Re: [Opensg-users] How to set shader parameter to vec3 array?

The working code looks like this: MFVec3f parameters = MFVec3f(); <- without specifying the field size!!! Ah! Sorry we missed that one. Yes, passing in the size will set the actual size to 3, not just reserve 3 elements. So your push_backs were put into elements 3, 4 and 5, and you got uninitialized data into the shader in 0, 1 and 2. That's new to me, too. Thanks for the explanation! Thanks to Daniel for the hint! Always happy to help. ;) Daniel
