Hi,
I had a long list of imaginary / dreamed plugins, but it's reducing fast this days, due to your hard work... But there are still some interesting ones not already done, so I dare post a request!
As a lot of architect, I'm really fond of a clay render style, directly whitin sketchup or for a picture. Solutions exists, for example in Vray, to overwrite all the material before the calculation, but it also kill, logically, all transparency parameters.
So, what I'm looking for is a plugin (let's call it 'clever clay' mode...) that will be able to overwrite in one operation all the material, but keeping the transparency information (for example by creating 2 new materials, one simple gray for all the solids, and one transparent for the rest). Here are some picts to illustrate the idea.
In fact, there is already scripts able to do things close to what I'm looking for, and I think minor modification can make the trick...
For example Global material changer works really fine, but on a complex model it's a bit hard, and long, to select all the materials one by one, regarding to their nature, transparent or not. There is maybe a way to adapt it...
The way Grey Scale works is also interesting in term of interface (a simple switch), but in that case the only information modify is the color range, not the texture.
Finally, the result should be a mix between hidden line and monochrome mode in Sketchup.
For presenting quickly a project, with selected informations, such a ruby will be really great, allowing to show only the effect of the sun light going t for example.
Hope it will inspire you !
