigning colors in the material files. It may be a bug in the build of Creo.

Creo 3.0, M110.

Won't make the change to Creo 4.0 for a few months.

Thanks

Hi,

I tested assigning .mtl file color inCreo 3.0, M110 with success.

In my E:\PTC\Creo3_M110\Creo 3.0\M110\Common Files\graphic-library\appearances\global.dmt file there is gold_ptc color. No ptc_gold color is present.

I attached bronze_mh.mtl file I used during testing.

If I changed color name in bronze_mh.mtl file to non-existing color name (I edited file in Notepad++), created new part and assigned material ... I get white colored model.
