[Max] Bug Reporting / Re: Corona Sun getting detached from target

« Last post by maru on Today at 11:49:06 »

Hi, please always do state which exact version of Corona and 3ds Max you are using. Are you using Corona 11 Hotfix 2 - https://corona-renderer.com/download ?
If not, please download it and check with that version.
Also, which version of Corona were your scenes originally saved with?

If you have any scene where this can be consistently reproduced, please submit a new support ticket and attach it (archived with all assets): https://support.chaos.com/hc/en-us/requests/new

[Max] Feature Requests / Re: Masks for Decals

« Last post by maru on Today at 11:46:33 »

You mean render elements, right? You would like to render your image and have decals as masks so that you could for example select a specific decal in a 2D editor?

[C4D] I need help! / need help with Cinema 4d Versions

« Last post by mapa on Today at 11:46:27 »

I had to reinstall my Cinema 4d versions because Windows was destroyed.
Now i realized that the Cinema 4d updater for content library  and newer updates is not function anymore.
Maxon told me since 1 year.

They gave me a link with R21.207 with content library
I run R20.059 without content library
I run R19.008 with content library
I run R18.020 with content library

Can someone tell me the number of the last version of each build (R21, R20, R19, R18)
So I can contact Maxon again.

Thanks

[Max] Feature Requests / Re: Motion-blur support when using map sequences / animated textures

But that workaround is only for long-time exposure and wouldn't work for 'normal' motion blur like the usual 0,5 frames and fast moving objects unless you stretch all your animation to something that you can render out. Or you would need to offset frames in the camera by tiny bits.

Motion blur for textures is such a nice to way to trick your way around certain problems, please try... (same for Distance Map)

This was requested in the past and I am afraid there are some technical reasons why this cannot be done. I will double check that and will report it as a feature request if it's not there yet.
There is however a workaround that you can use to get "true" motion blur whatever you are rendering:
- Render a sequence
- Save each frame as a CXR file
- Use a low pass limit (e.g. 2 passes - if we render 100 frames with 2 passes the quality will be like rendering a single frame for 200 passes)
- Once the rendering is completed, open the Corona Image Editor, click the "Merge" button and pick your rendered frames
This should result in correctly blending all frames just as if it was single frame rendered for x number of passes. The result should look exactly like a photo with long exposure. The advantage here is that you can still control exposure and other post/tone mapping params.
The disadvantage is that you cannot control the shutter curve.

+100 here. I requested this before, too, it's a must have (just like motion blur support for Distance Map).

[Max] Feature Requests / Motion-blur support when using map sequences / animated textures

« Last post by marchik on Today at 10:13:32 »

I'm experimenting with long exposure photography and suddenly realized that the corona renderer does not allow me to get an image with motion blur if the animation is done using textures.

The most obvious example is the surface of water shot at a long exposure. The only thing I can do to recreate it is to make a simulation using PhoenixFD (which is unacceptable for large spaces such as a river or sea) or use a Displace modifier with very strong surface subdivision - which is also not acceptable for large spaces.

I can't use the PhoenixFDOceanTex map in the displacement slot because Corona doesn't support motionblur for changing topology. And the strangest thing I found out is that I can’t get motion blur when I put it in the bump slot, because animated textures in the material do not affect the motion blur in any way.

The second example is a TV screen shot with a long exposure, if I animate the image on the screen using a image sequence, it wont work and I will not get this "cumulative light effect" that will be in photography.
The same goes for simply animating a static texture map if I animate its tiling, offset, and so on, corona won't get this into account when creating motion blur.

And of course it would be nice to finally get motionblur with a changing topology during displacement, at least with a PhoenixFdOceanTex map, I hope it will be possible to come up with a solution with your colleagues from the head office so that it works in some “special way”, just like motion blur works in regular simulation using PhoenixFD

[C4D] Daily Builds / Re: C4D scenes dont open with new Daily Build from Corona 12 March 11.

« Last post by frv on Yesterday at 23:25:09 »

I am actually very happy we have the daily builds. It's also really easy to install the latest stable release so I am never stuck.

Wonder though what changed recently that causes slightly older bigger files to stall. Pity I can't use the new scatter trimmer in the latest daily build. Would have like to use that in a projects I have been working on for a while now.
