Apple imac M1 chip

[b_berning]

Hi,

I've recently bought an Imac with M1 chip and thought this a good time to try and use Vray for Sketchup. However, it takes forever to make even a simple rendering (at least I think it's a simple rendering). What am I doing wrong, or is this normal? What is an average amount of time for a 1200x900 pixel rendering? I'm using the CPU engine as this seems to be the fastest (CUDA or RTX are the other options, but appear to be slower). FYI: I have hardly any knowledge of the inner workings of computers, CPU's, GPU's etc. Nevertheless untill now I always managed just fine... Hope someone can help me.

Thanks

You are limited to CPU rendering on M1 machines, running GPU code won’t help at all. Even though is a very good one the M1 is still an entry level SoC so you should have realistic expectation about the performance. Also Vray it is not running natively right now, but this will be probably solved in the coming weeks.
There’s no such thing as an average amount of time for an image, it all depends on the scene complexity and it can take from seconds to several hours regardless of your hardware.
If you show a sample image with the render time it will be easier to understand if ther’s something wrong.

Thanks Sirio76, It might very well have to do with lowering my expectations, I'm likely influenced by all these nice tutorials that render in seconds, but who knows what kind of computer is behind that, probably not my 'commercial Imac with M1 chip'. But just to be sure: I've uploaded a screenshot of the rendering process. It doesn't give the rendering time though (or I didn't find it). Yesterday this frame took about 1,5 - 2 hours to render. The sketchup model that's behind it is 3.7MB and as you can see, no complicated details or anything.

There is definitely something wrong there, here is a report from a M1 user and he is reporting barely 5minutes for a more complex scene rendered at higher resolution:

Even in emulation that scene should take a couple minute on an M1, it’s unlikely to be an hardware issue, probably a wrong scene setup or unknown software issues.

That's what I thought. What would be the best way to solve this? Uninstall and install Vray to begin with? Or reset to default?

[sirio76]

Reinstalling the software maybe a good idea, then ask developers or some forum user to check if there’s something wrong in your scene setup (I would be happy to check you scene but unfortunately I work with Vray for Cinema4D).
Then wait for the native M1 version, is coming very soon.

I will have a go at reinstalling. If I still have problems, I'll see if some other forum member can help me. For now, thanks a lot for your help!

Hey b_berning

The current builds of V-Ray for Sketchup doesn't support M1 natively, a new update with ARM support comes out soon with better rendering performance.
If reinstalling helps let me know as well, the test you posted above is slower than expected indeed.

Best,
Muhammed
