I want to parent a lattice to an armature and then I would also like to weight paint it. Is this possible?
You can parent a lattice to a bone but the lattice is not a mesh so you cannot weight paint it (select a lattice and try switching to weight paint)
Maybe an amature on a simple mesh that drives a mesh-deform modifier might do what you want.
Wallem, a word of advice…
Images of your model or the blend file itself might make helping you easier - just what exactly are you trying to achieve? Is this post related to others you have made recently?
A good way to get help here is to tell us what you are trying to do rather than ask abstract questions as you have. It may be that you should not be using a lattice at all - in which case tell us what you are doing please. Asking questions like “Can you rig a lattice?” may result in the answers “No”, “Depends” or they are simply ignored. Showing a picture of your model with a question like “I want to stretch this spring between the two arms as shown in my image file below - what would be the best way to achieve this?” will result in much more useful help being posted by other members.
If all your posts in this forum are related to the same blend file/project/topic, please keep them all in ONE thread, this helps us to help you better. Pictures and blend files - always post pictures and/or blend files.
Cheers, Clock.
