EXPORT FROM CATIA (.3DXML)
Add Catia material to differentiate different parts.
Meshroom VR uses the different materials applied by Catia to your model to identify the different parts. On each part, you will be able to drag’n’drop a Meshroom VR material.
To identify which parts have material assigned:
Select one part in the tree.
Find Apply Material icon in the toolbar at the bottom of your screen.
Click on it.
Select required material and click on Apply material > Ok
You can see in the tree which material is applied
*It is those colors and textures that Meshroom VR will use to identify the different parts of your model.
Do not triangulate too much!
Unlike in rapid prototyping, low tesselation provides the best results in VR.
To set the tesselation level:
Go to > Tools > Options.
In the window opened, go to General (left side) > Display.
Select tab performance.
In 3D accuracy, check «fixed» and insert your tessellation value. (ex: 0,20)
Then, go to General > Compatibility.
Select the tab 3DXML.
Check Xml Tesselation.
Click on OK.
*By exporting your model, you will convert it to a triangle mesh. The quantity of triangle generated is called tesselation.
Export only what you need!
Remove all useless objects from your export. If you want to validate the exterior shape of a design, it would be useless to import all the machinery hidden inside!
To export your 3D project:
Go to > File >Save as.
Check on Save.
*We have selected 3DXML because this is a polygonal format with materials included achieving an import and export faster.
