[C4D] I need help! / make specific trees semi-transparent

« on: 2021-06-25, 13:30:54 »

Hi,
I'm working on a project where I would like to make some specific trees semi-transparent to show what's behind them.
I tried making the materials transparent, but with 3D trees, when too many leaves behind each other, the effect of transparency is lost (in the centre, on the edges the effect is as expected)

So, I was thinking I might need multipass (mask the objects?) and compositing, but (a bit shamed to admit ) I have never used multipass before so very newbie about that...

Can somebody explain me, what the best way is,  to do this, by detailed step or example file?

many thanks!

what exactly has changed in hotfix 2?
only S24 support or also certain bugfixes?
thanks, Koen

I often had those kind of white dots too, when using a HDR file as a visible background and typically only in direct lighting areas and on bumpy or displaced materials.

The white dots dissapear immeadiately whithout changing any settings when

i use a tonemapped bitmap (JPG/PNG) instead for the visible background+reflection+refraction+mask
  c4d sky object with tonemapped on/in it, add compositing tag and uncheck GI+shadows in the options
  OR
  when using the new corona sky object in shader/hdri mode , uncheck 'visible by GI' in the object properties)

and keep the HDRI only for GI lighting+shadows.
  c4d sky object with the HDR on it, add compositing tag and keep only GI+shadows checked in the options
  OR
  when using the new corona sky object, uncheck visible directly+refl+refr in the object properties
that worked for me

[C4D] Feature Requests / displacement enable/disable in render settings

« on: 2021-03-24, 14:31:15 »

it would sure be functional to have a displacement enable/disable option in the render settings
along caustics-motion blur-DOF enable/disable buttons

It could much improve performance and IR preparation time when not needed, p.e. when you're working on lighting or overall work on the scene

I really hope this can be integrated

+1 it's so time-consuming to rework all purchased assets that only exist for vray (such as designconnected)

[C4D] I need help! / zdepth for 360tour

« on: 2021-03-08, 11:39:01 »

Hi, I would like to render a zdepth images for a 360 tour on 'TheViewer' platform.
It will allow a more visual warping instead of just switching/fading from point to point.

Here is a tutorial/explanation for corona on 3Dsmax, but the parameters are a bit different for C4D and the option  'use camera environment range' is unavailable in C4d.
https://help.theviewer.co/article/64-6dof-in-360-vr-images-depth-map-quick-guide

I have not got much knowledge about multipass but when I simply activate zdept, the layer is plain black

is there a way to do this in C4D?
any help is much appreciated!

[C4D] Bug Reporting / R23 Asset browser

« on: 2021-03-04, 16:29:55 »

I think there is still some compatibility issue with Corona 6.1 and R23 Asset Manager.

I use the asset manager very intensly, to relink textures used from the Content browser presets to absloute paths,
because since version 6.1 there are serious performance issues with loading textures from presets (read: no absolute paths) and superslow rendering material previews.
Therefore I have to relink a few times every hour to keep C4D fast, the difference is really huge when using absolute paths everywhere.
But the actual problem I experience now is this:

When I use an IES light source, inside a corona light, from a preset (either a preset for IES database, or an IES included in imported lighting preset) it is impossible to replace or relink the IES file in the asset manager. It seems to work, and it's changing to the absolute path, but after a few seconds the path flips back to the preset IES. Equal when using the replace function.

When using a regular/native light this functionality works as expected...

Thanks for some info on this,

[C4D] Feature Requests / compositing tag sliders

« on: 2021-02-24, 22:19:55 »

Hi, replacing on/off switches in the compositing tag with sliders 0-100% would be appreciated.

p.e. sometimes a client asks me to reduce the cast shadows on the building for a specific tree... I know this is cheating but I would not know how to do this else but to render twice with and without shadows then blend in PS.
A slider for the shadows would then be very handy.
and the same goes for visibility.
(I believe this was also a feature in vrayforc4D?)

thanks for considering this...

[C4D] Bug Reporting / v6.1 shadow catcher rendering yellowin IR when change to reference

« on: 2021-02-10, 14:30:17 »

hi,

when I apply a shadow catcher to a surface and reference it in environment mode to a sky with HDRI material, everything is fine until I change something to the HDRI material.

This can be changing the intensity of the light material or inside a filter shader.
Only solution to continue is restarting IR

so for the included test file:
1) start IR
2) change the intensity of the sky, and surface becomes yellow

when using the hdri directly in the sky, I can change the sky intensity or change color in a filter shader without it turning yellow, but if I
1) duplicate the sky
2) put the second sky in a null
3) make the null invisible (with second sky inside)
the floor surface with the SC turns yellow again

I don't know how this responds in v7, but it is equal on R18-R19 and R23 with v6.1

[C4D] Bug Reporting / v6.1 invisible reference objects for render instance still render in IR

« on: 2021-02-10, 13:33:52 »

hi,

I have a habitude to organize all my decorative objects and furnitures in an invisible null called 'symbols'. Then I make render instances and place them in the scene.

However when the 'render instance' option is enabled for the instance, the original reference object is also rendered in IR (not final render), even when parent is set to invisible for rendering.

I am including a quick test scene to see if you can reproduce the error:
1) start IR as is on startup file, it renders only the instance as expected since the render instance is disabled.
2) enable the render instance in the object manager
3) restart IR and both the render instance and reference object are also rendering now, while this is not expected behaviour since the parent is set to invisible.

We have had this problem on R18 and R19 since v5,v6 and 6.1, and tested with same results in R23 v7 too
my workaround  is to lower my symbols null to height -5000, but it needs to restart the IR to see it dissapear. With parsing times often around 6 minutes, it's quite a pain to see p.e. a reference tree in the middle of the livingroom...

cheers, koen

[C4D] General Discussion / Re: Fireflies

« on: 2021-01-18, 13:03:53 »

About fireflies,... I'm not sure if this is the solution you are looking for, but I've had my share of frustrations how to get rid of them and at the end I found that I had better results if the sky reflections were not produced by a HDR/EXR file but rather with a regular bitmap.
So now I have the habitude to seperate the two like so:
 
I have a sky with a JPG/PNG/TIF , with compositing tag to enable for background/reflections/refractions/mask
and a sky for lighting with HDR/EXR file with compositing tag to enable for GI and shadows

Again, I'm not saying this is the better way to go, but it works for me...

Cheers,

[C4D] General Discussion / Re: VR and 360s

« on: 2020-12-18, 14:53:46 »

I have been rendering some 360 tours now and it's quite easy with corona. After some experimenting to get the optimal resolution for oculus go, I was set to go

I just didn't think it was easy to get/copy the 360 images onto the oculus, especially for the clients, so I ended up with a subscription at www.THEVIEWER.co you should look into it, it's a great tool.

A new feature there, that i haven't used yet, is the zdepth map integration for more fluid warping from point to point
if someone has a tip or workflow to quickly render the zdepth map for a 360 project in coronac4d, I'm very interested to know how...

[C4D] I need help! / foreground object

« on: 2020-11-19, 09:49:10 »

Hi,

I read this post reggarding what I needed to do, rendering foreground somehow, but someone wrote thet it didn't work anymore with corona 6: https://forum.corona-renderer.com/index.php?topic=15842.0

Is there a way render a foreground object or something equal in v6(.1) ?
Some advice/workflow would be appreciated!

thanks, Koen
