Mesh indices are not passed into trianglePredicate

[querielo]

There is an issue with the trianglePredicate function. Currently, the function only accepts points as arguments, but in the case of a model with a custom vertex shader or with masked polygons, it is not possible to filter triangles based on their indexes or vertex parameters.

Workaround: redefine _intersectTriangles so mesh indices are passed into trianglePredicate.

Thank you for your consideration and I hope to see this feature implemented in future releases.
