I need help Cinema 4D / Re: Substance Painter to Corona C4D
« on: 2018-12-16, 00:41:57 »
There was a topic in the forum with similar discussion and explanations why some maps needs to be loaded linearly and others with gamma 2.2, but it could be hard to find it. For now just remember, that colour/diffuse texture in most cases must be loaded with embedded gamma. Glossiness, IOR, displacement, bump, anisotropy should always be loaded in linear.

iirc it was on the messy dubcat thread.

Coming from using Vray for years we're starting to bend towards Corona more and more.

What I love about Vray - and HATE in Corona is the way the Corona VFB handles renders.

If you store an image in the Corona VFB history you can only save out the base image.

Render elements aren't saved into the history so you can't save out any render elements.

In Vray - If you double click a render in the history, it opens up in the VFB (and loads elements in too).  You can then 'Save All'

In Corona I don't think you can do it.

Is there a fix/workaround for that?

I don't want to be mean but you cannot say you hate it if you haven't learn it yet. Yes you can, actually Corona VFB is very flexible and easy.

How to : Corona VFB Window > Save Icon > Put the mouse OVER and HOLD > Save as CXR = Corona own format for saving all the elements you added.

Now you can close Max or C4D, and open the CXR file using Corona Image Editor, you have all your render elements + post FX + light mix.

Let me know if you need more help.

Custom materials in the library should definitely be on the poll

Elaborate please? You can already make Material Librairies with Max. You mean you want to use the corona library window UI to manage your own libraries ?

Following this thread. I was an ex C4D Corona user and switched to Max. If there is a script that can avoid me some manual tasks I would love to even pay for it.

Here is a pretty good example of the ACES

I even requested OCIO in Corona just after I tested it in Arnold.

I wonder why Auto-Focus is not already a feature/available option. +1 for adding it officially.

I need help / Re: Using multiple HDRI's for lighting.

Thanks, I'll try to do that for the future. Unfortunately, good HDRI's are expensive for a student like me. I'd love to get some feedback from you on the lighting in the picture I have attached to this if you don't mind.

We met in the server in which we feedbacked on your render, I just reply here lately...

Glad you joined the discord. You will find free HDRI/Backplate or very affordable ones.

Last thursday our school had a visit from a guy from Sunday digital, who is making BMW commercials. I showed him my work, and got some feedback. In my scene i had simply rendered a car using HDRI lighting with a matching backplate. He said that, what they typically do is add additional fake lighting to the scene

Yep, exactly what I said, so far so good.

or rotating the HDRI and making multiple renders and then combine them in photoshop. (...) they get to the location early in the morning and start shooting photos there, and then take shots throughout the day so that they have different lighting

They must be taking different shots yes but never saw someone mixing morning sun light with after noon and sunset night light. It will look like crap to be honest. It's not even natural, not at all and I never saw that yet on any commercials.


If you want to improve your lighting and make it look professional : Get some Professional/High quality HDRI+Matched Backplates, add additional lights (area lights enough for you to start with, and it's what most pros uses).

If you are looking at automotive resources I made a place for that. You have a category on the left called RESOURCES :

Hmm, if those are (nice but still) "noisy test renders", then maybe they should stay in the WIP section?

Click on the Behance link, I explained why they are noisy.

Ooops, posted in WIP instead of Gallery. Miss clicked. Can it be moved ?

New project.. As you can see they are noisy tests renders. I had some issues and couldn't finish the project. I hope it's still enjoyable. Corona (beta) for Cinema 4D

Like in car photography they often take multiple shots of the car throughout the day to get different lighting

I'm specializing in photo realistic automotive rendering, and obviously have a huge interest for car photography (I have a photographer background) and I've never saw that in my life. They do it yes but with flash/spot light etc but never like you said. If they do, well, it must be one guy out of the millions of photographers out here.

Also never saw anyone mixing different HDRIs, we all switch between them, not use them like you do which is very uncommon and I don't see the point to be honest. I do like to see a convincing results with your technique because so far, I'm not sold. No offense of course, just my personnal opinion.

multiple hdri (...) at the same time in the render.

Using the slate editor, there is a way to mix them, in some kind of multiply/additive mode. Give it a try with a mix texture or something.

I don't understand why you want them "at the same time". You can switch between them in 2 mouse clicks, in 2s.

In max I'm using as many HDRI as I want using the slate editor :

- Import your HDRI using the CoronaBitmap
- Add a Corona_ColorCorrect map > Link it to the Scene Env map in Render Setup
- Plug each HDRIs in your correct Corona_ColorCorrect map to switch between as many HDRIs as you want + control gamma intensity etc if required.

That's for the look dev part. For the LightMix, I did not tried anything yet, not sure if it's possible since it will have to Render "behind the scenes" each HDRIs.

Can you upload the scene and the assets here ? This way the devs will be able to reproduce this issue and give you an proper answer.
