When trying to understand the impact on memory of my textures, I was trying to use the Statistics window, but even though I’m rendering materials that use certain substance textures, those are not being shown there:
By using memreport -full I can see the textures listed, but their memory usage is 0 (and the format is marked as unknown, even if the texture editor it shows the correct R8G8B8A8 format):
Listing all textures.

The only way I can get some sort of measurement is through obj list Class=SubstanceTexture2D:
Obj List: Class=SubstanceTexture2D

Now my question is: why don’t they appear in statistics? Are the number I’m getting with obj list reliable?
