Help with limiting materials' RGB values ?

yitzhar

is there a plugin for setting up all the color materials in the model that
wont be over 235,235,235 (rgb) it will help for setting up for renders ..
thanks

No plugin that I know of.

However, it's not that difficult to manually fix RGB values...
It would be possible to iterate through the model's materials and adjust the RGB values to be 235 if they were >235. However, this would mean pure 'Red' [255,0,0] would be toned down ?
This one-liner does what you ask.

m=Sketchup.active_model;m.start_operation('235');m.materials.each{|a|c=a.color;c.red=235 if c.red>235;c.green=235 if c.green>235;c.blue=235 if c.blue>235;a.color=c};m.commit_operation

Seelect-All then Copy/Paste it + <enter> in the Ruby Console, and all of the model's materials are toned down so that no RGB is > 235... It is one-step undo-able.

thank you for the fast reply,
im more into makeing the white not so white ... thats meens little bit more grayer.
i started to work with maxwell plug for SU and one of the first problems that everybody
say about the slow render time is - to make all the colors not just the red to max 235,235,235.

so is what you said still work for me?
and how and where do i open the ruby script writer ?

thank you very much

Reread what I wrote...
It works on ALL materials, making the RGB values 235 maximum; thus 'toning down' the hue of every color that has an RGB value > 235.
To use this one-liner code... open the 'Ruby Console' in SketchUp [via the SketchUp > Windows menu] and the copy/paste the whole of the line of the code into the bottom area of the 'Ruby Console', then press the <enter> key to run it.
All materials are changed [it's relatively fast].
You should see the RGB change in any material you 'Edit' in the Materials Browser, if any value was > 235 it will now be 235...
It is one-step-undo-able - e.g. if you decide you don't like the changes.

You could save the one-line of text into a text file for easier use later on...
