Line MAT doesn't Render

I am trying to simply render a circle with Line Mat but it basically goes dark and it doesn’t show anything. I have a MacBook Pro 2014, 2.2 GHz Intel Core i7, Intel Iris Pro 1536 MB.
Touch Designer version 2019.3703030 Jan,
Please help!

Line MAT.toe (3.8 KB)

I use macOS High Sierra version 10.13.6

Hmm. Opening your file on my 10.14.5 Mac Pro, this seems to render just fine for me. It looks like you’re doing it right. Anybody have other ideas?

There are some reported issues with macOS Intel GPUs affecting the Line MAT. Can you post a screenshot of your ‘About the Mac’ so we can see the full GPU specs?

Thanks Ben,

Oh, I was expecting a model number but they just call it ‘Iris Pro’ :confused:

This is what I can read from system report

I posted a tutorial for the Line MAT recently and had quite a few people comment who were having this same issue on Mac.

This is what I got form people when I asked for specifics:
“2014 MBP with the most current version of TD (2020.20625) in the Catalina OS.”
“2015 MBP i7, 1536mb iris intel graphics card, TD build 2020.20625.” (they didn’t include OS)
“mid-2012 Mac, MacOS Catalina, TD build 2020.20625.”

I didn’t think to ask for model number, though I could follow up to get more info if it would be useful in troubleshooting this!

Hi @polyhop, yes this is a known issue. Unfortunately the Line MAT is a very complex shader using geometry shaders and bunch of advanced things under the hood and it is proving to be quite unreliable on macOS with Intel GPUs. We haven’t been able to reproduce on the supply of Macs we have in the office yet, we only have 1 with an Intel GPU at this time. Wish I had better news.

Hi @ben , Hope you are well and safe. I’m having the same issue, it is there some news about this? Thank you for your time.Screen Shot 2020-06-08 at 19.57.17

Also having this issue. Sent a crash report yesterday in relation to this.

Funny thing is, Wireframe MAT works, so exploring that instead.

Just so we can build a list of GPUs that are problematic (and perhaps try it on the same one should we have it), could you include a screenshot of your “About this Mac”?

Sure:
