Vex error with MOPs_Move_Along_Spline

Post by briankulig »

MOPs_Move_Along_Spline is throwing a vex error in the 'apply_new_goals' node inside of it. It does it in the Mops-master/examples/move_along_spline_1.4.hip in Houdini 18.5.351 on both Windows and Linux (ubuntu).

This is a known bug in 18.5... they changed the VEX signature for primuv_convert(). If you download the latest Experimental build of MOPs, 1.2.4e as of this writing, the bug should be fixed.
