We have a setup for the vive and twinmotion on a fast Window machine at our ATC which is half the cost of a iMac pro and includes the Vive, SketchUp Pro license and twinmotion license…
Yeah I have a Vive on my PC here at home. I have been looking at an Enscape license but I will look into Twinmotion now too! Especially as it’s running on UE4.
You might want to create a Steam account and play with:

(Still in beta, do not know pricing)
It’s free, I have had it for a while now, since last summer. It can load up surprisingly large models.
Yeah Twinmotion is a bit too pricey for hobby work, maybe they will have it in my new office or let me buy it.

Ars review is out: iMac Pro review: Working as intended | Ars Technica
I am getting 8 and 10 core version in about three weeks for a tests so will make some benchmark and check how it really works for me
Yes it will be interesting to see how far you can push it. I wonder how long until they release an official external GPU adaptor.
I am downloading trial version. I will share some sample images soon

I am not going to tease myself by even trying it out haha
Yesterday I installed Twinmotion. At first sight this software is not so user friendly as other (which I tested). After first run, I got suggestion to watch video tutorials on their YouTube channel. But there is no tutorials for new Twinmotion (new version has significant changes in interface). Than I tried to import my old model and make some test views. I encountered a problem with a mirrored geometry, doors and chairs are looking different with same material. Second problem was with the glass, the rays did not want to pass through the glass roof (but I think it should be solvable).

I have a base model iMac Pro and have been playing around with a trial version of Vray 3.6. Admittedly I’m not blown away by the iMac, but I’m also not too familiar with Vray and its settings. I’ve also dealt with quite a few crashes (hanging or crashing), but that’s a different topic.
For rendering options I have CPU and GPU (w/C++), but I’d love to hear thoughts on various settings I should/can play around with. I honestly don’t know the disadvantage of the GPU w/CPU option over the pure GPU option in terms of render times.
My results on the Vray benchmark were right around the minute mark.
Aside from Vray, SketchUP itself doesn’t seem to benefit as much from the iMac Pro as much as I’d expected either. I’ve been using SU for 15+ years and think it’s great for what it is, but feel the way that it handles materials is especially ridiculous. For example, clicking on a material to edit it takes a full few seconds to open. It doesn’t sound like much, but over the course of a home model, it adds up. I’m careful to use components, minimize the number of materials (usually ~30 per model) and keep the geometries clean, so I assume it’s simply the way the SU for Mac is built. Any thoughts on this would be appreciated too.
I just bought the iMac Pro basic model today and I’m very disappointed by the performance. After reading the comments here I did some further research - the most significant comparison I found was this one:
At the moment thinking of exchanging it to a top spec iMac.
What are you using it for in general besides SketchUp?
Unfortunately vray does not support AMD cards and Opencl for gpu rendering. Only NVIDIA cards and CUDA. Your rendering will be entirely CPU bound I’m afraid, VRAY is massively faster with GPU/hybrid rendering.
For rendering, the iMac with the i7-7700K will be much slower, as it has 8 logical cores (4 physical) while the Xeon has 16 logical(8 physical) cores. In single core performance (the one significant for Sketchup modelling) the i7 has an infinitesimally slight advantage, nothing you would probably notice. Image from PassMark:
So if you want to use a Mac, the iMac Pro is the most powerful you can have.
I’m using SketchUp mainly for design purpose hardly do any renderings. What I was thinking is to buy the following configuration instead of the iMac Pro:
4.2GHz quad-core 7th-generation Intel Core i7 processor, Turbo Boost up to 4.5GHz
64GB 2400MHz DDR4
1TB SSD
Radeon Pro 580 with 8GB video memory
I thought about this purchase in the first place but decided to buy the iMac Pro due to the similar price.
