This repository demonstrates behavior differences between Maya 2019 and Maya IO 2019 when rendering via MtoA (3.2.0.2).When rendering the test scene, Maya IO 2019 appears to crash, but Maya 2019 does not.
The scene consists of:
- a poly sphere
- an
aiFlatshader (color driven viaAiImage.tiff file) - a poly plane
- an
aiAreaLight
git clone https://github.com/AtomicConductor/mayaio-2019-bug-repro.git
cd mayaio-2019-bug-repro
Download/acquire the following software packages:
Autodesk_Maya_2019_Linux_64bit.tgzAutodesk_MayaIO_2019_Linux_64bit.runMtoA-3.2.0.2-linux-2019.run
Place these three files within the installers directory (replacing their corresponding placeholders):
installers/Autodesk_Maya_2019_Linux_64bit.tgz
installers/Autodesk_MayaIO_2019_Linux_64bit.run
installers/MtoA-3.2.0.2-linux-2019.run
Execute build_n_run_tests.sh, and provide your Autodesk license server as an argument, e.g.
./build_n_run_tests.sh '42.052.12.200'
After the script completes (5-10 mins), the shell output will contain the logs from the successful render execution (Maya 2019), as well as the crashed render execution (Maya IO 2019).
The build_n_run_tests.sh script does the following:
- base image (from centos 7.5), including an installation of MtoA 3.2.0.2.
- Maya 2019 image (layered upon base image)
- Maya IO 2019 image (layered upon base image)
-
Runs the render test using the Maya 2019 container
Render -s 1 -e 1 -rd /tmp/output -proj /tmp/content /tmp/content/maya2019-mtoa3.2.0.1-basic_01.ma -
Runs the same test using Maya IO 2019 container
Render -s 1 -e 1 -rd /tmp/output -proj /tmp/content /tmp/content/maya2019-mtoa3.2.0.1-basic_01.ma
Each stage of the process can be re/run individually as desired. See the contents of build_n_run_tests.sh.
For example, to re-run the maya io render test, simply call:
tests/mayaio-2019/run_test.sh
Maya 2019 renders successfully without crashing (despite the noted errors/warnings).

I was able to prevent crashing in Maya IO 2019 if I refrained from using a texture file in my geometry's assigned material, i.e. MtoA would render successfully if the default lambert material was used.
