Hello,
I have generated a simple attachment class with the following field
container description:
<?xml version="1.0"?>
<FieldContainer
name="HighlightMaterialAttachment"
parent="Attachment"
library="ContribDataSolid"
pointerfieldtypes="both"
structure="concrete"
systemcomponent="true"
parentsystemcomponent="true"
decoratable="false"
childFields="none"
parentFields="none"
>
DataSolid attachment that stores the actual non highlight material on
highlighting.
<Field
name="material"
type="ChunkMaterialPtr"
cardinality="single"
visibility="external"
access="public"
>
The material to be tracked.
</Field>
</FieldContainer>
Unfortunately something is wrong here because the generated classes do
not compile. I got the following error message:
1>OSGHighlightMaterialAttachmentBase.cpp
1>OSGHighlightMaterialAttachment.cpp

Can anyone give me some help on how to write a correct field container
description file for an attachment just carrying a single
ChunkMaterialUnrecPtr ?
Best,
Johannes
