RDFramebufferPass
=================

**Inherits:** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

Framebuffer pass attachment description.

Description
-----------

This class contains the list of attachment descriptions for a framebuffer pass. Each points with an index to a previously supplied list of texture attachments.

Multipass framebuffers can optimize some configurations in mobile, on desktop they provide little to no advantage.

Property Descriptions
---------------------

.. _class_RDFramebufferPass_property_color_attachments:

- :ref:`PackedInt32Array<class_PackedInt32Array>` **color_attachments**

+-----------+------------------------------+
| *Default* | ``PackedInt32Array()``       |
+-----------+------------------------------+
| *Setter*  | set_color_attachments(value) |
+-----------+------------------------------+
| *Getter*  | get_color_attachments()      |
+-----------+------------------------------+

Color attachments in order starting from 0. If this attachment is not used by the shader, pass ATTACHMENT_UNUSED to skip.

----

.. _class_RDFramebufferPass_property_depth_attachment:

- :ref:`int<class_int>` **depth_attachment**

+-----------+-----------------------------+
| *Default* | ``-1``                      |
+-----------+-----------------------------+
| *Setter*  | set_depth_attachment(value) |
+-----------+-----------------------------+
| *Getter*  | get_depth_attachment()      |
+-----------+-----------------------------+

Depth attachment. ATTACHMENT_UNUSED should be used if no depth buffer is required for this pass.

----

.. _class_RDFramebufferPass_property_input_attachments:

- :ref:`PackedInt32Array<class_PackedInt32Array>` **input_attachments**

+-----------+------------------------------+
| *Default* | ``PackedInt32Array()``       |
+-----------+------------------------------+
| *Setter*  | set_input_attachments(value) |
+-----------+------------------------------+
| *Getter*  | get_input_attachments()      |
+-----------+------------------------------+

Used for multipass framebuffers (more than one render pass). Converts an attachment to an input. Make sure to also supply it properly in the :ref:`RDUniform<class_RDUniform>` for the uniform set.

----

.. _class_RDFramebufferPass_property_preserve_attachments:

- :ref:`PackedInt32Array<class_PackedInt32Array>` **preserve_attachments**

+-----------+---------------------------------+
| *Default* | ``PackedInt32Array()``          |
+-----------+---------------------------------+
| *Setter*  | set_preserve_attachments(value) |
+-----------+---------------------------------+
| *Getter*  | get_preserve_attachments()      |
+-----------+---------------------------------+

Attachments to preserve in this pass (otherwise they are erased).

----

.. _class_RDFramebufferPass_property_resolve_attachments:

- :ref:`PackedInt32Array<class_PackedInt32Array>` **resolve_attachments**

+-----------+--------------------------------+
| *Default* | ``PackedInt32Array()``         |
+-----------+--------------------------------+
| *Setter*  | set_resolve_attachments(value) |
+-----------+--------------------------------+
| *Getter*  | get_resolve_attachments()      |
+-----------+--------------------------------+

If the color attachments are multisampled, non-multisampled resolve attachments can be provided.
