Once you have completed photogrammetry, and have produced an Alembic, ST Map(s), and optional Mask Mesh, you can run the PROCESS step to create PBR textures.
Select the row and click Queue to configure how the PROCESS step will run.
This will launch a window form to fill with the required information.
The Light system has been pre-filled from when the job was created. It can be overwritten if the measurements were wrong, however if the new light system has a different number of lights to the initial configuration, Marso may not work correctly.
The Exposure Preset defines how your raw files should be processed. These can be created from a single Calibration Image captured with the same setup as you took the scan. See Calibration for more information.
Then provide the Mesh File and ST Map produced by photogrammetry. You can optionally provide a Mask Mesh if there is geometry in the scene that can occlude the subject from any camera angle.
The final settings are:
UV Bleed: we recommend leaving on by default.
UV Resolution: Select the desired UV texture resolution.
If multiple are selected, the material will be processed at the highest resolution and smaller textures will be down-sampled from it.
Shaders: Select the desired texture workflow
Clicking Save to save changes, or Cancel to discard changes.
The changes will then be visible in the “Details” Panel. Once a job has been configured, the status will become READY, meaning it is able to be queued. There should also be no missing fields, coloured red, remaining.
Click Start to begin processing the asset.
Processing can take upwards of 6 hours, depending on the mesh size, source photography resolution, and the number of cameras and lights. See Processing Times.
📦 Results
Upon processing completion, the Results button will be made available and clicking it will open the directory storing the material textures:
The results directory for each completed job will present the following contents:
A directory named Textures, containing folders for each supported render engine (currently just BlenderCycles). PBR textures will be generated for the Diffuse, Roughness, Specular and Normals channels in EXR, PNG, and JPEG formats.
☠️ Interrupting a Job
A running job can be interrupted with either the Stop/Skip or Pause buttons. Both will keep any progress up to the current step. Pause will return it to the front of the queue, while Skip will remove it from the queue and start processing the next queued item.
