[C4D] I need help! / Jagged displacement problems
« on: 2019-05-01, 08:47:17 »
I'm trying to deboss some type onto a gloss surface, but I'm getting jagged edges rather than the smooth transition that I'm after.
The image i'm using is 4k, black and white, I've tried 16bit and 8 bit. Rgb and greyscale. Blurring the edges in Photoshop and blurring the edges in the C4D. But the artefacts are still there.

Am I missing something?

[C4D] Bug Reporting / Normal Shader broken. Hotfix 2, V3 C4D
« on: 2019-04-05, 09:48:22 »
I am updating a project i built last year:

In the Bump channel I had a normal map (from Poliigon) inserted via the Corona Normal shader and scaled via the projector shader.
Everything worked fine. But when I have come to update the project and re-build the material it's not working properly.
The normal map looks inverted and the projector is not effecting the scaling.

If I remove the normal texture from the corona normal shader and plug it directly into the bump map via the projector, everything works as normal. So it seems to be a fault with the Corona Normal shader.

See screengrab for clarification. Any idea of a fix? Or is the Corona Normal shader now redundant?

[C4D] General Discussion / Node editor - I'm clueless
« on: 2019-02-19, 10:05:30 »
I've mentioned this before - but I'm resurrecting it.

I want to start using the node editor more. But I can find literally no training or guidelines for its use (Using c4d on mac)
I can't even work out how to add adjustment parameters such as colour correction etc. And stabbing at possible key combinations is getting me nowhere.

Can someone please give me some pointers or links?

It's been mentioned before in the topic here: https://forum.corona-renderer.com/index.php?topic=19517.0
But I've now tested to make sure it's reproducible.

If alterations are done in Corona post processing AFTER the render has finished (in Picture Viewer). When you go to save out the layered PSD file, the background beauty pass is missing.

If you're interested my test file is here: https://we.tl/t-9JP55Ab5Vi
it includes 'test A.psd' which i saved out directly after rendering. Plus 'test B.psd' which i saved out secondly after altering the tone mapping. AS you can see, in 'test B' the background image in missing,

Using the Corona 3 full release, C4D 20, mac, latest version of Ps.

35
I'd like to start using the node editor more - but there's virtually no instructions/tutorials i can find.

In particular id like to know if it's possible to make a 'layered' material in a single node (ie without the supporting 'base' and 'layer 1' materials in the materials palette).

As a side note, now that we're in a final release there really needs to be more help/tutorials on the correct usage of certain features (Keyshot has a good model for this, where they have a regular (monthly?) webinar on a particular feature or workflow). Something to consider? ;)

[C4D] Feature Requests / Missing Texture warning
« on: 2018-12-17, 11:21:00 »
Please god, implement a warning box that pops up when you try and render with missing textures. It's catching me out waay too many times

Hi, I'd set up some files in B1 (mac). When I've gone to make some adjustments to them using the latest build and r20 it renders very differently.
There's a screengrab attached of the same file rendered in r19 B1 and r20 latest build.

It has a coloured pattern in the reflection slot - it seems to be reacting differently perhaps?

As a side note, it would be useful to run different builds of corona simultaneously (ie r19 with B1 for stability, plus r20 running the latest build for testing. Rather than having the installer overwrite all versions).

[C4D] General Discussion / r20 support
« on: 2018-09-04, 11:07:11 »
Hi  - just wondering when C4D r20 will be supported. I guess quite a few people are upgrading this week.

39
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).

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.


42
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

[C4D] General Discussion / Are caustics working?
« 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.

44
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
R
