Deleting non-deletable nodes, how?

[Anonymous]

Hi,

I imported a project from Revit 2014 into Maya 2014 only to find that everything in the project now has a reflective glossiness to it. I've tried deleting the nodes in the Hypershade window, but I receive the error "Non-deletable node '#######' cannot be deleted".

The three nodes I'm trying to delete are "shaderGlow1", "particleCloud1", "lambert1".

I have searched the internet for help on how to unlock and delete locked nodes, deleting non-deletable nodes, etc. Unforunately none of the topics or scripts I have come across have done anything.

Although admittedly I know very little about programing or much about using code, all I know about code is to do when the instructions say.

Basically I just really need help on how to delete those three nodes, or if that is not possible, how do I remove the reflective glossy appearance those nodes are causing. Because I have even tried changing the values of those three nodes and its either reflective glossy are the entire project becomes pitch black.

Please let me know.

Thank you.

to be honest it´s hard to believe that one of these nodes cause the descriped behaviour. shaderGlow cannot be assigned to a geometry, particleCloud should do nothing and usually is not assigned to any geo by default and the lambert has no glossy attributes. are you sure that this are the only materials in your scene and that there is nothing else assigned? most of the time if i import geo from external sources like different cad software they have a phong or blinn shader assigned! a picture maybe helps!

beside this yes they can´t be deleted which is good. i.e. if you create new geometry in your scene it uses the lambert1 unless you assign another material if it will not be there you´ll just see a wireframe. you should try selecting all your imported geometry and assign a new lambert or other material of your choice if this doesn´t help show some pics of your scene and the hypershade!

Thank you for replying Sebastian!

I've posted a screen capture of the hypershade window and a rendered image of the project. The fourth node in the hypershade window is a blinn I added to give the wireframe contour lines, which I need as this is going in my demo reel (career hunting). I deleted the fourth node and realized that is when the project goes completely pitch black. So I un-deleted it. Is there a setting in the blinn that is causing the mass reflection on everything?

If there is I'm completely overlooking it, as I have I gone through each of those nodes and with all my tweaking nothing changes the way I want.

Please let me know.

Thank you!

yes the blinn is the "problem"! by it´s nature it´s used for reflective/specular materials so it behaves like that with default settings. you can either set the specular color to black and the reflectivity to 0 or just use a lambert material which doesn´t do any relfections or speculars.

side note: put the lambert1 back to something else than black. it´s the default material and in case you create new geometry it will appear black!

That fixed it, thank you Sebastian! I'm grateful.
