[C4D] General Discussion / Re: HDRi map problem

« on: 2018-08-15, 21:02:18 »

By any chance, did the scenes use LightMix? And if so, are you viewing the same pass in the VFB (the Beauty, or the LightMix, depending)? I discovered recently that on render, the VFB was automatically selecting the LightMix and not the Beauty on initial render (presumably because the scene was saved with the LightMix open) - on a related note, then opening a scene that didn't have LightMix had the VFB default to the Direct pass rather than the Beauty.

Thought I'd ask you to check what pass you are viewing / saving from the VFB, just in case it's what you are running into (as, assuming you had the scene set up with the HDRI in a CoronaLight material and not in any other sort of material, there should be no change)

Woohoo! CTRL + drag to copy is nice; would it be possible to have it also copy the connections when used? :)

Currently it copies connections between nodes that are duplicated, so if you select both node and nodes that are connected to it and than CTRL+drag it, it should work... but we should probably add some command/shortcut to select node including its hierarchy to make this easier...

So it does, cool! Also cool is the bounding box select, nice!

On whether it should copy existing connections or not, I guess one for the users to chime in on; I'm just kinda used to it that way from Max, but not to say that it has to be done that way, especially with this functionality of "copy all nodes and connections from what was selected" (as that is something Max doesn't give you an option for, and I can see that being useful where you are already planning on changing some aspects of the new material).

Could you send over a scene you are having problems with? The simpler one would be good :) You can use the private uploader https://corona-renderer.com/upload

Also, in this instance, it would be great to see a video capture of what you are experiencing, so we can see just what you mean by lag, and when it is happening (and we could then share our results with your test scene for comparison).

Well, as a note, just because something is free, doesn't mean there are rights to redistribute it - something you have to check very carefully! So be sure you have the rights to share things before posting them here on this forum too. You can use the private uploader to share a scene for debugging purposes; or you can remove any protected (even if free) assets from the scene and provide a link for users here to go download the asset for themselves and add it back into the scene.

Strip rendering is the first thing that comes to mind. Note that the "farm" in question could just be the one machine :) https://knowledge.autodesk.com/support/3ds-max/learn-explore/caas/CloudHelp/cloudhelp/2017/ENU/3DSMax/files/GUID-0A49D59A-313C-438F-9698-71C1263AD432-htm.html

I think this will be the same issue as "blurry refractions seen in blurry reflections" that has been reported, only multiplied exponentially by lots of small objects doing that. BTW, enabling caustics for that material will raise your rays/s, though I can't speak to what it does to the look of the render.

So, in the meantime, first thing would be to change that material. In the scene the sugar probably doesn't need translucency, and glossy refractions, and subsurface scattering, for such tiny objects. I am sure a good material can be obtained without such a complex material :) Though refraction seems to be the one that impacts performance (didnt do exhaustive testing). I just turned it to 0, but perhaps less glossiness would work, or removing the SSS and translucency might help, etc.

Still leaves the question as to why the same material performs differently with different Corona versions though.

Scene as sent
1.7.4:
Total 648,169
Actual 688,722

2:
Total: 294,493
Actual: 338,589

3:
Total 275, 737
Actual 239, 797


Quick test making refraction 0 for the sugar material

174:
Total 1,098,967
Actual 1,171,046

2:
Total 986,182
Actual 1,059,827

3:
Total 1,015,323
Actual 823,261

(so, even if we resolve what is happening, that is still one heckuva hit to your performance just for the sugar :) )

As a note, the scene as loaded reports some missing texture maps, and has Ornatrix too, which I don't have installed.

So, turning off the Refraction for the sugar scatters speeds up the Corona 2 render a lot. So the issue isn't with Scatter itself.

It seems to be the Corona Scatter in the sugar bowl.

In tests, I found 1.7.4 fastest, 2 was slower, 3 daily was slower again (in terms of rays per second). Hiding the scatters in the sugar bowl caused a massive jump in rays per second in Corona 2. I wonder if related to this report about a scatter slowdown? https://forum.corona-renderer.com/index.php?topic=21394.0

EDIT or it could be the materials on those scatters, haven't looked yet, just noticed that hiding them makes a huge difference to performance.

Is it possible you can share the scene? There's the private uploader https://corona-renderer.com/upload if you can't share it with the whole world here :)

Would be interested to see what those SSS materials are set up like, and the scene would answer that and more. Cheers!

They actually aren't from different angles. The font is just different in the render and the realtime (if you look at the non-font items, they are in the same place - it's just that the extruded font is different so it intersects objects at a different place; in my case, the font was actually entirely different, the letters had a different shape too, as the font wasn't installed but C4D insisted on showing it in the realtime viewport even though I didn't have that font)

Hi Danio, the install is an option in the Corona installer, you'll need to use Custom and enable it :) It's off by default. It should then install all NVIDIA Optix stuff that you need. Be sure drivers are up to date as well.
