bug: Error Running ODM with stacked multispectral images #1979
Description
When reconstructing a multi-channel input from a MicaSense RedEdge-P camera, I get the following error creating the texture:
Image must be RGB or RGBA
Eventually, it is possible to skip this step or remove the additional channels for the creation of the texture.
Otherwise this upstream issue discusses if the fix should be placed in this repo or in the texrecon tool:
simonfuhrmann/mve#584
