PVRTexToolCLI -i E:\bin\res\view\atlas\public\buff_icon.png -f ASTC_6X6 -q astcveryfast -p -o E:\bin\res\view\atlas\public\buff_icon.ktx

What am I doing wrong with the following commands?

Hi simonastcask,

Thanks for your message, and welcome to the PVR Developer Forum!

I tried your PVRTexToolCLI command with a screenshot I took from my screen and it worked fine
PVRTexToolCLI -i sample.png -f ASTC_6X6 -q astcveryfast -p -o sample.ktx

Please check the path to the file you want to convert buff_icon.png and also try updating to the latest version of PVRTexTool from our Developer Portal (please note that you need to create a new account in order to access the Downloads section).

Let us know if there are any issues after those steps.

Best regards,
Alejandro

I have the same error when I compress a texture (640*662) using ver2020R2.

However it works fine in ver1.6.

Maybe the reason is ASTC encoding has been built in texlib since 2020R2?

Hi ShengyuDu,

Thank you for your post and welcome to the PVR developer forum!

After discussing with the Tools Team, they have informed me that there is a fix for this issue.

We can provide you with an internal version of PVRTexTool with the issue fixed. You just need to request it through our support portal (https://pvrsupport.imgtec.com/). Also please specify the Operating System you’re using.

Kind regards,

Stephen
