Hello. I downloaded few examples of VDB animation sequences from free downloads to test my renderer and all of them could not be loaded using latest OpenVDB 7.1.0. Then I installed latest version of EmberGen beta, exported animation from one of examples with compression checked off and this still cannot be loaded!
The OpenVDB library sends exception when reading metadata “file_delayed_load”. The wrong thing is in the BLOSC processing.
The examples from openvdb.org are all OK - I can read them and render.
Line 179 of DelayedMetadata.cc
compression::bloscDecompress(reinterpret_cast<char*>(mMask.data()), count*sizeof(MaskType), mMask.capacity()*sizeof(MaskType), compressedBuffer.get());
The exception message says: RuntimeError: Expected to decompress 144 bytes, got 18446744073709551611 bytes
