[C4D] I need help! / Re: imperfections on edges

« on: 2020-01-09, 23:20:17 »

thx @beanzvision
i tried to tweak it. but as i tried on another object (for example 200x100x10cm) the shader is messed up (stretched).
i ended up by manually deforming the edges. it took too loooong... :o(

would be nice if there's an easier way to get such results in future.
i like the round edges feature and always use it. not only bump should work with it, but displacement, too ;o)

[C4D] I need help! / interactive viewport & shifted cameras

« on: 2020-01-09, 23:05:22 »

hi everyone
i came across a strange behavior, when using interactive viewport (c4d r21, mac high sierra) and shifted camera.
no matter which settings (use render/selected view) are active, it isn't showing the exact shifted camera view. the view is moved horizontally. "film offset x" is kinda messed up
> see attached images

does anybody having the same issue?
thx for your inputs

[C4D] Bug Reporting / Re: Ambient Occlusion

« on: 2020-01-09, 22:40:57 »

thank you @beanzvision for uploading a sample, how grime can be added at the bottom, without affecting the vertical edges. unfortunately i wasn't able to put it on top (top to bottom, without vertical edges). "outside" mode always puts the grime at the bottom not on top. any idea? ;o)

i also attached some samples of the private project i'm working on. the materials (stone, concrete) are made as a mix of a base shader (with ao) and a stacked dirt shader (controlled by noise & gradient). i'm very happy with the result so far!
 
thanks for all your support. i really appreciate! corona renderer and its team is amazing!

thanks for your answers so far.

@houska:
this methode is very time-consuming. i'm looking for a "global" solution by edge shader.

@rojharris:
okay, thanks for the hint.

@houska:
basically i'm doing architectural renderings (interior & exterior) > adding imperfections to edges would be a "killer"-feature in corona! :oD
would be on my wishlist for future releases :o) but i don't know if this will ever be possible...!?

so...how would you personally add imperfections to edges at the moment?

[C4D] I need help! / imperfections on edges

« on: 2020-01-02, 15:32:01 »

hi to everone, and happy new year!

i don't know if there is already a topic for this...
i want to add some imperfections to edges of an object for a close-up render. for example a concrete wall, where the cement is missing in some places (broken off)
> see attached image.

1. i tried to solve it with a texture in the bump slot of round edges
    > didn't work very well / it wasn't satisfying enough, as far iim searching for a realistic look.

2. i tried to solve it with a displacement map and beveled edges.
    > the problem here is...the height of the displacement is the same on both, surface and beveled edge.
    > would be nice if there is a way to handle displacement separately. one slot for surface, one for edges ;o)

back to my request...
is there any way to accomplish this?

i thank you for your help and inputs.

wow, thank you very much for your help and the example! that's exactly what i was looking for. :o)

if i may ask one last question...
is it possible to have the ao only on the bottom or top of an object?
already tried it with a gradient as a layer mask, but it wasn't satisfying enough.

i attached the c4d-file, wherein i tried to accomplish it.

thanks for answering.
in the meantime i was able to get a simple gradient (no shader, only value "max. distance").
but i still didn't figure it out how to use ambient occlusion by shader (noise etc.), as it should produce a shaped gradient (by noise, bitmap etc.)

[C4D] Bug Reporting / Ambient Occlusion

« on: 2019-12-16, 18:57:11 »

ambient occlusion is not working properly or at all, i guess. it only creates a small amount on the edge. no matter how high i set the "max. distance".
i did everything as it is supposed to do (helpdesk and tutorials)

does anybody have an idea or similar problems?
