draco_transcoder is the transcoding tool.
The following options are available:
-iinput
input file name
-ooutput
output file name
-qpvalue
quantization bits for the position (default: 11)
-qtvalue
quantization bits for the texture coordinates (default: 10)
-qnvalue
quantization bits for the normal vector (default: 8)
-qcvalue
quantization bits for the color attribute (default: 8)
-qtgvalue
quantization bits for the tangent attribute (default: 8)
-qwvalue
quantization bits for the weight attribute (default: 8)
-qgvalue
quantization bits for any generic attribute (default: 8)
