Schema & Settings v1.1

caution

The 3D Processing Schema & Settings v1.1 are only compatible with the 3D Processor CLI v7.1.0 and newer. Settings created against the v1.1 schema will not validate with the 3D Processor CLI v7.0.0 and older !

Introduction

The 3D Processing Schema is a set of rules that represent and validate the structure and format of RapidPipeline's 3D processing functionalities.

tip

In addition to describing the structure of data, schemas apply constraints and expectations to data so it can be validated as it moves between systems. These standard definitions allow data to be interpreted consistently, regardless of origin, and remove the need for translation across applications.

RapidPipeline maintains this semantic normalization by using schemas. Schemas are the standard way of describing data processes in RapidPipeline, allowing all data that conforms to schemas to be reused across all different tools and interfaces without conflicts.

RapidPipeline 3D Processing Configuration Settings adhere to the 3D Processing Schema and are designed to achieve any 3D processing goal.

The 3D Processing Schema v1.1 is utilized by multiple RapidPipeline Software Packages & Interfaces making use of the 3D Processor:

Software Package or Interface	Schema	Description
3D Processor CLI v7.1.0 - v7.1.1	3D Processing Schema v1.1	Direct operations on the 3D Data, such as Optimization, Compression, etc.
RapidPipeline Blender Plugin v0.1.2 - v0.1.3	3D Processing Schema v1.1	Direct operations on the 3D Data, such as Optimization, Compression, etc.

3D Processing Settings

3D Processing settings are types of settings operating directly on a 3D model and are able to alter the entire structure or re-create meshes, materials, UVs, texture maps and other 3D model properties.

A set of 3D processing configuration settings in the RapidPipeline Web Platform is described as a 3D Processor Preset.

tip

The settings as displayed within the In the JSON Settings File sections are all utilizing an additional simple glTF export.

This is only needed if the given config is solely utilized with no other (export) configuration given, as the 3D Processing Schema requires at least one file export. More about file exports and settings within the export format section.

Preset Examples

In order to try out some example presets the new 3D Processor Presets in the RapidPipeline Web Platform can be utilized.

info

See the update regarding the new presets in the Product Updates section here

To download a preset in editable JSON format, activate Preview New Settings with the radio button and download the respective settings JSON files via the Actions menu:

These JSON settings files can be ingested by the RapidPipeline Blender Plugin or the RapidPipeline 3D Processor CLI.

Optimize 🚀

The Optimize category contains the main functionalities for Mesh and Material Optimization, including options for decimation, remeshing, texture atlas baking, UV aggregation, and more.

3D Model Optimization Method

Choice of the major Optimization method.

There are 2 main options to choose from:

• 🎨 Material Optimization

• 🌐🎨 Mesh and Material Optimization

Material Optimization 🎨

Main option for optimizing the model's materials, including material merging, UV (atlas) generation, Texture Baking, and more. Keeps mesh topology as is.

There are multiple options available:

• Material Merger
• Keep Materials and UVs
• Material and UV Aggregator

Material Merger

Option which merges materials according to existing material properties if possible (currently the merging method is set to "auto" = merges materials by opacity and keeps non-combinable materials separate). Optionally preserves materials with tiled UVs.

Additional UV (atlas) unwrapping and texture baking options are available via the Material Regenerator in order to project the original material properties onto the merged output materials.

Material Regenerator

The Material Regenerator makes sure the merged or otherwise altered materials are inheriting the original material properties or alternatively get assigned new materials and UVs.

The following options are available:

• Generate UV Atlas + Texture Baker
• Material Replacer + Default Material (+ Unwrapping Options)
• Material Replacer + Drop Uniform Texture Maps

Choice Between UV atlas generator or material replacer.

info

Required if Material Merger is used.

Material Regenerator + UV Atlas Generator + Texture Baker

This is the most common usage of the Material Regenerator within the RapidPipeline 3D Processor.

It enables creation of new UV atlases corresponding to the (new, merged) output materials and baking from the original input materials and meshes onto the merged or otherwise altered output materials and meshes.

This process does consider all (PBR) material properties and is able to project from material, vertex colors and other material attributes to texture maps as well as perform normal map and ao baking to capture mesh, normal and occlusions from the original data.

Mesh and Material Optimization 🌐🎨

Main option for optimizing the model's meshes and materials, including mesh decimation, remeshing, material merging, UV (atlas) generation, Texture Baking, and more.

