Error trying to use runtime mesh component(from a plugin)

MichaelEvans · March 3, 2017, 8:32pm

consistent crash reproduced in clean project, this line of code is what’s causing the crash.

mesh->CreateMeshSection(index, verts, tris, normals, uvs, vertexColors, tangents, true, EUpdateFrequency::Infrequent);

Access violation - code c0000005 (first/second chance not available)

I’m not sure what all of this means, if someone could help me figure out what is causing the crash that’d be great!

Can we see the rest of your code please? I use RMC extensively in my game and haven’t ever had a problem with it.

Break on that line…see what items are invalid.

I would guess that your ‘mesh’ is null.
