I used the Mesh-Warp filter and it worked already very nice. However, in a new project I cannot activate/modify it at all. Going back to the original file I’m still able to play back the animated Mesh-Warp but I’m unable to modify it further. So it seems that this filter is anyhow broken. Is there any possibility to repair it?

Are you able to copy the Mesh_Warp module in the network and modify the copy? Has this happened previously? You should contact support to have a look.

Thanks for your reply. Well, I contacted the support and we found out the reason: I simply forgot that time to also activate the Transform button. I thought it would be sufficient to activate the Mesh_Warp module in the network and that this would allow to modify the Mesh_Warp. However, this obviously is not the case.
