[C4D] Bug Reporting / Projector and NaN
« on: 2019-09-02, 00:27:12 »
A requester asked me to send this scene to the support and I am happy to oblige:
Win 10, C4D R20, Corona latest V5 daily. IR in the viewport.
The NaNny regularly and reliably appears when I dial up the offset in the projector shader.

[C4D] Bug Reporting / Projector shader not refreshing with IR
« on: 2019-09-01, 21:45:00 »
Open the attached scene.
Run IR (viewport, VFB, you choose).
Looks ok.
Open the mat, there the projector settings.
Increase the U offset.
IR goes yellow.
Restart IR.
Ok again.

[C4D] Bug Reporting / Disappearing objects in IR with "opacity material"
« on: 2019-08-26, 19:55:27 »
Load the scene and run IR in the viewport.
Drag the rightmost texture tag from the object "panzer oben" called "Metal - Gold.add" down in the object manager so it becomes the rightmost tag of the object "rock".
The object "panzer oben"becomes transparent in the viewport IR.
Restart the IR, thing go to normal.
Now reload the file, run the IR and deactive the SDS.
The drag&drop operation and the render results are as expected.

[C4D] Bug Reporting / Pop-Eyes
« on: 2019-08-13, 20:29:07 »
instructions to create a literal pop-eye:
open the scene and run IR in the viewport (or in the VFB, does not matter here) and drag the corona material onto the object "gnome". as soon as the IR resumes, the gnomes eyes pop out (actually, the skin deformer is no longer respected for the mesh and the mesh returns to its undeformed state).

[C4D] Bug Reporting / stacked Opacity layer causes wrong refractive rendering
« on: 2018-12-17, 22:11:11 »
Lest it gets lost:
Compare the rendering with and without a dust layer stacked upon the glass base material tag.
Without: no distortion, as expected.
Without: distortion, where from?
Bug?
Win 10, R20, latest daily.
PS
Physical (render, the native one in C4D) does not "do" it.
PPS
Yeah, added dust makes the renderer think the glass object is massive, not hollow, and renders it this way. Detection problem where object ends or something like this.

[C4D] Bug Reporting / Bug with colorized fragments / voronoi fracture
« on: 2018-12-16, 20:27:02 »
C4D R20, latest daily R3 Corona, Win 10
Render the attached scene. You will get (differently) tinted glass shards, despite the fact that "Colorize Fragments" in the Voronoi Fracture object should be "overwritten" as soon as you attach a texture tag to it.
Counter check: Switch "Colorize Fragments" off, no tinted shards.
It only shows this buggy behaviour with:
- An opacity manterial stacked on top
- With thin glass.
I could not reproduce this behaviour with physical (the C4D renderer), so I guess it is Corona related.

[C4D] Bug Reporting / IR and VfB/PV render differently
« on: 2018-11-30, 20:17:24 »
Render in PV and with IR. Different results, IR renders wrongly, PV and VFB correctly.
Ok, it's almost a hack with the correction deformer and the vertex map, but well ...
Needs R20+
Corona Beta 2, Window 10, C4D R20
Well, short correction:
To make the IR render wrongly, press play in the timeline and start IR.
If you stop the playback and restart IR, it renders correctly, too.

Stacking a "splotch" onto a "carpet" in this scene renders the "outside" of the splotch area wrong.

[C4D] General Discussion / Convert Scene: Hair
« on: 2018-11-21, 22:10:45 »
I think that it's already planned, so just a quick reminder:
Convert Scene creates a corona hair material from the C4D hair material but does not assign it. The conversion of the parameters is also bad. And if the current way the hair material works will be kept, a copy of the C4D hair material needs to be kept and be assigned to the object.
Light conversion (as well as Sky) does not work either.
I always work with corona materials and lights only, so a working coverter is a huge timesaver.

[C4D] Resolved Bugs / Hair Material: Level does nothing

According to https://coronarenderer.freshdesk.com/support/solutions/articles/12000039643-how-to-render-hair-and-fur- the level setting should render black hair at 0%.
This is not the case.

[C4D] Resolved Bugs / Hairs move with Hair object
« on: 2018-11-10, 18:26:52 »
- Render the attached scene, ok.
- Now move the Hair object. Anywhere you want to.
- Render again.
- The rendered hair "moved" with the hair object.
In C4D's native renderer, it does not matter where the hair object is. The guides and the rendered hair stays put where it is linked to.

[C4D] Resolved Bugs / "Rename" minimizes C4D
« on: 2018-10-28, 20:07:37 »
Now this one is weird. Tried it with Beta 2 RC 4 in C4D R20, latest, running under Windows 10 (latest, too).
- Create a new Corona material
- Create a Layer Shader in Diffuse
- In the Layer Shader, create a noise shader
- Doble click the word "noise" to rename it
- Do not rename it but click below the word in an empty area of the shader

[C4D] Feature Requests / Converter Vray Displacement
« on: 2018-07-21, 20:27:38 »
I have not followed this converter a lot, since I am not using VrayforC4D anymore, but today I tried it with an ancient scene.
Please handle the Vray Displacement material properly. It is of no use to convert it to a basic grey Corona material.
If you happen to stumble on such material, convert the following Vray Advanced material into a Corona one, take the values and shaders from the displacement material as good as possible and insert them into the Corona material's displacement channel. Then kill the Vray displacement material.
If the Vray displacement materials has a different projection than the following "standard" material, use a Projector shader to adapt the displacement accordingly.
Thx.
Michael

[C4D] Resolved Bugs / Triplanar in a C4D layer shader
« on: 2018-07-10, 16:26:58 »
Unpack the archive and load the scene. Render. Black!
It seems that triplanar and the C4D internal layer shader are not the best of friends. With two bitmaps (the same or two different ones does not matter) in this constellation, the result will always be black.
Replace the lower bitmap with a procedural noise. Works.
Replace the lower bitmap with a plain color (texture slot empty). Works.
The lower triplanar must not contain a bitmap.
This bug just occurs with Normal , other mix modes give, well, no black results at least.
Tested on Win 10, R19.053 and Corona B2 from May 30.
