I can't really understand what I am doing wrong. I am trying to light a room with all walls closed off, it has a floor and ceiling, and I have an area light at the ceiling to light the room. The area taken up by the light object is completely dark, and nothing I try can make the room ceiling light like the walls.
I added an omni light as well and that does not help at all.
How do I light the room without having this dark spot?
I move the light down but then the upper part of the ceiling is still dark but not very dark.
Is there no way to make a double-sided area light?
Also, when I try to change settings for the light in the Details tab and General tab any changes I make produce no changes to the light. Changing the falloff has no effect, area shape has no effect, etc.
What are we able to change for light settings?
CentiLeo lights, how do they work? I cannot make them more intense, Lights not able to brighten in IPR
Shadow catch pass (multi-pass) does not work under any settings, shadow catch never shows up, and I have tried many combinations of settings

Oh, I was using the centileo node material and just using the space here to handle my settings.
Is the old centileo material just as good in terms of updated tools? I just thought that the node one could have also had the emission right beside the other properties to make it easier to enable it. And as far as I can tell there is no way to customize the palette for C4D to have the old material icon where I keep my other centileo tools. EDIT: Interesting, I didn't notice before but using the old material instead of the node makes the colour applied to objects visible in the viewport, unlike the node material.

Rendering speed needs to be improved

Oh I see, changing the max iterations for the render also affects the IPR iterations. Thank you.

Actually, I found that lowering the max iterations decreases my render time by as much as the Decrease itself.
from 32 to 8 iterations I render from 20 minutes per frame to 5 minutes. How come the max iterations is so high by default? I cannot tell any difference between the 8 vs 32 iteration renders I tested. |

couldn't the check box to enabled/add emission be there always when making a material?

EDIT: Oh, I see it is in the node editor. But is there not a way to add it using the material editor instead of having to use nodes?

Animated image sequence or video file mapped to material? Is this possible or coming later?
User Posts:
I am trying to map a texture to a material, but the thing I want is an image sequence or video file to play animated on a plane surface or other object.
Is this going to be added at some point or is it possible now somehow? |

Turning all their shadow weights to 0 fixes everything. It was just confusing me that the beauty showed a certain shadow and the alpha showed extra shadows. Is there any reason that the two modes would show different shadows, when having and not having shadow catcher enabled? Is there a way to make them show the same shadows in both modes, particularly when viewing IPR? I had already checked those two boxes you mentioned that show the same lighting in IPR and render view Or is the simplest way to remember to change my shadow weights for every light source?

Does this make any sense? Even when changing my HDRi, lowering all the settings, even rotating it does not change the shadow shown here.
I can't make any sense of this. It only does this when I apply the shadow catcher. When I uncheck it the shadows all act normally.

I tried disabling all my lights, and this seems to show this now for the alpha.
But why would the lights on the tree not affect the shadow on the regular plane but burn out all shadow on the shadow catcher plane? Does it have something to do with that each of the cloned lights on the tree has shadow matte weight? But even stranger is when I disable the lights I am left with a new shadow that shouldn't exist. There should only be a shadow behind the tree, but no matter what I do my HDRi is somehow making a shadow in front of the tree that I cannot remove, but it only shows up in the alpha when I enable shadow catcher. Otherwise the shadow isn't there. And this shadow that shouldn't exist appears even if I turn the HDRi multiplier down to almost zero, including the shadow weight for it.

I cannot get any shadows to render in the alpha no matter what I try. Here is the scene with no shadow catcher applied, and here is the alpha of the same scene with shadow catcher applied. There is no shadow at all. I am not sure what to try. I have tried adjusting my HDRi settings and everything I can think of. My other scenes have worked and I have the same settings I have always used, but now with this one it doesn't render shadows for alpha.

Why does IPR lighting never look the same as final render? (too dark in render)
User Posts:
I thought transluceny would do it but it barely made my solid object see thru, it was only when I checked alpha in the material that it became transparent. Is this correct to make glass? I thought transparency and Alpha were different. |

User Posts:
I always have this issue where my IPR lighting looks great but my final render is very dark, and I have to relight everything after and render again.
I was trying to have my HDRi light multiplier turned down to almost 0, but since my IPR showed the light from my single omni light looked good enough I figured that would look ok rendered. turning my HDRi up gives the rendered scene more light, but why would it look so much different than in the IPR?

right now when I adjust the Alpha to reduce shadow strength in AE I lose a tiny bit of the beauty layer edge. |

The objects all have a halo of semi-transparency that I cannot get rid of. This is for the shadow layer I try with Extractor Effect and Levels Effect to reduce the alpha. It is only obvious when zooming in on the image. It is either a black ring around all the objects I render or the best I can make it is a faint ring using Levels Effects, but I cannot get rid of of it if I want to have my beauty pass separate. It looks like it is the alpha channel bleeding into the other parts of the render. My beauty pass works fine when I separate it from the alpha, but the alpha creates this border around my beauty. EDIT: If I remove the Extractor Effect this goes away.

Chrome material, how?

EDIT: That only happens with a metal texture I used that had Metalness but no Reflection to map.

How would I use the 'metallic' texture for a metal texture pack?
I have the colour texture and glossyness and reflection which I know where to map in the material, but what about metallic? Is that something I use on the reflection 2? I tried but could not use it with any effect on the object. |
IPR renders fine but Render to Picture Viewer generates black images?

Did you look at your task manager and see how much memory is actually being used?
Also, when you post here there is am option to upload files directly ("Upload files" link button). So you can put them right here in this thread. |
