Dildo won't penetrate

[metalgerm]

Hi, New to VAM. I make a scene with an environment and female, but whatever position I put her in the VAMX dildoes, the self thrusting ones, won't penetrate. If I add a dildo thru the edit scene, I can manually penetrate. The VamX self thrusting dildos only work when I use the VAMX menu and put her into certain poses, like laying back, but it will not work with any other poses. I have not changed any settings, as there are so many settings that it gets a bit overwhelming, and I feel like I will break something else by just clicking around. Please let me know any other info I can supply to help figure out what is going on here. Thanks!
