i am using the SDK_2016_R2 examples to try and figure out the new framework changes. I have run through all of the examples for ios and all of them work except the oglesskinning. i am trying to understand the new pfx format and we also are using bones in most of our models that we use on our 3.2 version of the software. here is the warnings and errors that i get.

it’s crashing in createDescriptorSetsAndBuffers.
if anyone has any ideas i would love to hear them.

Hello again Joel,
Which version of iOS are you trying to run the example on?

The bug you mention has been fixed after the release.
The github repository contains the fix. You can find it at
More specifically, changes are located in the following file: Framework/PVRApi/RenderManager.cpp
line 939: assertion(pipedef.descSetIsMultibuffered[setid] || materialpipeline.sets[setid].size() == 1);
