Override TCA config for imageManipulation/crop for only one content type (CType) - typo3

Question

I have three type of content elements (tt_content|types) which all use an image-column with each one FAL-relations for one image.
I'd like to use for 2 content elements the type = 'imageManipulation' (Docs) with 2 different configurations and for one just the image as it is.
Since the type = 'imageManipulation' is defined normally for sys_file_reference, so for all usages.
Is it possible with TCA overrides to archive different configurations for different content elements?
I tried a combination of columnsOverrides and overrideChildTca, but this doesn't work in the moment:
<?php
defined('TYPO3_MODE') or die();
(function () {
if (is_array($GLOBALS['TCA']['tt_content']['types']['mask_teaser_hero'])) {
$GLOBALS['TCA']['tt_content']['types']['mask_teaser_hero']['columnsOverrides'] = [
'tx_maskproject_teaserimage' => [
'config' => [
'overrideChildTca' => [
'columns' => [
'crop' => [
'label' => 'LLL:EXT:lang/Resources/Private/Language/locallang_tca.xlf:sys_file_reference.crop',
'config' => [
'type' => 'imageManipulation',
'cropVariants' => [
'mobile' => [
'title' => 'Mobile',
'selectedRatio' => '4:3',
'allowedAspectRatios' => [
'4:3' => [
'title' => 'LLL:EXT:lang/Resources/Private/Language/locallang_wizards.xlf:imwizard.ratio.4_3',
'value' => 4 / 3
],
],
],
'desktop' => [
'title' => 'Desktop',
'selectedRatio' => '16:9',
'allowedAspectRatios' => [
'16:9' => [
'title' => 'LLL:EXT:lang/Resources/Private/Language/locallang_wizards.xlf:imwizard.ratio.16_9',
'value' => 16 / 9
],
],
],
]
],
],
]
],
]
]
];
}
})();
I first thought about Typoscript TCEFORM:

But this would also appear in each content element.

Answer 1

I found the mistake. The TCA override is correct. But the type was not.
I use EXT:mask_export for the content elements. In the example from the question I override the content elements which EXT:mask adds. But the exported content elements are different content elements.
The correct one is:
<?php
defined('TYPO3_MODE') or die();
(function () {
if (is_array($GLOBALS['TCA']['tt_content']['types']['myextname_teaser_hero'])) {
$GLOBALS['TCA']['tt_content']['types']['myextname_teaser_hero']['columnsOverrides'] = [
'tx_myextname_teaserimage' => [
'config' => [
'overrideChildTca' => [
'columns' => [
'crop' => [
'label' => 'LLL:EXT:lang/Resources/Private/Language/locallang_tca.xlf:sys_file_reference.crop',
'config' => [
'type' => 'imageManipulation',
'cropVariants' => [
'mobile' => [
'title' => 'Mobile',
'selectedRatio' => '4:3',
'allowedAspectRatios' => [
'4:3' => [
'title' => 'LLL:EXT:lang/Resources/Private/Language/locallang_wizards.xlf:imwizard.ratio.4_3',
'value' => 4 / 3
],
],
],
'desktop' => [
'title' => 'Desktop',
'selectedRatio' => '16:9',
'allowedAspectRatios' => [
'16:9' => [
'title' => 'LLL:EXT:lang/Resources/Private/Language/locallang_wizards.xlf:imwizard.ratio.16_9',
'value' => 16 / 9
],
],
],
]
],
],
]
],
]
]
];
}
})();
