FPP with large proxies create long scene load times
« on: June 12, 2020, 02:15:51 AM »
Hello,

We have been having some issues with FPP and corona proxies where our scenes become very slow to load.

Last night I did quite a bit of testing and found that there seems to be a limit in the amount of polys you can load into a single FPP to keep scene opening reasonable.

As an example - I had an FPP with 23Mil of polys (mesh mode) across 6 corona proxies. That single FPP took over 2 minutes to load. When I instantiated it took 20 seconds to load. When I reduced the amount of proxies equating to approx 6 million polys it took 30 seconds to load.

Are you aware of this and is this to be expected?

Hi
we have done some testing as well and can confirm that corona proxy workflow is a bit slower than using vray proxies or regular mesh.

Scene. 6 trees, 4M each.


Growfx version  / With FP
303s / 350s to load

Just Mesh Version / With FP
8s / 44s to load

Just CoronaProxy / With FP
2s / 72s to load

Just CoronaProxy Version Full Mesh / With FP
32s / 79s to load

Just vrayProxy  / With FP
2s / 2s to load

Just vRayProxy Version Full Mesh / With FP
18s / 64s to load

Just Xref Version / With FP
10s / 47s to load

Delay is caused by reading the mesh of the proxy. It's needed to build the point-cloud and to calculate the proxy size.
V-Ray proxy is much faster because it returns an approximation (the same used for the viewport), not the full mesh.

We will contact corona team to inquire about possible solution.

Hi Rokas,

That makes sense to what we are experiencing.

Thanks for the quick reply. We will instantiate any FPP's with large poly count trees until there is a solution.

Hi Rokas,

Did you get a response from Corona team?

Also have you tried with Sini ProxSi?

We were thinking this could be a workaround in the short term.
