Worked: (newest version of Blender that worked as expected)

Short description of error

Please test this again with the [release version of 2.91 ]] and the [ https:*builder.blender.org/download/ | current daily build of 2.92 .

If the problem persists, please start Blender from a terminal with the --debug and --debug-gpu flags, redirect the output into a file, repeat the steps to get the pink shader, close Blender and attach the log file to your report.

/Applications/Blender.app/Contents/MacOS/Blender --debug --debug-gpu > ~/blender_debug_output.txt 2>&1

@rjg Same results as before when trying on the "Rosetta" translated version of Blender 2.91 final. I saved the Terminal script for the ARM64 version in a file as asked.
Let me know if there is any thing else I can do to help as I'm positive no one at the BF has a M1 Mac to run test with.

Hope this helps. Terminal Saved Output M1 Mini (Tree Creature)

Tagging @Stefan_Werner just incase he wants to peek at that Terminal file, since he has been the developer heading up the ARM builds

| Error: Implementation limit of 16 active fragment shader samplers (e.g., maximum number of supported image units) exceeded, fragment shader uses 21 samplers

So is that just a limitation in the code, or a hardware limitation?

@CookItOff can you upload your blender_system_info.txt to check if this a hardware limitation?

@EAW no problem.

This appear to be limit set by macOS, see this comment by Brecht and the many other applications that report the same problem.

@CookItOff Could you please try to simplify the material and check if this allows you to render it? If it works, then this is the same issue as discussed in the linked ticket.

Relevant part of the system-info.txt:

****

Maximum DrawElements Vertices:	1048575
Maximum DrawElements Indices:	150000

GLSL:
Maximum Varying Floats:	150000
Maximum Vertex Attributes:	16
Maximum Vertex Uniform Components:	4096
Maximum Fragment Uniform Components:	4096
Maximum Vertex Image Units:	16
Maximum Fragment Image Units:	16
Maximum Pipeline Image Units:	80```

I agree with @rjg, the material in question just looks like it is going over the limit. Easy enough to test @CookItOff, just connect only one of the Principled BSDFs instead of the two that are currently connected.  Or just delete part of the node tree.

@rjg Thanks for the link.
I disconnected one of the node inputs in the "Bark" material and it indeed render as expected, minus of course the previous linked nodes.
Thanks for working with me to diagnose the issue.
I wonder if other DCCs are having this same issue when working with materials on a Mac.

@CookItOff thanks you for checking. Yes, it seems that other software had the same issue, for instance Substance Designer had a long forum post about this as well.
