Author Topic: 2.1.1 change in bit depth on export  (Read 1541 times)

Did something change in the control of the bit depth of textures on import between versions 2.1.0 and 2.1.1?  It appears that in 2.1.1 when 16-bits is specified, all channels are exported as 16-bits even if there is only 8-bit data (e.g. base color RGB).  2.1.0, on the other hand, seemed to export 16-bits only if the channel was high dynamic range (e.g. height map or normal).

I prefer the previous behavior for economizing memory.

The bit depth is now forced to the value specified in the export window. This means 8bit channel can be exported as 16bits indeed.
We did that to avoid confusions, because we got a lot of support on that matter.
Don't forget your log file. It can be exported from the Help menu of the software.

Thank you for confirming.

For me, per-channel control would be better.  Now I have to export 8 and 16-bit maps in two steps or convert them in Photoshop.
