I have registered thumbnail in the following way

<bean id="thumbnailDefinitionSTLpreview" class="org.alfresco.repo.thumbnail.ThumbnailDefinition">
        <property name="name" value="stl" />
        <property name="mimetype" value="application/sla" />
        <property name="transformationOptions">
            <!-- The thumbnail definition have transformationOptions mandatory -->
            <!-- But there are none for pdf, so use SWFTransformationsOptions as a dummy -->
            <bean class="org.alfresco.repo.content.transform.swf.SWFTransformationOptions">
                <property name="flashVersion" value="9" />
      <bean id="baseThumbnailRegistry" abstract="true">
        <property name="contentService" ref="ContentService"/>
        <property name="renditionService" ref="renditionService" />
        <property name="transactionService" ref="TransactionService" />
        <property name="tenantAdminService" ref="tenantAdminService" />
        <property name="redeployStaticDefsOnStartup" value="${system.thumbnail.redeployStaticDefsOnStartup}" />
        <property name="thumbnailDefinitions">
                <ref bean="thumbnailDefinitionMedium" />
                <ref bean="thumbnailDefinitionDoclib" />
                <ref bean="thumbnailDefinitionImgpreview" />
                <ref bean="thumbnailDefinitionAvatar" />
                <ref bean="thumbnailDefinitionAvatar32" />
                <ref bean="thumbnailDefinitionPDFpreview" />
                <ref bean="thumbnailDefinitionWebpreview" />
                <ref bean="thumbnailDefinitionSTLpreview" />
        <property name="thumbnailRenditionConvertor" ref="thumbnailRenditionConvertor" />


and in "web-preview.get.config.xml" have also added following code

<condition mimeType="application/sla">
      <plugin src="webpreview" paging="true">STLViewer</plugin>
      <plugin srcMaxSize="500000">Image</plugin>

<condition thumbnail="stl">
         <plugin src="stl" paging="true">STLViewer</plugin>


and in order to create a thumbnail, I am executing a script on a folder rule which is as follows

document.createThumbnail("stl", true);;


and also able to see "cm:thumbnail" child in node browser as shown in below image


But unfortunately, I am not getting the preview of files with "application/ply" mime type.


I am attaching two more images below to make you more clear with a situation


this is how my actual file with "application/sla" mime type is getting previewed. But file with mime type is not getting preview properly which can be seen in below image


And If I am performing the transformation from "application/ply" to "application/sla" it is working correctly.
