I've further investigated this. The vertices of the object are very small (it's bounding box sizes are 10mm x 1mm x 0.7mm). Could the issue be here?
If I consider common ray-triangle Moller-Trumbore intersection algorithm, it uses epsilon around 1e-7 to check for floating point errors and whether the ray is parallel with the triangle. Might this be the case? I've tried the methods directly in HitTester yet it yields the same results (bounding box is hit by the ray, the object is not).
