---- Multi-Texture usage ----
(from plugin version 2021.1.4 - 12.16)
Octane Multi-Texture allows to apply randomly multiple textures to an object.
1) Add images to the image list.
Use the Add images button, and select 1 or several image files
2) Apply the material to some objects
3) Use the 'Refresh objects' button in the Reference Objects rollout.
This will check the geometry settings and provide a 'Fix issues' button to configure the Octane Geometry modifier correctly automatically.
You can choose one of the 2 ways to differenciate faces for the random texture assignment:
-Using the Material IDs.
-Using the Polygon connections.
This creates internal IDs for each group of connected polygons.
* Seed: Base for random numbers generation.
* Use instance ID
This allows to have different random textures on several object's instances.
If disabled, all instances will have the same randomness.
-Removing images from the list:
Select one of several images, and use the context menu (right click) and choose 'Remove image(s)'
In this menu, the 'Explore image folder' opens Windows Explorer at the folder location.
The Multi-Texture is a wrapper using Octane Image Tile, so there are the same output settings available (power, color space, etc..)
The object list provide a context menu for selected objects, and allow to change the geometry assignment type (Material ID / Polygon connection)
Notes:
-When using copies of objects instead of instances, the instance IDs will the same by default.
You can assign unique Instance IDs globally for all reference objects, so they will have a different randomness (object list context menu).
Note: Drag and drop of external image files is partially supported. You currently need to drop files on the right of the 'Add images' button, not in the list itself.
This will be fixed in future releases.
Samples :
Multi-Texture_sample1_MtlID.max
using the default Box (witch has 6 different material IDs), each side use a different random texture.
Note that the teapot has both different material IDs, and separate parts. So you can use both methods to differenciate faces.
Multi-Texture_sample2_connectedPolys.max
The first object (tiles1_connectedTri) do not have material IDs, and faces are grouped by their connection.
The second object (tiles2_mtlIDs) has some material ID, so both methods can be used.
