I dont know what is this call

I always getting this error message everytime i turn on 3ds max, i have all folder and admin permission, no block, permission is full control.

That’s a 3ds Max message, and as far as I know, 3ds Max can’t read .tx natively (without Arnold/V-Ray), so you can ignore it (disable open on error).

I am using V-Ray but cannot read also?

I did not understand what you’re saying. Are you getting errors with .tx files or what?

you mention this, so I ask I have V-Ray installed with 3ds max, why still cannot read .tx file?

V-Ray can read .tx files, but 3ds Max can’t (native Bitmaps). The error is strictly from 3ds Max.

Thank you for your explanation
