[C4D] General Discussion / Re: Stacking with Displacement....?

« on: 2018-06-28, 22:52:33 »

There is a problem with displacement and material stacking in corona at the minute.
But in your case could you not solve the tiling problem by using Set Selection to make a poly selection of the area where you want to apply the label - then only apply the displaced material to that part?

I don't see a problem with replicating this scene. Helpfully, you can see the lighting setup reflected in the bubbles.

If you need to keep an area artificially bright (like the back wall) try adding self illumination into the material  - but turn off seen by gi in the editor slot so it doesn't start to light the scene.

[C4D] Resolved Bugs / Displacement: stacking causes massive mapping error

« on: 2018-04-29, 14:59:24 »

Mac OSX 10.13. Error occurs in Corona B1 and latest B2.
I'm trying to make a stacked material. The 'bottom' material has displacement and the 'top' had the main material.

If the displaced material is on top, it is mapped correctly (using flat projection, no tiling, front only). As soon as you move it to the bottom (which is necessary for the displacement to work in the hierarchy), the mapping jumps to a totally different place.

Hopefully the screengrab illustrates this better than my wording!

[C4D] General Discussion / Quickly output to layered sRGB?

« on: 2018-03-23, 09:37:37 »

Hi!
Normally its fine to output my renders with multi-passes to 32bit linear. But frequently when I'm doing look-dev & testing work, it would be easier to output directly to 8bit sRGB (or indeed 16bit aRGB) psd's.

Is it possible to do this from the pictureviewer?

Whenever i try, it defaults to linear colourspace which is not good for what I want (the multi-pass layers are just simple object buffer masks).

I presume it work if you used render region instead of camera tiling?

[C4D] General Discussion / Re: Will render farms adopt Beta1 now?

« on: 2018-01-08, 13:11:54 »

I signed up at www.ranchcomputing.com last week. They say they now support Corona Beta 1 RC 1.
(I haven't tried it yet though)

If you have an Adobe subscription you can use their portfolio app (it was previously the behance pro portfolio). Its simple to use , looks good, and can easily be password protected.

[C4D] Resolved Bugs / Inconsistency between rendered image and picture viewer

« on: 2017-12-06, 19:51:14 »

Hi, I posted about this in the general thread, https://forum.corona-renderer.com/index.php?topic=18491.0 but it's worth repeating here:

There is disparity between the Cinema4d picture viewer and final render, where the final rendered image is more 'washed-out' in all formats/bitdepths.

Yep the other renderers are fine. Will post a note in the bugs section too.
Thanks

Oh dear... I though it may end up like this ;) Thanks for the reply.

It's still a problem which I think needs solving though. The disparity between the Cinema4d picture viewer and final render especially.

Here's some general information in case its useful:
My work is always stills - for web and print output. And Photoshop is used for all post/processing.
While I sometimes keep an aRGB 16bit master, the delivery format is almost always 8bit sRGB.
From Corona saving out all formats and bit depths result in the more muted colours. (See attached)
Photoshop is better than it used to be at opening exr files - but it won't be able to see the contained passes - so really I need to save out layered psd of tif.
My monitor is calibrated with a Spyder

I just think there must be a more reliable way of matching outputs - even if it involves an extra conversion after opening in PS.

Interesting video BTW. Although oddly I found the 'filmic' outputs looked less 'real' than the old versions.

[C4D] General Discussion / Washed out images - help me understand!!

« on: 2017-12-05, 14:16:53 »

Hi - I have an ongoing problem where my images are looking washed-out compared to the C4D picture viewer. (And crucially, my expectations). I had initially thought that this may be a gamma issue when using linear colour space. But I haven't found a solution to output the images 'correctly'.

There's a screengrab attached of what I mean - any ideas??

Cheers

« on: 2017-10-05, 16:27:05 »

Is this implemented yet? I'm trying in the latest build but it's not working.
The Caustic box is ticked in refraction but the shadow looks solid. have tried adjusting various light types and IOR values but no success.

[C4D] General Discussion / Exposure best practice: Sun or post?

« on: 2017-10-01, 16:06:57 »

Hi, I'm pretty new to this and would like to use the most commonly accepted method.

If i'm lighting scene with a corona sky and sun it is extremely bright by default.

Is it best do adjust the intensity directly and leave Exposure at the deafult of 0. Or it it best to leave the sun/sky intensity at 1 and compensate by adjusting the exposure in the VFB settings?

Cheers
