Newer Arnold version corrupt textures converting into TX

For me after Arnold version 3.1.1. newer Arnold version and last 3.2.1 converting tx files really differently, corrupting them. Textures where created and exported by Substance painter.
In uploaded screenshots it shows the difference uncoverted and coverted tx files. In older Arnold versions starting from 3.1.1 coverting goes fine. I dont know why the results are so different and how to fix that?

Hello Stephen, did you check my .tx file that I uploaded? Is it working fine for you too? Anyway thank you for testing, so the problem is on my end. What can cause that? I tried to reinstall MtoA several times, probably should restart after each reinstall, probably saves some temp files in registry. Strange that it is happening to me on new versions both on 2018 and 2019 versions. Maybe some driver conflict?

I started with one of the sbar files that ships with Maya, exported the textures to file, and they all worked fine, both in the older and newer versions of MtoA.

I don't see any problem. There's no diff between rendering with the tx files and the tga files. What am I supposed to see?

Hello Stephen, are you using Arnold 3.2.1 or higher?

In archive that you have downloaded, there are screenshots I made, for example text_tx_png_height_map, where the center part of the wall is tx file from PNG, all other objects have tx. from TGA.

Look at text_tx_tga_height_map and compare with test_tx_png_height_map, you should see the difference, that I am facing.

I'm using 3.2.1.1 and the scene doesn't use any texture files with "height" in the filename.

If the problem is with tga files, can you upload one of the tga files? I don't need anything else.
The Google drive download had jpgs only.

Hello Ashley, updated 2019.1 and Arnold to 3.2.1.1. Nope, coverted wall normally, but everything else is rendering old as hell, all tx files were deleted and reconverted. Problem with tga coverting from Substance Painter is still there.
Anyway I will use PNG then, or use Arnold 3.1.1., I hope my info will help you to make Maya and Arnold better.

Update, I ran more tests, because I am really curious up in it. And it seems that problems starts when it tries to convert height map that is in .tga format to .tx. The funny thing is that it do not happen on older Arnold versions starts from 3.1.1. I dont know why.
I tried to use TIFF and PNG for central wall, and these formats worked fine. Only TIFF basecolour node must be in RAW not RGB.
I uploading scene, fbx file with materials and tests screenshots, with substance to arnold official manual screenshot.

I hope this will help.
