Materials Bugs?
-
I'm having trouble purging materials as well. Got a fairly large model consisting of many components. Originally used photos to mass/build the components; now I can't get purge the images. I'm allowed to purge, delete etc. but when I reopen the model, the images reappear in the materials list, even tho they are not on the components. I've got a gazillion components and don't even remember where the images are - grabbed from multiple older projects, so individually going through and moving the original image to a different folder to break the path isn't a sensible option. How do I do a definition purge? is there another option? Thanks!! C

Its a little unclear what is happening. But probably you need to purge unused components also.
definitions = Sketchup.active_model.definitions definitions.purge_unusedhttp://code.google.com/apis/sketchup/docs/ourdoc/definitionlist.html
Then once you have removed the components that are not being used, then you should be able to purge images and it will remove all unused images.
Unless of course your questions were not ruby based? If you want to do it manually, there is a purge option in Window > Model Info > Statistics > Purge Unused
And that will clear all unused components, materials, and layers.
Hope that helps,
Chris

Thanks for responding, Chris. I didn't realize I was in a ruby question forum -- ran into the problem and accessed the forum through my model/help portion,which brought me here. I must admit, rubies are beyond my comprehension/skill level.
If its okay to continue, tho, I'm still using the components, just no longer need the photoshop image/texture that I used to make the components. Didn't realize the problem until my main model started becoming really sluggish. Upon investigation I found that, despite purging materials in the main model and purging in individual components, the image texture material doesn't actually purge. It appears to purge but when model is purged, saved and reopened, they are back in the materials-in-model list. Really slowing my work down. I'm happy to download and try a ruby if there's one to help this (along with instructions). Or should I move to another part of the forum. Help!
Thanks -- C

its ok, we can split this out into a new tpoic later if we need.
It sounds like posibly you still have some of the photoshop material inside the component perhaps. You would need to make sure that all faces that have the material aplied to it (front, back, hidden) have the material completely removed.
Do you have a model or compoennt that shows this issues that you could upload?

Great - thanks! Here's a component from the larger model, which is composed of some smaller components. Apologies for the messiness and large size -- its always a work in progress!
Thanks again -- CCore bldgs4-render.skp

hmm... I'm not sure what the problemis.
I found four materials in the model. One was the active material, and when I selected the default material instead it was purged. Now it's three materials left. One Red and two green.

Thanks for looking at this, Thom Thom. I think what happens has something to do with a link to the original file. On my computer it still shows up as having 36 materials, 8 of those materials are image based textures. I work on a network and have grabbed these textures from throughout the network. I've been able to clean up some of the components by moving the original image file location.
I didn't have this situation before (earlier versions of SU) and think it must have something to do with dynamic components?? I could be way off base -- and please pardon my ignorance - I'm hopeless when it comes to technical things.
Thanks -- C

Here's my screen shot of the materials that appear on my model (same one I uploaded).
Thx -- C

hm... maybe it's a V-Ray bug. After purging all materials. Open the V-Ray option window and close it before you save your file.
Optionally, open the V-Ray material editor and purge materials from there as well.

ThomThom, you rock! That took care of the issue on this model. Thank you so much and have a Happy Thanksgiving! C
