    Hi,
    I’m having a trouble when I make a test for Raycasting in VR mode.
    I created some objects in Blender Objects
    The yellow cube is at the origin (0,0). The position of controller is used as a origin of raycaster. Raycaster’s direction is set by a constant vector3 (0,-1,0). (I want to ray to the plane). Code.
    To check the result, I printed the controller’s position and the intersection to console. Result
    As you can see in the picture, the intersection object is got only if Y coordinate is positive. If the Y coordinate is negative, the result will be empty.
    Is there any problem in my code?

    Best regards.

    Hi,
    I believe this issue happens because the coordinate system in Verge3D is different (we use OpenGL/WebGL-based). X Y Z in Blender becomes X Z -Y in Verge3D. Thus, X the same, Y points UP, Z points in the negative direction compared to Blender’s Y.

    Hi Alexander,
    Thanks a lot for your response. I found my problem, the direction of raycaster is set correctly with the coordinate system in Verge3D (X Z -Y), however, the origin is achieved by puzzle that seems to be in Blender coordinate system (X Y Z). It leads to inaccurate results.

    Thank you so much.
