This is driving me nuts, despite building a much faster system it still crashes repeatedly.
From the start of using version 7 (demo) this has been a PITA. As the model I was building became more complex my trusty old laptop literally ground to a halt, so much for Rhino working on an average computer. So I now have 4gb of video ram and almost 40 gb of internal ram and still it’s dragging it’s heels.
On my old laptop I was able to render a 3200x2400 legacy render using only a directional light in about 5 mins and get a reasonable result.
But on the new system I can still do legacy renders, but the whole point of the upgrade was to be able
to use the new Rhino renderer and get reasonable render times.
But it seems to take ages even before it starts to render, some times over 10 mins of the processor using 30 %, nothing on the GPU, then eventually it starts plodding though the samples.
I gave up on the models I was building (originally started on Rhino5)and started new ones to see if it made any difference. The new low memory models seem to render fine, time wise at least.
So here are 3 renders of the same file to compare.
Legacy, time 10.55 , plus another 8 mins before actually doing anything!
Rhinorender, time 11.20, 214 samples. WTF?
Prorender, time 11.30, 136 samples.
No idea why the Rhinorender failed so badly. The legacy looks poor. But the Prorender looks much better.
So I have continued with the Prorender but it only works on models under 200mb. As soon as I try one of the main models over 500mb it either locks up or totally crashes . Some days it’s crashed more than 10 times!
What makes it even more frustrating is the little models are coming out really well but the models I really need to finish fail repeatedly.
Prorender, 6.5 hours, 1500 samples.
Honestly, I feel like I waste 60% of my precious time with constant stream of failed fillets, failed booleans and failed renders. Just to give you some idea of the competition, this is what’s possible with the latest Z-brush. Am I wasting my time with Rhino?
All modeled in Z-brush and rendered with Redshift(that comes bundled free with a one year sub).
