Problem With Attaching Items Inside a Cylinder

[Apollo13]

I've created a simple open cylinder, whereby the sides and end pieces have colliders (convex).  However, I am unable to attach items inside the cylinder.  In the first image, it shows the colliders.  The second image shows that the colliders have no meshes to render and they are all convex.

This image shows that the colliders are created in Blender.

Finally, the part displayed in the VAB, where I cannot attach even a stock light inside.  I can attach it outside, though.

I want to attach items to the inside surfaces.    The CFG file allows surface attachment:

// attachment rules: stack, srfAttach, allowStack, allowSrfAttach, allowCollision
attachRules = 1,0,1,1,0

What am I missing?

Noob here but I'll try anyway: On your screenshot, I'm not seeing a mesh in the mesh collider box below material.  Mine do.

Is that the issue?

try it with box colliders, and more thickness.

I'm not sure if this is what you're running into, however something to keep in mind is that the VAB will still try to orient the part that you're attaching as if it's connecting to the outside. That is, by default it'll attach inside the wall, rather than facing inward toward the center, so the player will always have to rotate the part around as they're attaching it. The VAB logic just doesn't really expect people to attach things to the inside surfaces of cargo bays and the like. The attachment position itself will be correct, it'll just face the wrong way unless the player rotates it.

thank you for your response.  That could be the problem.

Also try without angle snapping ("c").

Colliders NEVER have rendered meshes.  If you have those in your mod, remove them.

I'll try box colliders.  However, the walls are not rectangular shaped.

I'll test that.

Yet, there are stock cargo bays where you can place items against walls inside.
