[Plugin] Remove group materials, leave geometry material

thomthom

Anyone notice a REAL dramatic difference in parsing after running this script? Whenever I have a really long parse, I'll run this script, but it never really seems to speed things up. Is it just me?

Yes, there's a VERY big increase in parsing time.
At the end of the script it tells you how much was replaced - what does it tell you? It could be that you are running into other issues. Lots and lots of groups and component definitions eats time as well, more if they are deeply nested.
But groups/component materials eats the most of the time.

The reason it's so slow is that when VfSU runs into group/component materials it has to internally create a new copy of that object and in order to get the proper UV mapping it has to apply all the group/component material to the faces contained inside - then afterwards restore it. And that takes an insane amount of time.

thomthom

FYI: I have an imported Revit model that has 777 component definitions and ~2500 component instances. Totalling of about 70-80000 faces. This model takes 1-2 minutes to parse before it opens the render window and begin rendering.
And this model has no material at all - just plain default. If I had group/component materials applied the computer would tie a bucket of brick around itself and jump of the bridge...

Must be other issues. It's really frustrating that there is no parsing progress bar. Or, the ability to have it only have to parse once. Seems like since it is just storing UV data, that as long as you don't move the camera, you should be able to reuse the same data. Nothing is more frustrating than having to wait for every test render.

On another note, I tried to open SS's Snowberry model (which took about 5 minutes to open) and render with VfSU (with no materials)......after 30 minutes of parsing, i just gave up.

But you need to parse the whole lot again anyway to check if anything has changed.

The next version should see some improvements though.

That model is up in the millions in face count isn't it?

Hi all.
Sorry for the delay, I will see what I can do.

Do you still need to do this with the new Vray? (v1.488) I seem to encouter problems when with Vray 1.488 after running this script (not 100% this was the culprit)

Cheers

No - Only with 1.05.30 and older. The new one might actually be faster if you use group/component materials.

I can not run the remove CG materials plugin, is the link broken or corrupted?

You have problem downloading or using the plugin?

[FEATURE REQUEST]

It's a useful plugin, until I found it, I had to remove all materials from selection using This Plugin, then reassign materials only to geometry inside group/component -often I have different materials on faces.

I would like some features to this plugin: Now, with so many plugins, the Plugins Menu gets really crowded, so submenus are welcomed. So, I was thinking if you could add a feature to this plugin to remove all materials, something like this:

REMOVE MATERIALS
>Remove CG Materials
>Remove ALL Materials
In this way, instead of having two entries for those two plugins, I would have one single menu with two child options.

Also, if the inputbox could be disabled, to speed-up the usage. I never replaced CG material using the inputbox, so for me is just a unnecessary mouse click Actually, I'm curious if anyone uses that feature.

Thank you.

The link to the rapid share download doesn't work, can some post the script?

This plugin should do what you want: http://www.keepingmyhandin.com/Downhome/Sketchup/material_maintenance_2

Thank you MyHand. Very useful plugin which I haven't seen it before.