Two main options to choose from, each has different sub-options:

• Remesher

  • Material Merger

• Decimator

  • Material Merger
  • Keep Materials and UVs
  • Material and UV Aggregator

Remesher 🌟

Remeshes the original mesh and decimates to a face target.

info

Due to the entire re-creation of the original surface, original materials and UVs can not be kept. Material Merger and Regenerator are therefore required in order to reproject original mesh and material properties.

tip

The default of 100% results in exactly the original mesh resolution of the input, as the remeshed surface is always decimated after the initial remeshing. The initial resolution of the remeshing process can be steered with the remeshing resolution setting.

The default of 100% results in the exact same mesh resolution than the input.

tip

The default of 1 is not recommended for an actual production config. We recommend at least 1,000 faces.

info

In theory, the target face value can be higher than the input, achieving a denser mesh than the original (depending on the remeshing resolution setting).

Vertices (Target)

Vertices Targets for the Decimation Operation after the initial Remeshing.

info

The vertices target can be set in addition to the face target. Whichever target is lower is respected. The vertices target is not required and thus face targets can be used in the same way as with 3D Processor v7.0.0

Material Regenerator (Remesher)

The Material Regenerator makes sure the merged or otherwise altered materials are inheriting the original material properties or alternatively get assigned new materials and UVs.

The following options are available:

• Generate UV Atlas + Texture Baker
• Material Replacer + Default Material (+ Unwrapping Options)
• Material Replacer + Drop Uniform Texture Maps

Choice Between UV atlas generator or material replacer.

info

Required if Material Merger is used.

Material Regenerator + UV Atlas Generator + Texture Baker (Remesher)

This is the most common usage of the Material Regenerator within the RapidPipeline 3D Processor.

It enables creation of new UV atlases corresponding to the (new, merged) output materials and baking from the original input materials and meshes onto the merged or otherwise altered output materials and meshes.

This process does consider all (PBR) material properties and is able to project from material, vertex colors and other material attributes to texture maps as well as perform normal map and ao baking to capture mesh, normal and occlusions from the original data.

Generate UV Atlas (Remesher)

Options for the newly generated UV Atlases. All generated Atlases are in the 1-by-1 UV space.

Material Optimization (Decimator)

Option within Decimator for optimizing the model's materials, including material merging, UV (atlas) generation, Texture Baking, and more.

There are multiple options available to pair the decimation process with:

• Material Merger
• Keep Materials and UVs
• Material and UV Aggregator

Material Merger (Decimator)

Option which merges materials according to existing material properties if possible (currently the merging method is set to "auto" = merges materials by opacity and keeps non-combinable materials separate). Optionally preserves materials with tiled UVs.

Additional UV (atlas) unwrapping and texture baking options are available via the Material Regenerator in order to project the original material properties onto the merged output materials.

Material Regenerator (Decimator)

The Material Regenerator makes sure the merged or otherwise altered materials are inheriting the original material properties or alternatively get assigned new materials and UVs.

The following options are available:

• Generate UV Atlas + Texture Baker
• Material Replacer + Default Material (+ Unwrapping Options)
• Material Replacer + Drop Uniform Texture Maps

Choice Between UV atlas generator or material replacer.

info

Required if Material Merger is used.

Material Regenerator + UV Atlas Generator + Texture Baker (Decimator)

This is the most common usage of the Material Regenerator within the RapidPipeline 3D Processor.

It enables creation of new UV atlases corresponding to the (new, merged) output materials and baking from the original input materials and meshes onto the merged or otherwise altered output materials and meshes.

This process does consider all (PBR) material properties and is able to project from material, vertex colors and other material attributes to texture maps as well as perform normal map and ao baking to capture mesh, normal and occlusions from the original data.

Generate UV Atlas (Decimator)

Options for the newly generated UV Atlases. All generated Atlases are in the 1-by-1 UV space.

Modifier

Optional additional optimization which will alter the output data according to the given modifier type.

All modifiers take effect after the Optimize and Export settings and generally try to respect the settings (e.g compression, texture map formats etc.).

However in a lot of cases the modifiers will overwrite settings which need to be altered to achieve a certain modifier goal (e.g. a certain file size or size on screen resolution etc.).

info

If no optimization settings are set, the modifiers will still optimize to the given target if needed (e.g. a certain number of MB). In that case default optimization settings are utilized.

File Size 💾

Modifier which alters the optimization settings in order to meet a given maximum file size (MB).
