TAV 4.2.1 can run on IRIX 6.5.22 with some modifications in TAV launch scripts and launch command, including Advanced Visualizer Model. At least on my Indigo2 R4400 250Mhz with GU1-Extreme graphic card.
I also play around with Kinemation and Dynamation (interesting early particle simulation software) examples files and found no issue so far.
For Advanced Visualizer Model, Preview, Image, Render, Display and Property, I have setup simple scene (adding 1 model exported from Blender 2.49b without texture and edit the model with Model program to use colors.mtl files, then edit .obj saved in TAV's project directory to use one of colors from material file) and I was successfully render an image.
Be minded tho, if the model imported is high/very high poly model even if the model fit with in memory of your SGI or improper .obj format that TAV didn't support, it may crash Model or Preview program.
Also, if you have Alias|Wavefront Explore Professional newer than v4.2.1 installed and it doesn't have render program in /usr/aw/EXP4.3.x/bin, TAV Render will not work (missing render program error), to fix it you have to uninstall the newer version and use v4.2.1.
I also try to run TAV 4.2.1 on my Tezro with V12 graphic card, only Advanced Visualizer Model and PreView seems to have problem with corrupted graphic in viewport (unusable) but all other programs seems to work tho.
I didn't try to do any serious rendering with TAV yet, other than some quick experiment, due to few relevant documentation or tutorial of this software exist online :<
If you have TAV manual or training VHS, please consider scan/digitize it and upload it to archive.org.
There are some video demoing TAV usage on the net tho, I'll list the video link below
Wavefront Pictureout - SGI Demo
at around 8:25 is demoing the usage of TAV to create presentation animation of a piston assembly.
including the usage of Model, Property, Preview, Image/Render?, Paint and Composer.
Wavefront Gamewave Cyberworld 199x
This video demoing the usage of TAV for game creation.
including the usage of 3Design, Model, Kinemation, Dynamation and Composer.
Wavefront Gamewave Cyberworld 199x MKV
Wavefront Movie 1986
contain video screen of early version of Wavefront (later known as The Advanced Visualizer) running on SGI IRIS 2000 Series
The lastest release of TAV is version 4.3.2 according to qualified hardware list on old Alias|Wavefront website
I can't find qualified hardware list of older version anywhere on the internet tho.
This is how I get it to work on my Indigo2 with IRIX 6.5.22, I don't remember what I have edited, other than /usr/aw/COM/setup/auto_env that i'm pretty sure it haven't been modified (or not) so I'm typing the content of almost every startup scripts of TAV on my Indigo2 below.
In ~/.cshrc in my profile
In ~/.aw_custom_env in my profile
# Check to see if IPR/Render is installed
#which ipr >& /dev/null
#if ($status) then
# setenv AW_PROD_ENV tav
setenv AW_PROD_ENV tavipr

if (-f ~/.aw_custom_env) source ~/.aw_custom_env
may not need, but I'm not sure.
setenv LD_LIBRARY_PATH /usr/aw/COM/lib
and finally, a script to launch TAV Director. Copied from launch command used in TAV toolchest. I named this script run_tav and saved it in my profile directory, then dragged it to desktop.
You must run TAV from this script, else Model and PreView will hang at startup.
/usr/sbin/xwsh -geometry 80x24+529+680 -iconic -title Director -icontitle Director -e $WF_AV_DIR/bin/director
