@m_adam Thanks for the clarification.

@m_adam Yay thank you very much! Was almost ready to compromise with the default color.

Will use the Q&A functionality, excuse me for the posts so far.

Warm regards,
Georgi.

One thing that wasn't mentioned.
All the children objects seem to inherit the properties from the base object. If I set the base objects properties with the code in my previous post, the spline object will receive them.
Maybe there's a way to tell some objects to inherit and others to not?

Hey guys,

I would like to disable the orange highlight when the sub-objects of my ObjectData plugin are selected.
I found how to disable this for the whole application through Edit->Preferences->Viewport Display->Object Selection->Outline but I would like to do this only for my plugin's objects.

Is that possible?

Georgi.

Hey guys, i'm on R23, Windows, C++ and I have an issue setting ID_BASEOBJECT_USECOLOR.
Basically I have a spline object as a sub-object of my ObjectData plugin which I want to have a solid color.
In GetVirtualObjects() before inserting this spline under my cache root, I use the following:

                        splineObject->SetParameter(DescID(ID_BASEOBJECT_USECOLOR), ID_BASEOBJECT_USECOLOR_ALWAYS, DESCFLAGS_SET::NONE);
			splineObject->SetParameter(DescID(ID_BASEOBJECT_COLOR), Vector(1,0,1), DESCFLAGS_SET::NONE);

But this doesn't work...
Also tried setting with the ObjectColorProperties struct but no luck:

                        ObjectColorProperties props;
			props.color = Vector(1, 0, 1);
			props.usecolor = ID_BASEOBJECT_USECOLOR_ALWAYS;
			splineObject->SetColorProperties(&props);

Any ideas what I'm doing wrong?

EDIT: In edit mode I manage to do set them separately for each of my objects, so I assume it's possible.

Thank you for the attention!

@zipit Oh no worries you provided great support to get me started. As someone had suggested will also write you guys a more detailed email about the next representations I plan on implementing.

Georgi.

Ok resolved this by making the following connection TextureTag->Material->Shader->VertexColorTag and inserting the TextureTag in my object.

Going to close this. Thanks for the support.

Hey guys, it was suggested to me that the vertex color tag is designed to pass data to the renderer not the viewport. And the reason my colors were showing up using the paint tool was because it overrides the viewport. Is that correct?

Also one of your tutorials showed how to create a Material with a vertex map using a vertex color tag, so I tried that. And applied the Material to my object and the colors showed up. So perhaps this is the "correct" way to use the vertex color tag for representation in the viewport? Achieved this through the UI but I assume there's a way to do it programmatically. correct?

Thanks for taking the time!

@maxon Hey guys, one more update.
Edited my code so that I allocate the full PolygonObject in GetVirtualObjects(), place it under the cache, and just modify it in Draw(), without using DrawPolygonObject()
Managed to get the per vertex colors to show when I select my object, click "c" so i can get the edit mode and see the cache. Then I select the PolygonObject in the cache with the per vertex color tag and double click the tag as if I'm editing the colors. That's when my colors show up.

Any ideas how to get them without going into edit mode and double clicking the tag?

Regards,
Georgi.

@maxon Hey so the crashing was because I was looping out of bounds it seems. Corrected my code like so:

               BaseTag* tag = polygonObjectToDraw->GetTag(Tvertexcolor);
		if (tag == nullptr) {
			tag = VertexColorTag::Alloc(polygonObjectToDraw->GetPolygonCount() * 4);
			VertexColorTag* vcTag = static_cast<VertexColorTag*>(tag);
			vcTag->SetPerPointMode(true);
		}

		VertexColorTag* vcTag = static_cast<VertexColorTag*>(tag);
		VertexColorHandle handle = vcTag->GetDataAddressW();
		for (Int32 i = 0; i < Int32(polygonObjectToDraw->GetPolygonCount()); i++)
		{
			VertexColorStruct vcs;
			VertexColorTag::Get(handle, i, vcs);

			for (int p = 0; p < 4; p++)
			{
				vcs[p] = maxon::ColorA32(1.0f, 1.0f, 0.0f, 1.0f);
			}
			VertexColorTag::Set(handle, i, vcs);
		}

		polygonObjectToDraw->InsertTag(tag);

		baseDraw->DrawPolygonObject(baseDrawHelp, polygonObjectToDraw, DRAWOBJECT::NONE);

Still this doesn't use the color i've specified, but rather the default grey.
