Again Missing Mental Ray DLLs

"At present Forest Pack is compiled against the MR libraries so you may encounter issues - but it's hard to predict what actions will trigger them so we recommend Mental Ray is always installed to use Forest. Depending on the status of Mental Ray in new versions of Max , this may change for future releases."

For most users Mental Ray is history. As I use VRay and have a lot of HQPlants there are always those messages regarding Mental Ray. The other day I removed also the "NVIDIA metal ray and IRay feature plugings for 3ds Max 2019" according to a hint of the Autodesk Support because I had another error with network rendering. After that some more messages regarding Menta Ray were showed. After I found that the errors was in my old scenes I reinstalled the "NVIDIA mental ray  ... plugins" again and some of the messages were gone again. Now I only have the messages when loading HQPlants. So my quesion is: Are there any changes regarding Mental Ray with the new ForrestPack 6.1.5.?

Hi, Mental Ray was abandoned by Nvidia some time ago, therefore we don't support it anymore.
Forest includes Mental Ray shaders only for Max 2017 and before, and there are not changes in the latest FP release.

Old HQPlants libraries require it because the V-Ray and Mental Ray materials are embedded in the Max scenes, instead to be separated in .mat files.
