It works.
But as I used your code in my plugin, it crashes the same way

Then the problem has to be in your plugin.
Do you know how to use the debugger?
The error you get from it might help you figure it out.

Edit-- FYI
I have to correct myself a bit.
That stuff I was saying about the subdialog is for the older type of ToolData plugins.
I think you're using the newer DescriptionToolData plugin. Which uses the .res file. And is a bit different from the older ToolData plugin.
I forgot that there was two different versions of the tool plugin.

I don't have the Remo code in my plugin, like you have.
It is in a separate file that I include at the start of my source code, like this:

#include "c4d.h"
#include "c4d_symbols.h"
#include "tpolypaintfrommaterial.h"
#include "c4d_helpers.h"
#include "remo_sampler.h"

Could it be because of this?

Doing some simple detective work I found out that what is causing the crash in SampleColorAtVertices is the line:

Sampler smpl;

If I place a return INIT_SAMPLER_RESULT_OK; before this line, no crash occurs.
If I place a return INIT_SAMPLER_RESULT_OK; after this line, the crash occurs.

Hi
This seems to be a problem in the constructor.
Sampler::Sampler() { ... }

But it is imposible to say exactly what causes this crash without knowing what was changed in the code.

Have you changes something in this code section ?

  
	AutoAlloc<VolumeData> vd; //Owning ptr 	  
AutoAlloc<TexData>	 tex; //Owning ptr

Because this will auto alloc vd and tex.

Well then it will be cause by some changes in the constructor.

Of course you can send it over e-mail.
Even better just place it on github.com

Since you're having so many problems with this. I decided to create a DescriptionToolData plugin myself.
I used your Message() code for the getting the object in the linkbox gizmo.
And I used the same Sample class code I sent you in my CD plugin.
I also used a separate .h file to host that code. Using #include "sampler.h" to point to the code from the plugin's .cpp file

It all works fine for me and does not crash at all. I can't undestand why you're having so many problems with it.
Would you like me to send you my tool plugin?

I think yes.

Or just PM me here, whatever you want
Note: I do not ready my e-mails often. Some times for many days.

Thank you to both.
I will try take a look at Scott plugin and compare it with mine first.
I hope I find my mistake (I'm assuming I must be doing something wrong).
If I still don't manage to fix it, I will send you my code through PM, Remo.
Ok?

So, if you don't mind, Scott, I would gladly take a look at your plugin.

In the meanwhile, let me tell you guys one thing that may help pinpoit the problem.
Xcode is giving me a warning in the line:

GeDynamicArray<Colors> colors(pcnt);

The warning is: Template argument uses local type 'Colors'

What is this?!?
