Equivalent color settings in Blender with Autodesk Navisworks I want to get the equivalent color settings in Blender by comparing RGB values in Autodesk Navisworks color properties from Material tab when an object has been selected. 

Here are the color properties values from Autodesk Navisworks:



So far I have managed to achieve the equivalent color settings in Blender for Diffuse, Specular, and Emissive.

Here are the auto-generated Phyton code by Blender's scripting tool when I change the color in the screenshot below:



Python codes generated:

bpy.context.object.active_material.diffuse_color = (0.442353, 0.331765, 0.294118)
bpy.context.object.active_material.specular_color = (0.5, 0.5, 0.5)
bpy.context.object.active_material.volume.emission_color = (0, 0, 0)


Questions:


Where can I set the RGB values for Ambient in Blender?
How do I adjust the Shininess and Transparency in Blender?


Thank you.
Expanding my comment above: yes, you're using Blender Render.

About 1)

Ambient color should be what is set in the World settings, here:



And you can level the amount of ambient each material gets with this:

About 2) I think you need to set your material's specular:

You can choose color, intensity, shader type, and you can also use a custom-defined color ramp, if needed, here:

Of course, being Blender Internal a scanline renderer, it is not targeted to ultra-realistic results. 

I don't know Navisworks at all, so it could be a similar system, or not. Maybe others will help better than me in this respect.

Blender's Cycles, instead, is a very good PBR renderer and it allows ultra realistic results, if needed, but its materials are completely different, and based on nodes - in that case, start here: https://www.blender.org/manual/render/cycles/materials/index.html
