Hi FME community.

I am trying to color my 3D object based on its fme_color attribute but I don't know how to do it.

Currently fme_color is set as cyan. So, if I can how this as 2D in the Inspector, it shows as cyan. However, if I switch to 3D, it becomes gray. I think this is a default color. I looked at the Front Appearance Reference and this setting is set as <inherited_or_default_appearance>.

If I can set the Front Appearance Reference as same as fme_color, then this 3D object will be cyan color. I used AppearanceSetter to manually set the Front Appearance Reference but I don't know how to change it with transformers.

If someone who knows how to do it, please share your knowledge.

Thank you in advance.

Hiroo

Hi @hirooimaki, you can use the AppearanceStyler to create a set of attributes for appearance based on attributes of incoming feature (e.g. "fme_color"), then set the appearance to a 3D geometry with the AppearanceSetter.

In the case, you don't need to set color/texture parameters in the AppearanceSetter.

Thank you @takashi again. I could make it work. First I exposed fme_color using AttributeExposer and use it in the AppearanceStyler. That was tricky! I thought I could assign fme_color in the AppearanceSetter somehow. I attached my workspace image and my test 3D model with colors here (sorry about the Japanese description!)

Good to hear.

 

Tip: In the case, you could also expose "fme_color" in the Format Attributes tab - reader feature type, without using the AttributeExposer.
