Materials missing

Materials are missing in V7 on my laptop. I cannot open the Materials panel. The Materials command executes but nothing happens. Materials is on the list of panels which opens when the “gear” icon is clicked. Is there a setting which needs to be altered? Any other suggestions? Example file from the laptop: NoMaterialsDC01.3dm (2.1 MB) Materials are present in V6 and V8 WIP on my laptop and on my desktop which is running the same version of V7.

Added: The materials column is visible in the Layers panel but I can’t do anything with it.

Solved: I had disabled the Render Development Kit UI. Enabling it and restarting Rhino solved the problem. Wild goose chase of the morning but the goose was caught.

It is not obvious that a plug-in which has “Development Kit” in it’s name is needed for a core Rhino function.

Hi David -

Just wondering - did you actively disable that yourself, and, if so, what problem did you solve doing that?

Materials are things for rendering.

Anything rendering related is built on the RDK: materials, textures, environments, rendering panel, render engine integration, etc.

I disabled the Render Development Kit UI plugin (along with numerous other plugins) when I was diagnosing the reason my computer was very sluggish. It turned out to be Windows updating related, nor Rhino related. I didn’t re-enable it since I’m not during any development of rendering capability.

I understand that materials are things for rendering. That is how I found the problem.

It is probably a matter of semantics but my assumption was that a “development kit” is for use by a software developer and not something that is needed to execute released software.
