PVRTexTool 'range' setting is not working correctly for signed textures

I am using PVRTexTool 5.5.0 (SDK build 23.2@f6744647926b).

When viewing an EAC RG11 SNorm Linear texture the default limits are -32768 and 32767.
If I set the view range to -1000 and 1000 color component with value -864 is very dark as expected, but
value -1089 is very high intensity (it should be black).


Welcome to PowerVR Developer Forum!
This looks like a bug. Would you mind send an email to devtech.portal@imgtec.com while attaching the reference texture that results into this behaviour. We shall take a look into this.
And is this issue reproducible with older versions? Maybe that’s something you could check and use meanwhile. Previous releases can be found here.

Best Regards,


Thanks for the quick answer. I have sent an email with the reference texture.
I have tried 5.2.0 and it has the same issue.
I have 4.22 installed, but it seems to me that it doesn’t have this (very useful) range feature.

Best regards,
