Lama Parameter Name Changes

Some parameters on Lama nodes were changed in RenderMan 25. The parameters "color" and "normal" have been changed to be node-specific. For example, color is now diffuseColor on the LamaDiffuse node. This was done in preparation for making the nodes compatible with XPU in the future. For scenes with version of RfH older than 25, you need to run once manually top menu "RenderMan" > "Update Lama Nodes" if using a Houdini version older than H19.5.501 (it's automated otherwise). You will also need to update your custom locked HDAs manually.
