I am using a pose morph with a target rig in this file, but the IR does not refresh when I move the pose slider.

When you are working with materials that require "huge" displacement values, the preview rather quickly becomes "unreadable" or black while the preview rendering starts to take up very long times.

Now Ales Krivak from Chaos Czech reminded me I can increase the scale of the preview "ball" (or whatever) to always get a proper preview, but I don't think that people usually go there and make changes (nice workaround, though).

My suggestion is capping the values to a certain fraction of the preview scale. Usually the preview sphere has a size of 36 cm, the other shapes are around the same size. So the capping could be 15% to 20% for min/max here.

You cannot save the value of a Simple Exposure in the Corona camera tag as a preset.
It was working in the Version 9 daily from May 10, it is broken in the Version 9 daily from May 23.

I am not sure it was reported before, so here I go:
When I use IR in the VFB and change the white balance, I trigger a refresh. The other "tone mapping controls" don't.

[C4D] Bug Reporting / Variation shader renders wrong bump
« on: 2022-05-25, 20:07:06 »
C4D S26.014 and Corona V9 (daily time stamp May 10) on Win 10:

When you render the attached scene, the bump from the variation shader renders out of place.
When you plug the Variation into Displacement instead of bump, it renders where it should.

When I re-watched the Version 8 webinar, I remembered a suggestion I already made in "Daily Builds". In the Curvature shader presentation it pretty much boilt down to "and this shader is used as a mask for ...".

So here's my request again: Add two outports that provide us with a mask for concave and one for convex. It saves us from having to change the colors to black and white. Keep the original output, of course, it is useful in some cases. But the masks are needed a lot more often.

When I switch on displacement, I get artifacts along the shadow terminator, even far away from the actual displacement.
The artifacts aren't there without displacement, even at the same polygon density.

[C4D] Feature Requests / Some ideas for Chaos Scatter
« on: 2022-04-26, 21:09:58 »

Here are some suggestion for the Chaos Scatter tool:
- An option to influence which clones are being created where depending on a grayscale map.
https://forum.corona-renderer.com/index.php?action=dlattach;topic=36146.0;attach=164192;image

- You can set a "frequency" for the clones in "object / instanced children". It would be nice if the setup field worked like a standard C4D input field and we could also easily reset the value to 1.

- Would it be possible to visualise the camera clipping distance somehow?

- Surface Scattering: Add a min/max height to make it possible to limit the growth - think water level of a lake or growth limit on a mountain.

[C4D] Daily Builds / New Tone Mapping
« on: 2022-04-06, 21:37:53 »
The sorting by category is nice, but not done tidily. It rather looks like accidental indentation than subheadings.

The single ACES parameter is fine for now, much clearer in what it does than the multi parameter one we had before.

[C4D] Bug Reporting / Corona Crash when rendering to PV
« on: 2022-03-23, 23:30:50 »
Corona V8 RC 2, R25.117, Windows 10
Crashes reproducibly in "Preparing geometry 4/21"

Scene and bug stuff uploaded.

PS
It looks like disabling Motion Blur helps (well, it does not help, it just avoids the crash as it seems).

- Create a corona camera
- In the attributes manager, select the value 0 of the simple exposure and set it to -4.5
- Save it in the AM as a preset, for example "camera corona outdoors"
- If you try and load this preset, the value is reset to 0, not -4.5

Camera settings (in the section above) are not ignored, just tone mapping ones are.

I added a screenshot where I am saving the settings, just to be sure.

[C4D] Daily Builds / Curvature Shader
« on: 2022-02-04, 05:14:59 »
I really like what you did there, also the simultaneous access to concave and convex.
What I would like is a max distance texture, similar to what the AO shader has.

And, here I am not sure, would it be possible / useful to have it for concave/convex separately?

PS
I think it would be useful to give the node two extra outports: concave and convex that would deliver a greyscale intensity map that could be used as masks in a layer shader.

[C4D] Bug Reporting / Crash Boom Bang ... but hair?
« on: 2022-01-19, 01:07:33 »
Aside from being a bit ... not happy I am surprised.
When Corona crashed C4D this time (and no recovery scene was written), all I got was a bug report and a minidump.
But why on earth is this report mentioning a Corona Hair object when no hair nor hair material was somewhere near this scene?

And, is there any indicatrion what crashed this scene? I was adjusting materials while the IR was running ...

14
... whereas using a similar setup with a ray switch shader works.

The include/exclude in a light material does not work when the light material is applied to a sky object.
In the attached scene, neither the cylinder nor the plane should receive any light.

I guess, adding an exclude/include list to the Corona Sky object would already solve the greater part of this issue.
