[C4D] Bug Reporting / Re: Displacement problem
« on: 2022-05-20, 01:34:13 »
Displacement is a problem in Corona render. I have images with gravel for pavement and you always see fine straight lines every where. I also see it in images posted in the galleries. In Corona render its best to stay away from displacement for architectural work. But without displacement the photoreal image quality suffers a lot.

But displacement for masonry, gravel etc works better at very high resolution rendered images with pixel settings at 1. I am not sure if you can set a finer pixel setting like 0.5. But no matter what you do you get all sorts of artefacts that I think where no problem a while back. The displacement textures for masonry are usually rather bad as well. I think things look better if you have high res displacements maps as well with not all that harsh gradients between what needs to be displaced and what not.

I attached an example of the struggle. This was rendered at high res but the masonry still has artefacts. The same displacement texture and model in Lumion is completely hassle free.

The pavement btw is by the Corona material library and show less artefacts.

Tx Philw
I am not familiar with blender, cycles or the render speed.
From what I saw is that is takes quit a bit more hassle to go from Vectorworks to Blender compared to C4D. That's why I have not bothered with Blender so far.

I got a lengthy support session by Chaos to solve the problem of the cosmos browser not functioning on the Ultra .They got it solved for now by installing the previous version of the cosmos browser.

This is one of the first renders I made with the Ultra 128Gb. I had a terrain modeled that was quit a bit larger taking 125Gb ram at rendering. I reduced the size of the terrain and underneath the house and from then on around 65Gb was in use at rendering. I don't know how long it took to the final render at around 500 samples but it looked not all that different at about 3 min at 12 samples.

I think I spend far more time getting the materials, the model and assets right compared to the rendering proces. Modelling and materialising the scene is completely fluent on the Ultra. (The car is a electric Bollinger that never came in full production).

Ok, that's good news.
I would love to keep working with Apple but not up to the point that my work suffers.

I will check out Blender as well. Do you have a link of what you saw ?

Ok, Tx. Will surely try it again then. But I have a co-worker here beside working in Twin Motion but the work I see done uses the path tracer. And that as far as I know does work on a Mac.

I heard co-workers say it doesn't run well. Crashing and so on.
Enscape is coming to Mac I understand.

Today I had clients over and I really need tools to give them a bit of a look and feel with a real time app. C4D / CR is better suited for fine tuned images. The UI of C4D / CR is also not really for a client / architect meeting.

Hi, I posted a thread about this problem, in my case the displacement mapping and color maps did not match. Anyhow, I also see the displacement problems you mentioned.

I just did an apartment building of over 25 stories in brick (masonry) in CRv9. The geometry was a mess and so got lots of displacement problems like the triangles you showed.

I finally gave up and rendered the project "as is" at a high res of about 3600x4200 and the displacement setting 1 pixel. Results where not as bad as what I saw at lower resolution.

The models I work with are mostly done Vectorworks. When I do them myself I can model the same building at about 20% in terms of Mb's and a lot cleaner to work with a lot less artefacts in the displacements. I am surprised to see though that the messy models of my co-workers do perfectly well in Lumion.

The current displacement problems almost exclude CR for archviz.

Its running Rosetta. Can't change that. So most likely the m1 get too about 50 sec. natively but who knows. I do see that a co-workers PC with a AMD 16 core finishes at about 50 sec.

The m1 Ultra is not super fast but ok. I do think its faster for general workloads aside rendering like modelling, texturing, the asset browser for instant is completely instant if you have your databases on the Ultra's ssd.

The biggest issue for me is wondering about the Mac in general is that my co-workers have great fun with apps like Twin Motion, Unreal, Lumion and a few others that for me or unavailable. I am certain that the main workflow at the office will go through these apps rather than through me with C4D and CR. Looking a few years ahead it might be better to switch now to PC. Actually I had already expected to be far behind but the image quality is still lacking enough to give me an edge over what my colleagues are producing.

use camera clipping.
The area's you mention are indeed very big.  I have 128Gb ram and am still careful not to overload models with large areas of scattered assets.

For grass you need assets of simple geometry or make the area's smaller.

Tx, I am having a session with support to fix this next Tuesday. My Intel Mac is just perfect always and the Studio Ultra beside it never connects to Cosmos for more then a one download at 70%. Very frustrating. My Macbook m1 has no problem with Cosmos either but then I only use it later in the evening. But I did notice downloading the daily builds is slow and it looks like Chaos has a server problem.

I must say that it feels a little unprofessional. Usually Coronarender was rock solid.

don't use per square. It will create far more instances than necessary.

One other thing is I can't get de Cosmos browser to work on my Mac Studio Ultra. Corona support is trying to help out but so far no luck. The Cosmos brwoser downloaded one asset but at 77% stalled. Then at reopening the Cosmos browser I get a white window without assets.

TX, good to know its not at your side. Will check my side then.

Re-installed but still just a white window. My Intel iMac does fine but the new Mac Ultra on the same wired network does not. It did work though but for some reason stopped. Its funny how quick I depend on the Cosmos browser. Especially the 3D people did well in my renders.

I requested support on this issue and hope with some assistence the Cosmos browser gets back.

Benchmarked my iMac late 2015 i7 4 core 32Gb. About 3.11 minutes.

I submitted the result under frv. But can't find it there since there is no search based on name of the poster.

Anyhow, my new Mac Studio Ultra with 128gB is about 3x as fast with the benchmark (Rosetta). Considering Rosetta the Ultra most like is about 4 to 5x times as fast.

Hi, Is it me or is there something wrong at Chaos - Google drive. Trying to download the daily build. Half way but already minutes have past.
Internet otherwise on my system is good.
