the shaders are called capsfreebies and they load into the browser using the load folder option yet when i open the folder in the carrara folder then nothing is listed where the samples are shown. 

It also came with a model of a home and it states its not a valid carrara file when i try to move the model to the scene. 

 

I have an older version, carrara5 , would shaders compiled by newer versions not be compatible with older versions?   The shaders in caps freebies have the  *.cbr extension.
