I tried to make a model for cutting plywood

First I am going to make a version compatible with V-ray 3.4 and Corona render version.
I want to make the converter materials V-ray <==> Corona.

Yes. It's possible. I will add in the next update.
Before, You can use "Global subbdivs mult" in DMC sampler, and use light inside the components.

Any way to get it to work in reverse as well???

Look at my new plugin "Ithil Render Tools". He has two similar ways:
Import all VRMAT from folder
Replace all VRMAT from folder

Yes. This version is only for v-ray.

Greetings to everyone! Im glad to introduce my new plugin to you guys.
It's the first serious project to me and i started learning Ruby specially for this one=)
After i ran from 3DS max to SketchUp i got lack of some options needed in my daily work.

This plugin was called to help you with this routine work.
Most of simple materials are now create with just one click. Moreover, all similar materials having different color can be grouped and tagged and you can work with them using just one button.

For example: all plastic toys in kids room , all books, pencils on the desk, all magazines and etc. Imagine if you have to set up each of these materials?

Now, with this plugin you can automatically set them up without any problems!

This plugin also has a block of scnene materials analyzis and you can also search incorrect materials with wrong textures.

Plugin can rewrite paths to texures and proxies if you need to change your PC.
Creates a report about lost materials and helps to find them and get back!:D

And finally a cherry on top of the cake - copying and drag&drop method of all maps in scene.

If you know what the procedural map is, this plugin will simplify your life!

Watch the explaining video and read manual below!

I hope my new extension will save you a lot of time!

Thank you!

Hi All!
This plugin helps to finde and remove invisible polygons/components/groups. Not visible objects are transferred to the new layers. If you want this layers can be removed together with its contents.

Test type:
Full - check the visibility of polygon (component) in addition to 5-axis type with the bottom image. The most accurate / slowest method
Camera - the same, but checks only one direction from the camera. The fastest method.
Short - blue, green file axis and axis of the camera.

Visibility of components / groups checked by 8 points - the corners of the bounding box. If you see at least one point of the component can not be hidden.
Visibility polygon is checked only for points. Not for the area.

Menu
Extensions(Plugins) >> Ithil Tools >> Hide Invisible Polygons and Component

Hi All!
I'd like to present my new script for SketchUp and SUbD.

It helps to work with the plugin SUbD too.
This plugin for checking topology mesh with support SUbD poly.
The script color polygons depending on the topology.
You can analyze your mesh and find the topology errors.
And you can use the "Select > All with same Material"

Menu
Plugins(Extensions) >> Ithil Tools >> Poly Checker

%(#FF0000)[Important!
This script rewrite your materials!
If you have material on the mesh, the script will warn about rewrite.]

• Trianglee"Brown"
• Correct SUbD polygon "DarkOliveGreen"
• Face with 5 or more points "OrangeRed"
• More than two faces connected to edges "Purple"

You can customize the colors changing in the script code
