Colouring components
-
Hi Guys
Can anyone tell me why when i am trying to colour components some of them will colour the whole component with one click and others wont so i have to open the context and colour each individual face.
Cheers

Faces inside a component or group can have materials assigned to them, or they can just have the default material.
If you paint a material onto a component-instance or a group then any face inside it that has the default material, is displayed as if it were painted with that new material [it actually still has the default material]. If a face inside it has already got another material it still displays using that original material.The reason for this is explained thus:
You model a car component, you give it black tires, glass windows, chrome-trim, red/orange lights, gray seats etc, BUT you leave the bodywork in the default material.
Now you can have several instances of the same car component in your model and paint then different colors - white, blue, silver etc ans they will display with those body colors, whilst keeping the other parts like the wheels consistently colors in every instance...Textured materials ought to be applied onto faces because it then allows you to use the context-menu Texture tool to adjust their position, scale and rotation etc, textured materials applied onto instances give you no control over the texture's 'mapping' and will often appear poorly...
If you are making your own components remember to think about what needs a fixed color/texture and what can be left as 'default'. Unfortunately many things downloaded from the 3dWarehouse will have been modeled very poorly - often with reversed-faces too - so you will need to fix these manually...
